Plumber License from Pennsylvania to Montana: Does It Transfer? (2026)

Last verified: 2026-07-21 · source: Montana Board of Plumbers — Department of Labor and Industry, Business Standards Division ↗

A plumbing license transfers from Pennsylvania to Montana by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the Montana Board of Plumbers — Department of Labor and Industry, Business Standards Division, verify your Pennsylvania license, and meet Montana's endorsement requirements. Montana waives its journeyman written and practical examinations for an applicant who took and passed both the written and practical journeyman exams in Oregon, Idaho, North Dakota, or South Dakota and holds an active license there with no complaints filed; every other out-of-state applicant must sit for the Montana journeyman written and practical exams.

Verdict

Licensure by endorsement

Pennsylvania is not among the states Montana names for an automatic exam waiver, so this move runs on the Montana Board of Plumbers — Department of Labor and Industry, Business Standards Division's individual endorsement or equivalency review rather than a guarantee. Montana waives its journeyman written and practical examinations for an applicant who took and passed both the written and practical journeyman exams in Oregon, Idaho, North Dakota, or South Dakota and holds an active license there with no complaints filed; every other out-of-state applicant must sit for the Montana journeyman written and practical exams. Bring your Pennsylvania license, proof that it is active and in good standing, and your apprenticeship and exam records — and get any discretionary exam or experience credit in writing before you rely on it.
