Verdict
Reciprocity agreement
North Carolina is on New Hampshire's reciprocity list, which puts this move on the streamlined track — on two conditions. Your North Carolina license must have been earned by examination, not grandfathered in, and be active and in good standing; where it is, New Hampshire waives its journeyman exam and the requirements below are what it still insists 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. One caution: these agreements are directional and revocable.
