# How to check an extinguisher company’s license

Check the official agency record and the scope of work before you accept a quote.

Updated 2026-11-10. Also on the [web page](https://extinguishers.fyi/guides/check-fire-extinguisher-company-license).

Ask for the exact legal business name, license or registration number, issuing agency and the name of the person who will perform the work. Then check the agency record yourself. A business name match alone is not enough to establish the scope of a credential.

## A worked route for Texas

The Texas Department of Insurance Fire Industry Licensing page has an Extinguishers section and a Company and individual search link [TDI, source below]. Start there. Use the agency link rather than a contractor's screenshot or an advertisement.

TDI describes the search as covering companies and personnel licensed by the State Fire Marshal's Office [TDI]. Check the business and the relevant person. Compare the number and legal name with the quote. Read the displayed credential type, status and expiry details. If you cannot establish that the proposed work is covered, ask the agency.

## Other states and Canadian provinces

Use the fire marshal or other responsible licensing authority for the location of the work. Ask that authority which credentials apply. Do not assume the Texas process applies elsewhere. Keep the agency's answer with your procurement notes.

## Membership and certification

Record a trade membership, a technical certification and a license in separate fields. Ask the issuer to confirm any credential you rely on. A directory listing, membership badge or paid placement does not answer whether someone may do the proposed work.

## Save evidence

Keep the source URL, date checked, legal name, credential number, status and scope. If the record is unclear, leave the field unknown and ask for clarification. Before work starts, compare the contractor on site with the business named in the agreement.

## Questions

### Is a directory badge a license?

No. Check the issuing agency and the scope of the credential directly.
