Notes
Arizona does not issue a statewide individual journeyman plumber license. The Arizona Registrar of Contractors licenses plumbing contractors in classifications including CR-37, C-37, and R-37, while local jurisdictions such as the City of Phoenix issue journeyman plumber credentials for work performed under local building code requirements.
