Texas Plumbing License Lookup
Enter a Responsible Master Plumber number to see its status, expiration date and whether insurance is on file - checked against 9,328 licences from the TSBPE roster.
How to read the result
Current means the licence is in good standing on the roster as of August 2026. Expired means it is not - do not proceed on the basis of an expired licence.
We show the expiration date separately because the roster is a daily snapshot. A licence that lapsed since the export still reads Current in our copy, so we flag that case rather than showing a green tick.
Insurance on file reflects the insurance expiry date the TSBPE holds. Texas requires proof of insurance to hold an RMP licence.
For anything consequential, confirm against the state's own live lookup. Ours is a daily copy; theirs is authoritative.
Common questions
What does a Texas plumbing license number look like?
M-##### - the letter M, a hyphen, then five digits. Texas law requires the Responsible Master Plumber licence number to appear on all advertising and on any vehicle used for plumbing work.
Where does this data come from?
The Texas State Board of Plumbing Examiners's published RMP roster, downloaded August 2026. We republish it unedited. No company can pay to change what it says.
The license says Current but the expiration date has passed. Which is right?
Treat it with caution. The roster is a daily snapshot, so a licence that lapsed after the export still reads Current in our copy. We flag that case separately rather than showing a clean result. Check the state's live lookup for the authoritative answer.
I searched a number and got nothing.
Either the number was mistyped, or no such licence has been issued. Re-enter it carefully. If it still returns nothing, that is meaningful information about whoever gave it to you.
