New Hampshire to Arkansas: master plumber license reciprocity
Arkansas has no reciprocity agreement with New Hampshire. A New Hampshire master plumber applies by endorsement.

Out-of-state master plumber or plumbing contractor (all states; no master-level agreements)
The board reviews your out-of-state credentials case by case. Some exam is usually still required, often only a law or code exam.
No state has a master-level plumbing reciprocity agreement with Arkansas; the Oklahoma agreement is journeyman-only and Oklahoma's board states there is 'no contractor reciprocity'. An out-of-state master plumber or plumbing contractor therefore applies to the Plumbing and Natural Gas Section for the Master Plumber examination, documenting at least one year of work as a licensed journeyman and five years of total plumbing experience; time worked under the out-of-state journeyman or master license counts once the origin board verifies the license, exam history and standing. The applicant sits the Arkansas master plumber examination (written, on the Arkansas Plumbing Code; no separate business-and-law exam), pays the Section's exam and license fees, and renews annually. Ark. Code Ann. § 17-1-108 obliges the Section to grant automatic licensure to a holder of a substantially similar master-level license in good standing, subject to any Arkansas-specific exam it still requires, so applicants from IPC-based exam states should ask the Section whether the trade exam is waived. Commercial plumbing contracting above the Arkansas Contractors Licensing Board thresholds also needs a separate contractor's license from that board.
The one-year-as-journeyman and five-years-total figures are from general knowledge of Ark. Code Ann. § 17-38-30x and must be re-verified. Whether Arkansas accepts an out-of-state journeyman license as satisfying the 'licensed journeyman' year, or requires an Arkansas journeyman license first, is not confirmed; an Oklahoma unlimited journeyman can obtain the Arkansas journeyman license under the 2024 agreement without the exam and then qualify for master by examination. The Section's treatment of § 17-1-108 automatic licensure for master plumbers is unknown; examTradeRequired is set true as the conservative reading.

Statewide license
Issued by Arkansas Department of Health, Plumbing and Natural Gas Section (Committee of Plumbing Examiners)
The Master Plumber license is Arkansas's highest person-held plumbing credential, issued statewide by the Department of Health's Plumbing and Natural Gas Section under Ark. Code Ann. § 17-38-301 et seq. A master plumber may contract for and supervise plumbing work and is the license under which journeymen and registered apprentices work; a plumbing business must operate under a licensed master. An applicant must have worked at least one year as a licensed journeyman plumber and have five years of total experience in the trade, then pass the Section's written master plumber examination on the Arkansas Plumbing Code. Arkansas's only signed plumbing reciprocity agreement, with Oklahoma (effective October 21, 2024), covers the journeyman license only, so every out-of-state master plumber or plumbing contractor qualifies by experience verification and examination. Fees and continuing-education hours could not be confirmed because the Section's pages were unreachable during this review.
