Montana to North Carolina: master plumber license reciprocity
North Carolina has no reciprocity agreement with Montana. Your Montana experience counts toward eligibility, but you must pass the North Carolina exam.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Out-of-state master plumber or plumbing contractor without a waiver (all other states)
Nothing is waived, but your documented out-of-state hours count toward eligibility to sit the exam.
The Board's Applicant Information page states there are no license reciprocity agreements with any other state and that every applicant must meet North Carolina experience requirements and complete the applicable examinations, except the South Carolina technical-exam waiver and Neighbor State License Recognition for NC residents. G.S. 87-21(g) lets the Board license out-of-state plumbing contractors without written examination after finding qualifications substantially equivalent, but the Board has not published partner states other than the SC technical waiver. An inbound master plumber or plumbing contractor from any other state therefore applies to sit the examination: 4,000 hours of on-site installation, maintenance, service or repair of plumbing systems (up to 2,000 hours academic or technical training), which may have been earned in any state. After approval (currently about six weeks) the candidate takes the technical portion and the North Carolina business and law portion, then files the License Activation Form and fee within 45 days of passing. City or county journeyman or master cards are not a substitute for a state plumbing-contractor license.
PSI is named in the HVAC extract as the scheduler; the Applicant Information page says only 'exam provider' and lists seven NC testing centers. Separate application per classification. Restricted Limited Plumbing Contractor is a different exam (1,500 hours) and is not this path.

Statewide license
Issued by North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors
North Carolina has no license titled master plumber. Its highest plumbing credential is the person-held Plumbing Contractor license issued by the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors under G.S. The individual who passes the two-part examination (technical plus business and law) is the licensee, may list the license in a firm name, and pays an annual license fee after activation. A first-time applicant needs 4,000 hours of on-site plumbing experience (up to half academic or technical training), and out-of-state hours are accepted. The Board states it has no license reciprocity with any state; the only technical-exam waiver is with South Carolina (NC business-law exam still required). North Carolina residents licensed in Georgia, South Carolina, Tennessee, Virginia or West Virginia may seek licensure without examination under the Neighbor State License Recognition Act (G.S. 93B-15.3). Restricted Limited Plumbing Contractor (1,500 hours, 2-inch and smaller exterior water/sewer/irrigation backflow) is a narrower contracting class, not a master equivalent.
