How to check an Arizona plumber's license

Plumbing contractors in Arizona are licensed by the Arizona Registrar of Contractors (ROC). License numbers are six digits, and the ROC's contractor search shows whether a license is active and which classification it covers. The ROC issues separate residential, commercial and dual licenses, so make sure the classification fits a home job.

The ROC requires a license bond, but it does not require general liability insurance (workers' compensation aside). Ask the company for proof of insurance before work starts.

Before you hire

  • Look up the six-digit ROC number and confirm the status is active.
  • Check that the license class covers residential plumbing.
  • Ask for proof of insurance and a written estimate.
