How do I check a concrete contractor's license in Arizona?
The short answer
Use the Contractor Search on the Arizona Registrar of Contractors website, roc.az.gov, to review the contractor's license record. Make sure the license class allows the work in your contract. Concrete work falls under classes such as R-9 for residential, C-9 for commercial, and CR-9 for both. You can also call the Registrar to confirm.

Look up the license
The Arizona Registrar of Contractors tells homeowners to review the contractor's license record using the Contractor Search on roc.az.gov.
The Registrar says the only sure way to know a contractor is licensed is to call the Registrar to confirm it, or to check the Contractor Search.
If you need help using the search, the Registrar invites you to call. The Phoenix office number is (602) 542-1525.
Check the license class
The Registrar issues separate licenses for commercial and residential work, and dual licenses that cover both.
For concrete, the Registrar lists R-9 Concrete (residential), C-9 Concrete (commercial) and CR-9 Concrete. CR-9 allows the scopes of work permitted by both C-9 and R-9.
The Registrar says to make certain the contractor's license class allows for the work listed in the contract.
Why it matters
The Registrar says an entity must be licensed to be a contractor in Arizona, and that you have no recourse through the Registrar if you hire an unlicensed entity.
A licensed contractor must hold a bond, among other requirements. The Registrar says advertising that claims a business is licensed, bonded and insured is not proof that it is.
