How to check a plumber's ROC license

Arizona licenses contractors through the Registrar of Contractors, and the register is public. Ask for the license number, then look it up on the Registrar's website. It will show you the license status, the classification, who holds it and the complaint history. Ours is ROC #359690.

How to look one up

  1. 01

    Ask for the ROC number. Arizona contractors are required to put it in their advertising, so it should not be hard to find

  2. 02

    Go to the Arizona Registrar of Contractors website and use its public license search

  3. 03

    Search by the license number, or by the business name if you only have that

  4. 04

    Check the status is active, and check the classification covers plumbing work

  5. 05

    Look at the name on the license and whether there is any complaint history

What to actually read

  • Status: an active license is the whole point of the check
  • Classification: a license is for specific kinds of work, so a plumbing job wants a plumbing classification
  • The qualifying party and the business name, which should match who you are talking to
  • How long the license has been held, and whether it has lapsed and been renewed
  • Complaints, and what came of them

Why this check is worth two minutes

A license is not just paperwork. It is what makes a contractor answerable to a state body, it is what a permit gets pulled under, and it is what backs the work if something goes wrong later.

The Registrar also runs a recovery fund for residential work done by licensed contractors, which is another reason the license status matters before work starts rather than after.

Answers

More on this

What is Ironwood Valley Plumbing's license number?

ROC #359690. It is on every page of this site, and you can look it up on the Arizona Registrar of Contractors website without asking us for anything.

Does every plumbing job need a licensed contractor?

Arizona sets a threshold below which some small work can be done unlicensed, and it is narrower than people assume. For anything involving gas, sewer, water heaters or work that needs a permit, licensed is the answer.

Is bonded the same as licensed?

No. Licensing is the state registration. A bond is a separate financial instrument. Both are worth asking about, and neither one is insurance.
