Verify a plumber licence in Colorado

Check a plumber's licence in Colorado by number or by business name and get one normalized JSON record back, sourced from the Department of Regulatory Agencies (DORA), Division of Professions and Occupations.

Try a free lookup — no signup, right here on this page. For programmatic access, take a free API key — 250 requests a month, no card. Also on RapidAPI and, if you would rather not write code at all, the Apify Store.

Which CO classifications count as plumbers

• PC — Plumbing Contractor — the business licence
• MP — Master Plumber
• JP — Journeyworker Plumber
• RP — Residential Plumber

A record's classifications array carries these codes, so you can tell a licence that covers the work from one that merely exists.

Run it

curl "https://contractor-license-verification2.p.rapidapi.com/v1/licenses/CO/PC.1209" \
  -H "X-RapidAPI-Key: YOUR_KEY" \
  -H "X-RapidAPI-Host: contractor-license-verification2.p.rapidapi.com"

PC.1209 is a real CO licence (Beck Plumbing Inc) in this trade, so that call works as written.

Before you rely on it

Same split as the electrical trades: PC is the company, MP and JP are the individuals. Colorado also licenses water conditioning separately (WC, WP, WI) for softeners and treatment systems, and those are in this API too.

What Department of Regulatory Agencies does not publish

• General contractors — Colorado does not license them at state level
• Street address
• Surety bond
• Workers' compensation
• General liability insurance
• The qualifying individual behind a licensed company

Full coverage detail, including the caveats that apply to every Colorado lookup, is on the Colorado page.
