Plumber License from North Carolina to New Hampshire: Does It Transfer? (2026)
Does New Hampshire accept a North Carolina plumbing license?
A plumbing license transfers from North Carolina 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 North Carolina license, and meet New Hampshire's endorsement requirements. New Hampshire deems North Carolina plumbing licenses equivalent and usually waives its plumbing exam for them, which is what this endorsement application relies on. 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.

Verdict
Licensure by endorsement
North Carolina is on New Hampshire's list of qualifying jurisdictions for licensure by endorsement — states New Hampshire deems equivalent, which is not a reciprocity agreement. A journeyman plumber licensed in North Carolina, active and in good standing, applies to the New Hampshire Office of Professional Licensure and Certification (OPLC) — Mechanical Safety and Licensing Board by endorsement, usually without its plumbing exam.
What's different between North Carolina and New Hampshire
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into New Hampshire. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
North Carolina to New Hampshire (this page): Licensure by endorsement.
New Hampshire to North Carolina (the reverse move): Licensure by endorsement.
The route is the same in both directions.
- Does coming from North Carolina matter?
North Carolina gets New Hampshire's most common result: 41 of 50 origins (the other 49 states and DC) get the same one, so for most movers the origin does not change the answer.
The others get: no state license to transfer (9).
- Application fee
New Hampshire lists $190–$210 for an out-of-state applicant and North Carolina lists $30–$150 for the reverse move; neither may be the full cost.
- Processing time
North Carolina lists 4–6 weeks for the reverse move; New Hampshire has no verified processing-time figure on file, so the two cannot be compared here.
- Exam rules on record
New Hampshire and North Carolina carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- New Hampshire (this move): 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
- North Carolina (the reverse move): North Carolina has no license reciprocity; every applicant must meet the NC experience requirement and pass the NC business/law exam section. Under a Technical Examination Waiver Agreement it waives ONLY the technical exam section for South Carolina plumbing contractors who passed the SC technical exam (SC Residential Plumbing maps to NC Plumbing Class II; SC Commercial Mechanical Plumbing (PB) maps to NC Plumbing Class I). Separately, under G.S. 87-21(g) the Board may, at its discretion, license an out-of-state contractor of the same or equivalent class without written examination if its standards are found substantially equivalent.

Frequently asked questions
Can I keep my North Carolina plumbing license after I'm licensed in New Hampshire?
Yes — plumbing licenses in different jurisdictions run independently. Keep the North Carolina credential active on its own renewal and continuing-education schedule and you hold both, which is common for plumbers working near a state line.
