## FAQ

**How do I check that a fire protection company in San Marcos 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 protection company need in Texas?**

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 Marcos to work there?**

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