Frequently asked questions

How do I check that a fire extinguisher company in San Antonio is licensed?

Search the company name or registration number in the Texas State Fire Marshal's Office public lookup (https://appscenter.tdi.texas.gov/reports/p/sfmo). Every company listed here shows its registration numbers and expiration dates, re-checked against state records on each data refresh.

What license does a fire extinguisher company need in Texas?

Companies doing this work must hold a Texas SFMO Fire Extinguisher Certificate of Registration (ECR). Texas requires a State Fire Marshal's Office certificate of registration for each type of work: fire alarm (ACR), fire extinguisher (ECR) and fire sprinkler (SCR). Individual technicians must also hold SFMO licenses.

Does a company need to be located in San Antonio to work there?

No. Texas registrations are statewide, so companies based elsewhere in Bexar County or across Texas can work in San Antonio. Confirm the service area with the company.
