Where to look for your business license number

Your business license number is printed on the physical license document itself, usually in the upper right or left corner. If you have the actual license in hand, that is the fastest place to find it. The number is typically a sequence of digits, sometimes with letters mixed in, and may be labeled as "License Number," "License ID," or "Permit Number" depending on your state and local jurisdiction.

If you cannot locate the physical document, your state or local government website holds a searchable database. Most cities and counties maintain a public registry where you can search by business name, owner name, or address to pull up your license details. The process varies by location, but the information is usually free to access online.

Key Takeaways

  • Your license number appears on the physical license document itself, typically in a corner or at the top of the page.
  • City and county government websites usually host searchable databases where you can look up your license by business name or owner name.
  • Your accountant, bookkeeper, or business formation service may have a copy of your license number on file.
  • If you registered through a service like LegalZoom or a local business formation company, they often keep records you can request.

Checking your city or county government website

Start with your city or county clerk's office website. Most maintain a "Business License Search" or "Permits and Licenses" section where you can enter your business name and see all active licenses tied to that name. Some jurisdictions also let you search by owner name or street address.

The exact steps depend on where you are located. In many cases, you will land on a page with a search box, type your business name, and receive results showing your license number, issue date, and expiration date. If your city does not have an online search tool, you can call the business licensing department directly and provide your business name and address; they can read the number to you over the phone.

Contacting your state's business registration office

If your business is registered at the state level — which is common for corporations, LLCs, and partnerships — your state's Secretary of State office or Department of Revenue maintains a public registry. Most states allow you to search their business database online by company name.

Go to your state's Secretary of State website and look for "Business Search," "Entity Search," or "Corporation Search." Enter your business name and you will see your state registration number. This is different from a local business license number, but many businesses have both. If you are unsure which one you need, check the document or form that asked for it — it will usually specify "state" or "local."

Checking your records and past correspondence

Look through emails, letters, or documents from when you first obtained your license. The government office that issued your license typically sends a confirmation letter or email that includes the license number. Check your email inbox and spam folder for messages from your city or county clerk, business licensing department, or health department (if you operate a food business or similar regulated operation).

If you filed your business formation documents through a registered agent or business formation service, they may have sent you a copy of your license or a summary document that includes the number. Check any folders or files labeled "Business Formation," "Licenses," or the name of the service you used.

Asking your accountant or bookkeeper

If you work with an accountant, bookkeeper, or tax professional, they likely have your license number on file. They use it for tax filings and business records, so a quick call or email to their office can get you the answer when ready. This is often the fastest route if you have an existing relationship with someone managing your business finances.

Similarly, if you used a business formation service like LegalZoom, Rocket Lawyer, or a local business attorney, they keep records of all documents filed on your behalf. You can contact them and request a copy of your license or the license number itself.

What to do if you cannot find your number

If your license has expired or you cannot locate any record of it, contact your local business licensing office directly. Bring or provide your business name, owner name, and business address. They can tell you whether a current license exists and provide the number, or they can walk you through the process of renewing or obtaining a new one.

Some jurisdictions require you to renew your license annually or every few years. If your license expired, you may need to renew it before you can use the number for official purposes. The licensing office can confirm the status and next steps.

Frequently Asked Questions

Is my business license number the same as my EIN?

No. Your EIN (Employer Identification Number) is a federal tax ID issued by the IRS, while your business license number is issued by your city or county. You may have both, but they are separate numbers used for different purposes. Your license number is for local business registration; your EIN is for tax and payroll.

Can I search for someone else's business license number?

Yes. Business license records are public information in most jurisdictions. You can search any business by name or address using your city or county's online database. This is useful if you need to verify that a contractor or vendor holds a current license.

What if my business operates in multiple cities or states?

You may need multiple license numbers — one for each city or county where you operate, plus a state registration number. Search each jurisdiction's database separately. Your accountant or business formation service can tell you which licenses you hold and where.

Do I need my license number to renew my license?

Usually not. Most renewal notices include your license number, and you can renew using your business name and address. However, having the number on hand makes the process faster. If you receive a renewal notice, keep it in a safe place for future reference.

Where do I find my license number if I just started my business?

Check the confirmation letter or email from your city or county clerk. If you obtained your license in person, it should be printed on the document itself. If you have not received anything yet, contact the licensing office to confirm your process was processed and ask them to provide your number.
