Last verified: 2026-07-21 · source: New Hampshire Office of Professional Licensure and Certification (OPLC) — Mechanical Safety and Licensing Board ↗
A plumbing license transfers from Pennsylvania to New Hampshire by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the New Hampshire Office of Professional Licensure and Certification (OPLC) — Mechanical Safety and Licensing Board, verify your Pennsylvania license, and meet New Hampshire's endorsement requirements. New Hampshire licenses a journeyman plumber by endorsement — without requiring its own plumbing examination — when the applicant holds an active, good-standing journeyman plumber license from one of 33 'qualifying jurisdictions' whose requirements OPLC deems substantially similar (RSA 310:17 / HB 594, rule Plc 313.34); applicants from any other state must qualify through New Hampshire's apprenticeship route and pass the New Hampshire plumbing examination.
