Find Licensing, Training, and Registration Records

The TCEQ oversees 10 programs for occupational licensing and registration (see list of licenses and registrations below).

By clicking on the link below, you may find licensing and training records for individuals and registrations for companies. Or you can search for specialized groups based on various search categories.

Search Licensing and Training, or Registration Information

Search results for individuals will include:

  • their address and work phone number,
  • their license number and effective and expiration dates,
  • CEUs earned and needed for renewal, and
  • a list of training records on file with the TCEQ.

Search results for companies will include:

  • their address and phone number and
  • their registration number and effective and expiration dates.

If an individual or company has never been licensed or registered by the TCEQ, the search will return no results. Please make sure to enter all search terms such as spelling surnames and company names correctly.

You can also find groups of licensed individuals and registered companies based on specific criteria including program area, type of license, city, county, TCEQ region, CEUs earned, and issuance or expiration date by using group search criteria.

In addition, this link will provide a list of registered OSSF maintenance providers in your area.
This file lists the individuals (providers) and companies currently issued registrations by the TCEQ. Under this registration program, individuals and companies who provide service or maintenance for on-site sewage facilities using aerobic treatment are required to register with us. (Note - If the word "NONE" appears under the Maintenance Company Category, this means that no company has been associated to the maintenance provider at this time.)
