Iowa to Arkansas: journeyman plumber license reciprocity
Arkansas has no reciprocity agreement with Iowa. A Iowa journeyman plumber applies by endorsement.

Out-of-state journeyman plumber without a reciprocity agreement (all states except Oklahoma)
The board reviews your out-of-state credentials case by case. Some exam is usually still required, often only a law or code exam.
A journeyman licensed in a state other than Oklahoma applies to the Plumbing and Natural Gas Section as a new journeyman candidate, documenting at least four years of plumbing experience; verified out-of-state apprenticeship and journeyman work counts toward that requirement, and the Section asks the origin licensing board to verify the license, exam history and any discipline. Absent an agreement the applicant sits the Arkansas journeyman plumbing examination, a written exam on the Arkansas Plumbing Code administered by the Section; Arkansas has no separate business-and-law exam for journeymen. Under Ark. Code Ann. § 17-1-108 the Section must grant automatic licensure to a holder of a substantially similar license in good standing who passed that state's exam, subject to any Arkansas-specific examination the Section still requires, so an applicant from a state with a comparable IPC-based exam should ask the Section whether the trade exam is waived. The applicant pays the Section's examination and license fees and thereafter renews annually.
The Department's rules say examinations are not required for reciprocal licensure when the other jurisdiction's license is substantially similar, meaning that jurisdiction has adopted a national model plumbing or gas code and uses a comprehensive exam created and proctored by a national examination agency or equivalent. Whether your exam qualifies is decided by the Committee of Plumbing Examiners on your application, so ask the Section at 501-661-2642. The Department's plumbing page also lists signed reciprocity agreements with Texas and Louisiana; applicants from those states should ask the Section for the agreement terms.

Statewide license
Issued by Arkansas Department of Health, Plumbing and Natural Gas Section (Committee of Plumbing Examiners)
Arkansas licenses plumbers statewide through the Department of Health's Plumbing and Natural Gas Section under the Arkansas Plumbing Law (Ark. Code Ann. § 17-38-101 et seq.), with the Committee of Plumbing Examiners setting qualifications and exams. The Journeyman Plumber license is issued to an individual who has completed four years as a registered apprentice under a licensed master plumber (or equivalent verified experience) and passed the Section's written journeyman examination, which covers the Arkansas Plumbing Code (an IPC-based code), the Arkansas Fuel Gas Code and the plumbing law; natural gas piping is part of the plumber license, and gas fitter licenses are separate restricted credentials. Licenses expire each December 31 and renew annually. Out-of-state applicants are handled by the Section case by case; the Department's plumbing page also lists signed reciprocity agreements with Oklahoma (journeymen, effective October 21, 2024), Ohio (master plumbers), Texas and Louisiana.
