South Dakota SOS Business Search 2026: LLC Lookup

South Dakota entity lookup • LLCs • agents • filings • good standing

Verify the Right South Dakota Business Record

Find a South Dakota LLC, corporation, nonprofit or partnership by legal name or Business ID, then use the separate registered-agent or DBA-owner search when the standard entity search cannot answer the question.

Read the record correctly, trace filing images, verify standing, prepare annual reports, correct outdated information and choose the right certificate or reinstatement action without depending on a thin directory page.

Independent guide: this website is not the South Dakota Secretary of State and does not operate the Business Services database.

Start with the free Business Information Search

Search by legal name or Business ID. Use Starts With for a reliable beginning, Contains for uncertain wording, and leave Active Entities Only unchecked whenever an old, delinquent, dissolved or revoked record could matter.

What Are You Trying to Find?

Choose the result you need. This helper does not search the live database; it identifies the correct official tool and the checks to complete there.

Find an LLC or corporation

  1. Use the Business Information Search.
  2. Enter the distinctive part of the legal name.
  3. Compare Business ID, entity type and status.
  4. Open the detail page and review filings and standing.

Choose the Correct South Dakota Search Method

South Dakota separates entity, registered-agent, DBA-owner and exact name-availability searches. Choosing the wrong tool is the main reason visitors believe a record is missing.

Business name

Search registered LLCs, corporations, nonprofits, cooperatives, LLPs and other entities by legal name.

Use Starts With or Contains. The standard search does not provide a general owner field.

Business ID

Use the Secretary of State identifier to open one exact entity and avoid similarly named results.

This is not an EIN, sales-tax licence or professional-licence number.

Registered agent

Use the separate free agent tool to search by first, middle and last name, agent number or agent business name.

One commercial agent can represent hundreds of unrelated companies.

DBA or owner

Use the fictitious-name database to search by DBA name, DBA ID, city, filing date or registered owner.

This is the useful official route for the “search by owner” intent when a trade name is involved.
Name availability is a different task. The availability page tests one exact proposed name and displays a preliminary result. Use the broader entity search first to compare spelling and sound-alike variations.

What Should You Type in the Official Search?

Start with the smallest distinctive wording that can identify the business. Add words only after the results are too broad.

What you knowSearch to runWhy it worksWhat to avoid
Prairie Wind Solar LLCStarts With: Prairie WindFinds the legal name even if the ending or extra wording differs.Do not begin with the entire punctuated name.
A middle phrase such as “Equipment Holdings”Contains: Equipment HoldingsWorks when unknown words may appear before the phrase.Do not use Starts With when the first word is unknown.
A Secretary of State Business IDBusiness ID lookupOpens the exact record and bypasses similar names.Do not enter an EIN in this field.
An old contract or dissolved companyName search with Active Entities Only uncheckedKeeps delinquent, dissolved, revoked and historical results visible.Do not filter to active entities before locating the record.
Only the person or agent serviceRegistered Agent SearchReturns entities linked to the agent name or valid RA number.Do not assume the agent owns every result.
A storefront or advertised brandDBA search by name or ownerConnects the trade name to its registered owner.Do not assume adding “LLC” to a DBA created an LLC.
Fast mobile method: copy the distinctive words into your phone notes before opening the portal. Also save the Business ID once found; it is the quickest key for reports, certificates, copies and support.

Complete the Official Entity Lookup Step by Step

Use this sequence to avoid choosing a similarly named company or hiding a dissolved record with the Active Entities Only filter.

Start with the legal or advertised name

Copy the wording from a contract, invoice, website footer or filing notice. When you know only a brand name, be prepared to run a separate DBA search.

Choose Starts With or Contains

Starts With works well when the first words are reliable. Contains is better when the legal name may include extra words before or after the wording you know.

Search fewer distinctive words first

For “Black Hills Property Management Solutions, LLC,” begin with “Black Hills Property.” Remove punctuation and entity endings such as LLC, Inc. or Corporation when the full wording returns nothing.

Decide whether to use Active Entities Only

Leave this box unchecked when researching a former company, previous contract, dissolved entity, old filing or reinstatement problem. Check it only when historical results are unnecessary.

Compare the result list

Match the full legal name, Secretary of State Business ID, entity type and status. Similar names can belong to completely unrelated businesses.

Open the detail page

Review the formation jurisdiction, principal office, registered agent, annual-report due date and the available filing or image history.

Check the newest filing before relying on the result

An annual report, agent change, amendment, dissolution or reinstatement can explain why information elsewhere is inconsistent or outdated.

The official search is free and allows viewing and printing individual entity information after you complete the search choices above.

Read a South Dakota Business Record in the Right Order

Use the record to answer three questions in order: Is this the correct entity? Is its registry standing current? Which filing explains the latest information?

Record itemWhat it tells youWhat it does not proveUseful next check
Business nameThe current legal entity name recorded by the Secretary of State.That every brand, storefront or invoice uses this name.Search the DBA database when the public-facing name differs.
Name typeHelps distinguish a legal, former, reserved, registered or other recorded name.That the name is available for a new filing.Use the exact availability search only for a proposed new name.
Business IDThe South Dakota SOS identifier assigned to that entity record.It is not a federal EIN or South Dakota tax account.Use it for annual reports, certificates, certified copies and support.
Entity typeThe registered structure, such as LLC, business corporation, nonprofit, cooperative or LLP.That the company holds every occupational or local licence.Apply the annual-report and reinstatement rule for that exact type.
Filing dateWhen the entity or listed name entered the SOS record.Continuous operation since that date.Look for later dissolution, revocation, withdrawal or reinstatement filings.
Formed inWhether it is domestic to South Dakota or formed in another jurisdiction.A foreign entity remains active in its home state.Check the home-state registry for high-value transactions.
SOS statusThe entity’s overall registry condition, such as Good Standing, Delinquent, Dissolved or Revoked.Tax compliance, insurance, financial condition or reputation.Read annual-report and registered-agent standing separately.
Principal officeThe principal business address reported to the state.That customers can visit or that it is the agent’s office.Compare it with the newest annual report and transaction documents.
Registered agentThe individual or organisation designated for official notices and service of process.Ownership or authority to negotiate a transaction.Use the agent search and review the most recent agent-change filing.
Annual-report due dateThe report deadline shown under the anniversary-month rule.The report has already been accepted.Check the newest report filing and standing indicators.
Filing historyThe public trail of creation, reports, amendments, agent changes, dissolution and reinstatement.That bylaws, operating agreements or ownership ledgers were filed.Open the newest relevant image or order a certified copy when formal evidence is required.
Internal documents are not available from the SOS: corporate bylaws and LLC operating agreements are company records, not Secretary of State filings.

Use the Detail Page as an Action Dashboard

After opening the correct entity, use the record to decide the next action rather than returning to Google for another generic guide.

Open filing images

Read the creation filing, newest annual report, amendment, agent change, dissolution or reinstatement that affects your question.

Record the Business ID

Save it once. It is required for precise searches, annual reports, good-standing certificates and certified-copy orders.

Check the report due date

Use the displayed anniversary month to determine the next report date and whether an early filing window is open.

Compare all standing fields

Read overall SOS status, annual-report standing and registered-agent standing before describing the entity as current.

Choose ordinary or certified evidence

A free screen print is useful for research; banks, licensing agencies and courts may require a certificate or certified copy.

Verify completion later

After filing, search again and confirm that the expected document and updated standing actually appear.

Do not rely on a single screenshot forever. Save the search date, Business ID and the filing used. A later annual report, agent change or status action can alter the public record.

Understand Status, Annual-Report Standing and Agent Standing

South Dakota’s certificate screen separates the overall SOS status from annual-report and registered-agent standing. Read all three before saying a company is in good standing.

Good Standing

The entity’s SOS status and required standing checks are current enough for the state to issue an online Certificate of Good Standing.

Still verify licensing, tax, insurance and the identity of the person contacting you separately.

Delinquent

An annual report has not been filed within the required period. A delinquent entity can generally use the annual-report tool to file missing reports and pay the applicable late charge.

Check every missing report year; filing only the newest year may not restore good standing.

Dissolved (Administrative)

A domestic entity has been administratively dissolved after unresolved compliance problems such as reports, agent maintenance or unpaid filing charges.

Use the reinstatement process rather than the ordinary annual-report route alone.

Revoked

This commonly affects an entity whose authority or qualification has been revoked. The next action differs by entity and domestic or foreign status.

Foreign entities cannot use the domestic reinstatement route and must apply again for a Certificate of Authority.

Historical dissolution, termination or withdrawal

Voluntary closure, termination or withdrawal can remain searchable even when the business is no longer active.

Open the filing that created the status and look for a later revocation, reinstatement or new authority filing.
Good standing is not a universal approval. It does not prove the company has paid every tax, holds a trade licence, is insured, is solvent, has no lawsuits or is endorsed by the state.

No Business Found? Use This Search-Recovery Order

A zero-result search often means the wording or tool is wrong—not that the business is fictitious.

Verify spelling. Compare the name with a contract, state letter, invoice or website footer.
Remove punctuation. Try the wording without commas, periods, apostrophes or hyphens.
Remove LLC or Inc. Search the distinctive words without the entity ending.
Switch from Starts With to Contains. Extra wording may appear before the words you know.
Use fewer words. Generic terms such as services, holdings or solutions can hide the best match.
Uncheck Active Entities Only. A dissolved, revoked or terminated entity will otherwise be hidden.
Search the Business ID. Use it when found on a report, filing, certificate or state notice.
Search the registered agent. This is useful when only the agent name or agent company is known.
Search the DBA database. A storefront or website name may be an assumed name rather than a legal entity.
Search a DBA by owner. The owner field exists in the fictitious-name search, not the standard entity search.
Consider an unregistered structure. A sole proprietor or general partnership may be represented mainly by a DBA record.
Confirm the state and official domain. Use only the South Dakota portals shown in this guide for a South Dakota registration.
Contact Business Services. Provide the attempted names, Business ID if known and the exact result you expected.

Choose the Right Evidence: Free Record, Certificate or Certified Copy

A searchable detail page answers research questions. A Certificate of Good Standing or certified filing is used when a bank, lender, licensing body, court or another state requires formal evidence.

Online certificate checklist

  • Find and copy the Secretary of State Business ID.
  • Confirm that the correct legal entity appears before payment.
  • Check overall SOS, annual-report and registered-agent standing.
  • Pay the $20 online fee with an accepted debit or credit card.
  • Download the colour PDF immediately.
  • Save the verification number with the PDF.
  • Use the official verification field when another person needs to authenticate it.
Save the PDF before leaving the download page. The SOS says the online certificate is not emailed or mailed and is no longer available from that page after you leave.
Not eligible through this certificate tool: general partnerships, reserved names, registered names and DBA/business-name registrations.

Use the official certificate service only after determining that certified standing—not merely a free public record—is what the requester needs.

Find Filing Images, Archived Records and Certified Copies

The detail page contains public filing history. The method depends on the filing date and whether you need an ordinary image or certified evidence.

Most records from 1994 onward

Check the online detail page

Most entity images from 1994 to the present can be found through the filing history and image links.

Before November 2016

Use the older image-link path

For initial filings before November 12, 2016, look for the blue ID number beside the Initial Filing history item.

Before 1994

Request archived records

Archived documents must be requested from the Business Filing Office and are charged at $2 per page.

Certified-copy limitations

The online certified-copy service requires a Business ID and lets you select from available documents. Documents dated before November 14, 2016 are not available for online certified-copy ordering, so older requests may need direct office assistance.

South Dakota Annual Reports: Due Date, Fees and Late Status

The report is generally due every year on the first day of the anniversary month. Limited partnerships and business trusts are the stated exceptions.

Entity or ruleCurrent requirementPractical example
Business corporation, LLC, cooperative or LLP$55 online; $70 on paper when the $15 paper-processing charge applies.Use the live portal for the lowest listed filing method.
Nonprofit corporation$10 annual-report fee; nonprofit corporations are exempt from the additional delinquent-report late fee.Do not use the standard $55 fee for a nonprofit report.
Limited partnership or business trustThe SOS FAQ lists these as exceptions to the annual-report requirement.Do not force an LLC or corporation deadline onto these records.
Due dateFirst day of the anniversary month of the original filing.Filed June 11, 2026 → first report due June 1, 2027.
Early filingThe report can be filed about two months before the due date.A June 1 report can be filed beginning April 2.
DelinquencyDelinquent status and late fees begin two months after the due date.June 1 due date → delinquency begins August 1.
Current late feeThe current FAQ and fee schedule state $55 per delinquent report.Identify every missing year before calculating the total.

Who can use the online report tool?

  • Active entities filing an original annual report
  • Delinquent entities filing outstanding reports and late fees
  • Users with the Secretary of State Business ID
  • Filers with current addresses and entity-specific officer, director, governor, shareholder, manager or partner information
  • Users paying by Visa, MasterCard, Discover or American Express

Use another process when

  • The entity is dissolved or revoked
  • You are correcting a previously filed report
  • The registered agent must be changed separately
  • You do not know every delinquent report year
  • The entity type is exempt from annual reporting
Official fee conflict: the live annual-report instruction and older PDF forms still show a $50 late fee, and an older LLC form prints a $65 paper fee. The current SOS FAQ and fee schedule state a $55 late fee, $55 online report and $70 paper report for the standard entity categories. Use the live checkout total.

After submission

  1. Download the receipt and acknowledgment immediately.
  2. Search the entity again after processing.
  3. Confirm that the report year appears in filing history.
  4. Recheck annual-report standing and the next due date.
  5. Keep the receipt when the status update is not immediate.

Correct the Right Record Instead of Filing the Wrong Form

A new annual report does not automatically correct an older report, registered agent, legal name or formation document. Match the error to the proper filing.

What the amended annual-report PDF shows

The July 2025 domestic business-corporation form lists a $30 filing fee and allows correction of the filing year, Business ID and name, principal executive-office address, governors or shareholders, and optional beneficial-interest information. Other entity types have their own forms, so do not reuse the corporation form for an LLC or nonprofit.

Do not overwrite history by guessing. Identify the year and document that contains the error, then use the form for that entity type. Keep a copy of the correction and confirm that it appears in filing history.

Restore a Dissolved or Revoked South Dakota Entity

Domestic reinstatement combines delinquent reports, fees, tax clearance when required, registered-agent corrections and a mailed application. Foreign entities use a different route.

Confirm the entity type and exact status

Identify whether the record is a domestic LLC, business corporation, nonprofit, LLP or foreign entity. Do not use a domestic reinstatement form for a foreign record.

File every delinquent annual report

The online preparation process requires all missing reports and applicable late fees before producing the reinstatement application.

Request tax clearance

The current reinstatement guide expressly requires an approved Department of Revenue Tax Clearance Certificate for LLCs and business corporations. Revenue sends the approved certificate directly to the SOS.

Correct the registered agent before reinstatement

When the agent name or address is wrong, submit the separate Statement of Change before the reinstatement application.

Complete the printed application

The domestic LLC PDF asks for the exact legal name and Business ID, effective dissolution date, a statement that the grounds were eliminated, confirmation that the name complies, required reports and fees, and the authorised signer.

Mail the application and fee

The preparation tool produces a printable application. Mail it with the correct entity-specific reinstatement fee after completing every prerequisite.

Verify restoration in the public record

Search the entity again and confirm the SOS, annual-report and registered-agent standing. A tax-clearance email or payment receipt alone is not final proof.

Domestic LLC$150Plus delinquent reports, penalties and other required filings
Business corporation$300Plus delinquent reports and fees
Nonprofit corporation$30Plus delinquent reports and required corrections
Domestic LLP$125Available for up to two years after revocation
Tax-clearance wording differs across official pages. The current reinstatement guide names LLCs and business corporations, while the broader SOS FAQ says all for-profit entities must request tax clearance. A for-profit entity type not clearly named should confirm the requirement with Business Services before mailing.
Foreign entities cannot reinstate. A revoked foreign LLC, business corporation or nonprofit must apply again for a Certificate of Authority.

Check Name Availability Without Confusing It With Entity Search

The availability page is an exact preliminary check. It displays its own data timestamp, but final acceptance still occurs when the formation filing is reviewed.

Use the availability tool when

  • You have one exact proposed legal name
  • You have already searched similar and sound-alike names
  • You are preparing a new entity filing
  • You understand that the result is not a reservation or approval

Use entity search instead when

  • You want Starts With or Contains matching
  • You need dissolved or historical entities
  • You are researching an existing business
  • You need to compare punctuation, spelling or sound-alike variations

Search sound-alike names, not only spelling

The SOS gives the example that “Philips Avenue Diner” and “John Philips Avenue Diner” can be distinguishable after adding a meaningful word, while “Dear LLC” and “Deer LLC” sound alike and may not be distinguishable even though they are spelled differently.

Optional 120-day name reservation

The official reservation form holds an eligible name for 120 days for a current $25 fee. The same applicant may not reserve the same name again until more than 60 days after the reservation expires. The name must include the designator required for the entity type. A reservation does not create the company.

Regulated-word warning: a proposed entity name containing “TRUST” requires approval from the South Dakota Division of Banking. The SOS FAQ says these formations cannot be filed online and must be submitted on paper.

Search a South Dakota DBA by Name or Owner

A DBA or fictitious business name identifies an assumed name and its registered owner. It does not create an LLC, corporation, nonprofit or partnership.

DBA questionSouth Dakota rulePractical action
Who generally files?A person or entity regularly conducting business under a fictitious name, unless the name plainly shows every interested person’s true surname or the name is already in a required SOS filing.Check the statutory exception before registering.
How can I search?Search by DBA name, DBA ID, city, date range, status or registered owner.Use the owner field only in the separate DBA system.
Registration fee$10 per name, whether filed online or through a county Register of Deeds.Save the registration confirmation after payment.
DurationFive years from the filing date.Renew before expiration; an expired record must be filed as new.
Amendment$10 per name when an ownership interest or owner/business address changes.Update the record instead of leaving a former owner or address.
CancellationNo filing fee.The registered owner can cancel online or through a county office.
Searchable historyActive records filed after July 1, 2004, plus expired or cancelled records for up to one year after the event.Contact the appropriate office when an older record is not online.
Renewal-window conflict: the DBA service page permits renewal within 90 days before expiration, while the SOS FAQ says the renewal period begins 30 days before expiration. Use the live renewal screen to determine current eligibility.
A DBA does not protect exclusive name rights. The SOS describes its role as ministerial and does not regulate name misuse or decide infringement disputes.

After confirming that the public name is a DBA rather than the legal entity name, use the official owner/name search or filing service.

Find or Change a South Dakota Registered Agent

The registered agent receives official notices and service of process. Use the separate free agent search when you know the person, agent organisation or valid RA number.

Agent type or taskOfficial requirementWhat to prepare
Noncommercial agentA South Dakota-resident individual or eligible business entity registered in South Dakota.Full legal name plus physical and mailing addresses in South Dakota.
Commercial registered agentAn agent or organisation registered with the SOS as a commercial agent.Obtain the CRA number directly from the commercial agent.
Office-holder agentAvailable for some organisations, but the SOS states this option does not apply to LLCs.Use only when the organisation and office qualify.
Search an agentSearch by first, middle and last name, agent number or agent business name.Expect a professional agent to appear with unrelated entities.
Change agent or officeThe current fee schedule lists $10.Business ID, old agent, new agent or CRA number, South Dakota addresses and authorised signature.

Form details that prevent rejection

  • Use the exact Business ID and legal name.
  • Identify the agent currently on file.
  • Complete only the noncommercial or commercial-agent option that applies.
  • Provide a South Dakota physical address, not only a P.O. box.
  • Enter the commercial agent’s CRA number when applicable.
  • Have an authorised officer or person sign and date the filing.
Stale PDF fee: the February 2018 LLC Statement of Change still prints a $25 fee. The current statewide fee schedule and other agent materials list $10. Use the live filing screen for payment.

What the South Dakota SOS Search Does Not Show

The database is a public filing system. It is not a complete ownership, tax, licence, court or financial-risk report.

Use the SOS record for

  • Legal entity identity
  • Secretary of State Business ID
  • Entity type and formation jurisdiction
  • SOS, annual-report and agent standing
  • Principal office and registered agent
  • Public filing history and document images
  • Annual-report due date
  • Good-standing certificate eligibility

Verify elsewhere for

  • Federal EIN or S-corporation election
  • Federal tax-exempt classification
  • South Dakota sales-tax account
  • Professional or occupational licence
  • Complete LLC membership or share ownership
  • Insurance and bonding
  • UCC financing statements
  • Lawsuits, judgments or consumer complaints
Beneficial-owner limitation: South Dakota business entities may report beneficial owners in some filings, but the SOS says they are not required to do so. The absence of a name is not proof that the person has no ownership interest.

Avoid Filing Delays and Verify the Result

The official PDFs identify the same preventable errors repeatedly: missing signatures, wrong fees, incomplete registered-agent addresses and unavailable names.

Before submitting

  • Use the exact legal name and Business ID.
  • Choose the form for the correct entity type and domestic/foreign status.
  • Complete every required South Dakota agent-address field.
  • Use the current fee schedule rather than the fee printed on an old PDF.
  • Sign and date the filing with the correct authorised role.
  • Keep a copy of every attachment and payment confirmation.

Common delay or rejection causes

  • Unsigned filing
  • Incorrect or missing fee
  • Registered-agent address not fully completed
  • Proposed name unavailable or not distinguishable
  • Using an annual report to make a change requiring another form
  • Submitting a foreign entity through a domestic reinstatement path

Verify the Business Before You Sign or Pay

Use the SOS record to match the legal party behind a proposal, invoice, lease, purchase or service agreement.

Match these details

  • Legal entity name on the agreement
  • Secretary of State Business ID
  • Entity type and formation state
  • Overall SOS status
  • Annual-report standing
  • Registered-agent standing
  • Principal-office address
  • Newest annual report or amendment
  • DBA connection when a trade name is used

Investigate these red flags

  • Payee name differs from the legal entity and DBA
  • Business ID belongs to a different company
  • Entity is delinquent or administratively dissolved
  • Contact person is not shown in any relevant filing
  • Bank details changed through an unexpected message
  • Required professional licence cannot be verified
  • Address differs without a recent filing explanation
Record limitation: a good-standing business can still be involved in a scam, and a legitimate small business may operate as a sole proprietor under a DBA. Verify the transaction, payee and required licence—not only the entity name.

Contact South Dakota Business Services With a Useful Question

Prepare the Business ID, exact status and filing problem before contacting the office. Staff can explain records and filing procedures but cannot choose an entity type or give legal or tax advice.

  • Entity type and formation jurisdiction
  • Exact SOS, annual-report and agent-standing labels
  • Report year, filing date or certificate request
  • Payment, receipt or delivery reference
  • Name variations and filters already tried
  • Screenshot of the error with card data removed
Phone or email script: “I am checking the record for [legal name], Business ID [ID]. The detail page shows [exact status and standing]. I already tried [search or filing action]. I need to know which official form or process applies to [specific problem].”

South Dakota SOS Business Search FAQs

Is the South Dakota SOS business search free?

Yes. The Business Information Search lets users search, view and print individual entity information for free. Certificates, certified copies, database downloads and filings have separate fees.

Can I search a South Dakota business by owner?

Not through the standard entity search. The SOS says ordinary LLC and corporation ownership is not filed as a complete searchable record. The separate DBA database can be searched by registered owner, and entity filings may show organizers, incorporators, directors, managers or governors.

Can I search by registered agent?

Yes. Use the separate free Registered Agent Search and enter the individual’s first, middle and last name, a valid agent number or the agent business name. A registered agent is not automatically an owner.

What is a South Dakota Secretary of State Business ID?

It is the identifier assigned to the state entity record. Use it for exact lookup, annual reports, good-standing certificates, certified-copy requests and support. It is not an EIN or sales-tax number.

What does Good Standing mean in South Dakota?

For certificate purposes, the entity’s overall SOS status, annual-report standing and registered-agent standing must permit issuance. Good standing does not prove licensing, tax clearance, insurance, solvency or customer reputation.

How much is a South Dakota Certificate of Good Standing?

The current online fee is $20. Download and save the colour PDF and verification number immediately because the SOS says the certificate is not emailed or mailed and cannot be downloaded from that page after leaving.

When is a South Dakota annual report due?

It is generally due each year on the first day of the anniversary month of the original filing. An entity filed June 11, 2026 generally has its first report due June 1, 2027, and the filing window opens about two months early.

What happens when an annual report is late?

The entity becomes delinquent two months after the due date. The current SOS FAQ and fee schedule list a $55 late fee per delinquent report, while nonprofit corporations are exempt from that additional late charge. Continued delinquency can lead to administrative dissolution.

Can I amend a South Dakota annual report online?

The online tool is for original annual reports. To correct a previously filed report, use the appropriate entity-specific Amended Annual Report paper form. The domestic business-corporation form currently lists a $30 filing fee, but other entity types use their own forms.

Can a revoked foreign entity be reinstated in South Dakota?

No. The official reinstatement guide says revoked foreign LLCs, business corporations and nonprofits must apply again for a Certificate of Authority rather than use domestic reinstatement.

Freshness note: the official search interfaces, fees and forms were rechecked on August 4, 2026. Where an older PDF conflicts with the live fee schedule or current FAQ, this guide identifies the conflict and directs the visitor to the live transaction screen for the final amount and eligibility.
