Delaware SOS Business Search 2026: LLC & Entity Lookup

Delaware entity lookup • file number • status • tax • certificates

Find and Verify a Delaware Entity Record

Search a Delaware LLC, corporation, partnership or statutory trust by entity name or file number, then learn exactly what the free record confirms—and what it does not.

This guide also explains paid status checks, registered agents, franchise-tax deadlines, annual reports, name reservations, certificates and the steps to restore an entity that is no longer in good standing.

Independent guide. This website is not the Delaware Division of Corporations and does not operate the state entity database.

The key fact most lookup guides miss

The free Delaware entity search returns both active and inactive records. Finding a company in the results does not prove that it is currently in good standing.

Complete the Delaware SOS Business Search Step by Step

The official search accepts an entity name or file number. It is not case sensitive, and quotation marks can be used for an exact-name search.

Choose name or file number

Use the file number when available. Otherwise, begin with the entity’s legal name or distinctive wording.

Search a broad name first

For “Atlantic Harbor Technology Holdings LLC,” try “Atlantic Harbor Technology” before entering the entire legal name.

Use quotation marks only for an exact search

An exact search can help when many similar names appear, but it can also miss spacing, punctuation or legal-suffix variations.

Compare the result names and file numbers

The results list includes active and inactive entities. Do not interpret appearance in the list as current good standing.

Open the entity information page

Review the file number, formation date, entity type, residency and registered-agent information.

Decide whether free information is enough

For basic identification, it may be sufficient. For current status, filing history, franchise-tax information or an official certificate, use the appropriate paid service.

Automated-search warning: the Delaware Division of Corporations prohibits data mining and excessive automated searches that can affect its systems or customer experience.

After choosing the correct search input and understanding the status limitation, use the official real-time entity search.

Free Delaware Record vs Paid Status Information

The free search is useful for confirming identity and registered-agent details. It is not a free certificate-of-good-standing service.

Included in the free entity search

  • Entity name
  • Delaware file number
  • Incorporation or formation date
  • Entity kind and type
  • Domestic or foreign residency
  • Registered-agent name
  • Registered-agent address
  • Registered-agent phone information when displayed
Common mistake: a business can appear in the free results even when it has been cancelled, dissolved, forfeited, merged, converted or voided for unpaid tax.

Use the paid online status service only when an immediate informational status check is sufficient. Order an official certificate when the receiving party requires formal evidence.

Read a Delaware Entity Record in the Right Order

Use this five-part order to confirm that the record matches the business named on a contract, payment request, certificate or transaction document.

1. Entity name
2. File number
3. Kind and type
4. Residency
5. Registered agent
Record field What it means Common mistake Useful next check
Entity name The legal name held in the Division of Corporations database. Assuming a brand, website or payment name is automatically the legal entity. Compare the contract and any Delaware or local trade-name records.
File number The identification number assigned to the Delaware entity record. Confusing it with a federal EIN or Delaware business-licence number. Use it for status, annual-tax and document requests.
Formation date The date shown for incorporation, formation or Delaware registration. Assuming the entity has continuously remained active since that date. Obtain status or filing history when continuity matters.
Kind The broader legal category, such as corporation, LLC, partnership or statutory trust. Calling every Delaware entity a corporation. Apply the tax and annual-report rule for the correct kind.
Type A more specific classification within the entity kind. Ignoring differences between stock, non-stock, exempt or alternative entities. Review forms, tax instructions and certificate language for that type.
Residency Whether the entity is domestic to Delaware or foreign to Delaware. Assuming foreign means outside the United States. For a foreign entity, verify the home-jurisdiction record if needed.
Registered agent The person or company authorised to receive service of process and official notices. Treating the registered agent as the owner, manager or operating address. Use transaction or company records for ownership and management evidence.
Agent address The Delaware physical address maintained for registered-agent service. Assuming it is the company’s headquarters or customer location. Verify the company’s actual business address separately.
Delaware-specific reality: many entities are formed in Delaware but do not physically operate there. A registered-agent address in Wilmington, Dover, Newark or Lewes does not prove that the company’s employees, offices or commercial activity are located at that address.

What Delaware Entity Statuses Mean

Use the exact status wording. Different inactive statuses point to different legal events, tax problems or registered-agent failures.

Status Plain-English meaning What to check next
Good Standing The entity’s existence has not been terminated voluntarily or administratively. Confirm whether the receiving party needs an official certificate rather than an online status result.
Voluntarily Cancelled The entity filed a cancellation after dissolution and winding up. Review cancellation and any later revival or renewal filing.
Dissolved A corporation voluntarily filed a certificate ending its legal existence. Check whether a revocation of dissolution or revival occurred later.
Expired An LLP or LLLP did not file its required annual report on time. Review reinstatement and outstanding annual-report requirements.
Forfeited—Failure to Appoint Agent The registered agent resigned and a replacement was not appointed within the required period. Appoint a qualifying Delaware registered agent and complete the required renewal or revival process.
Cancelled—Failure to Pay Tax An LLC, limited partnership or partnership failed to pay annual tax for three years after it became due. Calculate back taxes, penalties and required renewal filings.
Consolidated A merger-and-consolidation filing terminated the original entity and created a new entity. Identify and search the new resulting entity.
Merged The entity ceased as a separate record through a merger into another entity. Obtain filing history to identify the surviving entity.
Converted The business changed from one entity type or jurisdictional form to another. Follow the conversion filing to the resulting entity record.
Void or Tax-Related Inactive Status The entity failed to meet required franchise-tax or annual obligations. Obtain a current status and tax assessment, then determine revival requirements.
Good Standing is not a licence or endorsement. It does not prove that the business is insured, financially stable, authorised for a regulated profession, free from litigation or operating legally in every state.

No Delaware Entity Found? Use This Search-Recovery Order

A missing result often comes from narrow wording, a changed name, a trade name or confusion between corporate registration and a Delaware business licence.

Check spelling. Compare the name with a certificate, contract, tax notice or formation document.
Remove punctuation. Delete commas, periods, apostrophes and hyphens.
Remove the legal suffix. Search without LLC, Inc., Corp., LP, LLP or Ltd.
Use the distinctive wording. Drop generic terms such as holdings, ventures, group or services.
Avoid quotation marks initially. Exact searches can miss spacing and suffix variations.
Search a previous name. The entity may have amended its legal name.
Search the file number. This bypasses name variations entirely.
Check another jurisdiction. A company operating in Delaware may have been formed elsewhere.
Check a trade name. A Delaware business can advertise under a name different from its entity name.
Check business-licence data. Corporate registration and Delaware operating-licence records answer different questions.
Consider an unincorporated business. A sole proprietor may not have a Division of Corporations entity record.
Contact the Division. Provide the name variations, file number and document or transaction involved.

Check and Reserve a Delaware Entity Name

Name availability is a separate tool from the general entity-information search. An available name can be reserved, but reservation is optional and does not form the entity.

Run these searches before reserving

  • Full proposed legal name
  • Distinctive wording without LLC or Inc.
  • Singular and plural versions
  • Common spelling variations
  • Names with similar abbreviations
  • Names that sound similar
  • Relevant federal trademark records
Name-rights warning: Delaware name availability or reservation does not establish federal trademark rights and does not guarantee that another party cannot challenge the name.

Use the official availability and reservation service only after checking similar names and deciding that temporarily holding the name is useful.

Delaware Annual Tax and Report Deadlines

The most important distinction is between corporations and alternative entities. Delaware LLCs generally pay an annual tax but do not file the corporation annual report.

Domestic corporation

Annual report and franchise tax

Due March 1

The report and prior-year franchise tax are filed online. Late filing creates a $200 penalty plus 1.5% monthly interest on unpaid tax and penalty.

LLC, LP or GP

Annual alternative-entity tax

$300 due June 1

These entities generally do not file a Delaware annual report. Late payment creates a $200 penalty plus 1.5% monthly interest.

Foreign corporation

Annual report

Due June 30

The filing fee is $125. A $125 penalty is added when the annual report is not filed by the deadline.

Domestic corporation franchise-tax methods

A stock corporation can generally calculate franchise tax under the Authorized Shares Method or the Assumed Par Value Capital Method. The state advises using the method that produces the lower tax when eligible.

Authorized Shares Method Minimum $175

Up to 5,000 authorised shares produces the minimum tax under this method.

5,001–10,000 shares $250

Each additional 10,000 shares or portion adds $85 under the published method.

Assumed Par Value Method Minimum $400

This calculation uses issued shares and gross assets and can produce a lower amount for some corporations.

Large balances: corporations owing $5,000 or more may have quarterly estimated-tax payments: 40% due June 1, 20% September 1, 20% December 1 and the remaining balance March 1.
Closed business does not automatically mean no tax is due. If an entity remains active in Delaware’s records during a tax year, tax can continue to be assessed until the appropriate dissolution, cancellation, withdrawal or other termination filing is completed.

After identifying the entity type and correct deadline, use the applicable official tax or annual-report portal.

What a Delaware Registered Agent Does

Every Delaware entity must maintain a registered agent and a physical registered office in Delaware. The registered-agent address may have no connection to the company’s day-to-day operations.

Registered-agent responsibilities

  • Receive service of process
  • Receive official state communications
  • Maintain a physical Delaware street address
  • Provide billing and tax communications to represented entities
  • Remain properly appointed on the entity record
Failure-to-appoint risk: if an agent resigns and the entity does not appoint a replacement within the required period, the record can move into a forfeited status.

Use the state’s registered-agent guidance when forming an entity, replacing an agent or investigating a forfeited record.

Choose the Right Delaware Status or Certificate Product

Ask the receiving party exactly what it requires. A free search result, paid online status response and official Certificate of Good Standing are not interchangeable.

Free entity information

Use for basic identification, formation date, entity type and registered-agent information.

$10 online status

Use for an informational status check when an official certificate is not required.

$20 detailed information

Can include current franchise-tax assessment, filing history and additional entity information.

Certificate of Good Standing

Use when a bank, lender, government agency or transaction party requires official evidence.

Certified copy

Use when the requester needs an officially certified copy of a specific filed document.

Plain copy

Use when you need the document content but do not require formal certification.

Ask the requester: “Do you need an online status result, a Certificate of Good Standing, a certified copy of a specific filing, or an ordinary filing copy?”

How the certificate-request process works

  1. Confirm the entity name and Delaware file number.
  2. Choose Document Filing and Certificate Request in eCorp Business Services.
  3. Select the certificate or filing-copy type.
  4. Enter complete submitter and return-delivery information.
  5. Add expedited service only when the deadline justifies the added fee.
  6. Save the request confirmation and tracking information.

Certificate validation

Delaware provides online validation for qualifying certificates issued by the Division of Corporations. Validation requires the entity file number and authentication number and is available for one year from the certificate’s issue date.

Delivery detail: official forms guidance says regular requests are returned by first-class or regular USPS mail unless an eligible FedEx or UPS account is supplied for express return.

Delaware Expedited-Service Fees Explained

Expedited fees are added to the normal filing, certificate or service charge. Do not select expedited processing before confirming the submission cutoff and whether the request qualifies.

Service level Published additional fee General submission cutoff
One-hour service $1,000 Generally received by 9:00 p.m. Eastern Time.
Two-hour service $500 Generally received by 7:00 p.m. Eastern Time.
Same-day service Usually $100–$200 depending on request Generally received before 2:00 p.m. Eastern Time.
Next-day service Usually $50–$100 depending on request Generally received by 7:00 p.m. Eastern Time.
Timing is not mailing time: processing completion and return delivery are separate. Provide an eligible express-carrier account when the physical return deadline matters.

Restore a Delaware Entity to Good Standing

The recovery process depends on why the entity became inactive. A cancelled LLC with unpaid tax follows a different path from a corporation that lost its registered agent.

Prepare before filing

  • Confirm the exact entity and file number
  • Purchase or obtain the current status information
  • Identify every unpaid tax year
  • Calculate penalties and interest
  • Identify missing annual reports
  • Confirm the current registered agent
  • Choose the correct revival, renewal or reinstatement form
General renewal rule: Delaware states that restoring good standing can require the appropriate filing plus all back taxes and filing fees. Obtain the current tax and filing information before estimating the total.

Use the renewal forms only after confirming the exact status and whether the entity still exists in a form that can be revived or renewed.

Use the Correct Delaware Business Tool

An entity registered with the Division of Corporations may not physically operate in Delaware. Corporate registration and a Delaware business licence answer different questions.

Entity name, file number or agent Use the Division of Corporations entity search. Entity search
Current entity status Use the paid online status service or request an official certificate. Status options
Business operating licence Use Delaware One Stop or Division of Revenue resources. An entity record does not prove an active operating licence. Delaware One Stop
Professional licence Use the Division of Professional Regulation for regulated occupations. Professional licence search
UCC financing record Use the Division’s separate UCC service for secured-transaction filings. Delaware online services
Federal EIN An EIN is issued by the IRS and is not normally displayed in the public Delaware entity result. Use authorised IRS or company records.
Local-operation check: a company can be legally formed in Delaware while operating entirely in another state. Verify the entity’s authority, licence and address in the state where the actual transaction or work occurs.

Contact the Delaware Division With a Useful Question

Have the file number, entity name and exact service request ready. The Division no longer provides entity filing history through live chat, so use the proper history or document-order service when that is what you need.

Prepare before contacting support

  • Exact entity name
  • Delaware file number
  • Entity kind and type
  • Current status wording, when purchased
  • Tax year or annual-report year
  • Document or certificate requested
  • Submission or order number
  • Required completion and delivery date
Phone script: “I am checking [entity name], file number [number]. I need to determine [status, tax balance, filing history or certificate type]. Which official service or request form should I use?”

Delaware SOS Business Search FAQs

Is the Delaware entity search free?

Yes. The basic entity-information search is free. It provides the entity name, file number, formation date, entity classification, residency and registered-agent information. Current entity status and official documents require another service.

Does appearing in the Delaware search mean a company is active?

No. The search returns both active and inactive entities. Appearance in the free results is not confirmation of current status or good standing.

Can I search a Delaware LLC by file number?

Yes. A Delaware file number is the most precise way to locate one entity record and avoids confusion between companies with similar names.

What information appears in the free Delaware business record?

The free record generally includes the entity name, file number, incorporation or formation date, kind, type, residency and registered-agent name, address and phone information when displayed.

How can I check whether a Delaware company is in good standing?

Use the Division’s paid online status service for an informational check or order an official Certificate of Good Standing when formal proof is required. The free entity search does not confirm status.

When is Delaware LLC annual tax due?

Delaware LLCs generally pay a $300 annual tax due on or before June 1. They do not file the corporation annual report. Late payment creates a $200 penalty plus 1.5% interest per month.

When is a Delaware corporation annual report due?

An active domestic corporation’s prior-year annual report and franchise tax are due by March 1. A foreign corporation’s annual report is generally due by June 30.

Is a Delaware registered agent the company owner?

Not necessarily. The agent receives service of process and official communications at a Delaware physical address. Professional agents can represent thousands of unrelated entities.

How much does a Delaware name reservation cost?

The current reservation fee is $75, and an approved reservation is effective for 120 days. Reservation is optional and does not create the entity.

Is a Delaware entity search the same as a business-licence search?

No. The Division of Corporations search identifies legal entities registered in Delaware. Use Delaware One Stop, Division of Revenue or the relevant professional board to verify operating and occupational licences.
