Which OR classifications count as plumbers

• PB — Plumbing Contractor 1,392 records
• JP — Journeyman Plumber 4,239 records
• WHI — Water Heater Installer 228 records
• WTI — Water Treatment Installer 25 records

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/OR/PB3668" \
  -H "X-RapidAPI-Key: YOUR_KEY" \
  -H "X-RapidAPI-Host: contractor-license-verification2.p.rapidapi.com"

PB3668 is a real OR licence (REESE PLUMBING LLC) in this trade, so that call works as written.

Before you rely on it

PB is the business licence and the one to verify before you hire. Journeyman, water heater and water treatment licences are individual and do not authorise contracting. As with the electrical trades, this register holds active licences only — a miss means “not currently licensed”, not “never licensed”.

What Construction Contractors Board does not publish

• A status column of its own
• Disciplinary actions

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