Check an electrician’s, A/C contractor’s or plumber’s license

Before you let someone wire, cool or plumb your home, see what the state has on file: whether the license is listed or active, what kind it is, and when it expires. Texas and Colorado, from each state’s own published files.

Choose the state, then search by full name, business name or license number (like EC17000).

The states and what their files show

Texas. TDLR’s files: electrical contractors, electrical sign contractors, master, journeyman, sign, industrial and maintenance electricians, residential wiremen, A/C contractors and A/C technicians. They have no status column: a license in the file is listed with its expiration date, and one that leaves the file is shown as no longer in it. TSBPE’s files: responsible master, master, journeyman and tradesman plumbers and plumbing inspectors, with their status. Texas files record a county, so the directory is by county. Apprentices are left out.

Colorado. DORA’s licenses for the State Electrical Board and the State Plumbing Board: electrical and plumbing contractors, master and journeyman electricians and plumbers, residential wiremen and residential plumbers, with their status and any public disciplinary action. Apprentices are left out.

What this does not tell you Complaints, permits, insurance, or how good the work is. A license on file means the state has licensed someone for the work shown, and that is all it means. Ask for references and read reviews.

Questions people ask

How do I check if an electrician or A/C contractor is licensed in Texas?

Choose Texas and search the name, the business name or the license number. The result comes from the Texas Department of Licensing and Regulation’s published license files, as copied on the date shown. Confirm anything important on TDLR’s own lookup, linked on every result.

Why does a Texas license say "listed" and not "active"?

TDLR’s files have no status column. A license in the file is listed there with its expiration date; when it leaves the file, its page here says it is no longer in the file. TSBPE’s plumbing files and Colorado’s file do give a status, and we show it as written.

How do I check a plumber’s license in Colorado?

Choose Colorado and search the name or license number. The result comes from the Colorado Department of Regulatory Agencies’ open data, read live, with any public disciplinary action the file records.

Does a license mean the contractor is good?

No. It means the state has licensed them for the work shown. It says nothing about complaints, insurance, permits or quality. A license, not a review.

Can I have my page taken down?

Yes. Every license page has a Remove this page link. It takes the page off this site and out of our sitemap; it does not change anything on the state’s own lookup.
