Missouri to Arkansas: journeyman plumber license reciprocity
Missouri does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is Arkansas's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Out-of-state journeyman plumber without a reciprocity agreement (all states except Oklahoma)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
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.

How Arkansas licenses journeyman plumbers

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.
Why Missouri has nothing to transfer
Missouri journeyman plumber
Licensed by cities and counties
Missouri has no statewide journeyman plumber license and no state plumbing board. RSMo chapter 341 instead authorizes cities over 15,000 population and first-classification counties to examine and certify plumbers through their own boards of examiners, and the Division of Professional Registration licenses no plumbing profession (the state's only statewide construction credential is the voluntary electrical contractor license). Journeyman plumbers are therefore licensed jurisdiction by jurisdiction: St. Louis County's Board of Plumbing Examiners, the City of St. Louis Plumbers and Drainlayers Board of Examiners, Kansas City's City Planning and Development contractor-licensing program, Springfield's Building Development Services, and other cities and counties that have adopted a plumbing code. There is no statewide reciprocity and no state mechanism to recognize an out-of-state license. Springfield admits an applicant licensed elsewhere on proof of experience plus an identical ICC (Pearson Vue), Prometric, Experior or Block exam score of 75% or better, and Kansas City may accept a comparable exam from another jurisdiction it deems equivalent; the St. Louis County and City of St.
How local licensing works in Missouri
How local licensing works. Missouri regulates plumbers only through local government. RSMo §§ 341.010-341.080 (cities over 15,000) require plumbers to hold a certificate issued after examination by a city board of examiners, and §§ 341.090-341.220 (first-classification counties) let a county create a department and board of plumbing and sewer inspection that licenses master plumbers, journeymen and drainlayers, sets fees and license terms (§ 341.180) and requires master plumber bonds (§ 341.200). Each board writes its own rules, so hours, exams, fees and the treatment of other jurisdictions' licenses differ from place to place, and a plumber must hold the license of each jurisdiction in which they work.
St. Louis County. The Department of Transportation and Public Works' Plumbing Licensing office (41 South Central Avenue, Clayton, 314-615-3741, [email protected]) licenses Journeyman, Master Plumber and Apprentice plumbers and certifies plumbing contractors under the county plumbing code. The Board of Plumbing Examiners normally meets the first Thursday of each month at 8:00 a.m., and renewal carries a PEU (professional education unit) requirement. The county's separate mechanical board exempts pipefitting and sprinkler-fitting journeymen 'licensed under the county plumbing code' from its own test, which shows how tightly the county's trade licenses are tied to its own code.
City of St. Louis. The Building Division's Plumbers and Drainlayers Board of Examiners 'reviews licensing matters, apprentice applications, complaints, and other business related to plumbing and drainlaying work in the City of St. Louis'. Certification requires an application with notarized references and a passing score from a recognized agency such as Prometric or ICC ($60 application, first four-year certificate free, $181 renewal every four years), and the city 'may accept comparable examinations from other jurisdictions if deemed equivalent or superior' to its approved exams. Kansas City does not publish online whether it still issues a separately titled journeyman plumber license, its experience requirement, or any named reciprocity (for example with Johnson County, Kansas); contact the city's permits office.
Springfield. Building Development Services certifies Journeyman Plumbers. Eligibility is 4 years under the supervision of a master plumber or 6 years' experience in the trade, documented on signed, notarized Applicant Experience Forms for every employer (Schedule C or 1099s if self-employed). The packet goes to the board, which meets the first Thursday of each month at 5:00 p.m. in the Busch Building; approval to test is good for one year. The exam is the ICC plumbing exam through Pearson Vue (about $125 paid to Pearson Vue), 75% to pass; the city then issues the Trade Certification Card for $25, renewing at $25 per year. Out-of-state treatment: an applicant licensed in another jurisdiction applies under 'Reciprocity from another jurisdiction' by submitting the same experience documentation plus a copy of an exam score notification of 75% or better from Prometric, Experior, Block or ICC (Pearson Vue), 'the examination must be the identical exam as required by the City of Springfield'; the exam is then not repeated. A license backed by a different exam gives no advantage beyond documenting experience.
