Phoenix plumbing licensure at a glance
389 active ROC plumbing licenses are registered in Phoenix. Every Arizona license carries a scope, and it is a legal boundary rather than a size tier: 284 of Phoenix's licenses are dual scope (residential and commercial work) and 105 residential-only, while commercial-only licenses never appear on these pages at all - they do not permit residential work in Arizona. Tenure is what these pages rank on, and Arizona's issue dates are real and filled on every record: the median Phoenix license has been held 5 years, the longest-standing since 1971, and 30 (7.7%) have been held 25 or more years. The posting list carries no insurance, no bond and no phone for any licensee - Arizona requires a license bond by statute but does not publish it, so we never show one, never claim one, and never rank on one. ROC's contractor search cannot link straight to a record, so every listing above shows its number for you to paste into ROC's contractor search. How we verify.
Plumbers in Phoenix: common questions
How many licensed plumbers are there in Phoenix?

What does the scope on an Arizona plumbing license mean?
Arizona's scope is a legal boundary, not a size tier: a commercial-only license does not permit residential work, so commercial-only contractors never appear on these pages at all. 284 of Phoenix's 389 licenses are dual scope (residential and commercial) and 105 are residential-only.
How do I check a plumber's license in Arizona?
Every listing above shows its ROC license number. ROC's contractor search cannot link straight to a record, so open it and type the number in: it shows the class, scope, status and expiration. The median Phoenix license has been held 5 years, and the longest-standing dates to 1971.
