Pennsylvania to Oklahoma: journeyman plumber license reciprocity
Pennsylvania does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is Oklahoma'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 plumbing journeyman without a reciprocity agreement (all states except Arkansas)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A journeyman from any state other than Arkansas has no reciprocity route, because CIB publishes only the Arkansas plumbing agreement and OAC 158:30-5-4 requires a written agreement for the specific license sought. Under OAC 158:30-9-1.4 a journeyman from a state without an agreement, or from a jurisdiction with only local licensing, may request exam equivalency; if the Board has previously approved that jurisdiction's exam as substantially similar, the Oklahoma journeyman exam is waived on a certified letter from the licensing jurisdiction showing a current license in good standing, the license category, an exam score of 70% or higher and no pending discipline. CIB does not publish which jurisdictions' exams have been approved, and no equivalency form exists on the Plumbing Forms page. Otherwise the applicant files the Application for Plumbing Examination with notarized experience affidavits and a copy of the out-of-state license, which 'may expedite processing of the requirements' (OAC 158:30-9-1(k)(3)); out-of-state experience lawfully obtained counts toward the three-year requirement. The applicant pays $75 and must pass the Oklahoma plumbing journeyman exam through PSI with 75%. Oklahoma has no separate law exam for journeymen.
Some private websites say Oklahoma has plumbing reciprocity with Texas, Colorado and Louisiana. CIB lists no such agreements: its only plumbing reciprocity agreement and application are for Arkansas, so applicants from those states use this route. Colorado's Plumbing Board has no reciprocal agreements with any state. CIB does not publish which jurisdictions' exams it has approved for equivalency; ask the Plumbing Division at (405) 521-6550. The exam pass mark is 75% under OAC 158:30-9-1(d), but the equivalency letter only needs a home-state score of 70% or higher. The journeyman exam is based on the 2018 International Plumbing Code and International Fuel Gas Code with Oklahoma revisions; either the 2018 or the 2024 editions may be used from October 8, 2026 through January 8, 2027, and only the 2024 editions from January 9, 2027.

How Oklahoma licenses journeyman plumbers
Oklahoma journeyman plumber · “Unlimited Plumbing Journeyman”
Statewide license
Issued by Oklahoma Construction Industries Board (CIB), Plumbing Division
Oklahoma issues statewide plumbing journeyman licenses through the Construction Industries Board (CIB) under the Plumbing License Law of 1955 and OAC Title 158, Chapter 30, in Unlimited and Residential categories. An Unlimited Plumbing Journeyman applicant must be 18 and show three years of verifiable experience in the plumbing trade while employed by a licensed plumbing contractor (about 2,000 hours per year, so roughly 6,000 hours; Oklahoma hours count only while registered as an apprentice), or equivalent U.S. military experience, with a Committee-approved 1,000-hour program substituting for two years and a 500-hour program for one year. The applicant pays $75 ($25 application plus $50 initial license), and must score 75% on the Oklahoma plumbing journeyman exam administered by PSI ($92 per portion). CIB has one published plumbing reciprocity agreement, with Arkansas (effective October 21, 2024, journeyman only); other out-of-state journeymen may seek exam equivalency if the Board has approved their jurisdiction's exam, and a current out-of-state license otherwise expedites processing of the experience requirement. Journeymen must work under a licensed plumbing contractor, renew annually ($75) and complete six hours of continuing education every 36 months.
Why Pennsylvania has nothing to transfer
Pennsylvania journeyman plumber · “Journeyman Plumber (city-issued; no state license)”
Licensed by cities and counties
Pennsylvania has no statewide plumber license at the journeyman level: none of the Department of State's 29 professional licensing boards covers plumbers or plumbing contractors (the only construction-related board is Crane Operators), and there is no Commonwealth journeyman or master plumber credential. Individual licensing exists only where a city ordinance creates it. Philadelphia's Department of Licenses and Inspections, advised by the Plumbing Advisory Board, issues a Journeyman Plumber License (Philadelphia Code Title 9-1003) that authorizes plumbing work under a licensed master plumber but not running a business: four years as a Philadelphia-registered apprentice (or a similar authorization from another state or local jurisdiction with equal or greater requirements, subject to L&I approval), the ICC Journeyman Plumber Examination referencing the current Philadelphia Code or applied within 12 months of passing, and a $126 annual fee ($25 of that is the non-refundable application fee). Allentown posts 2026 journeyman and master plumber exam applications and licenses the plumbing trade separately from a business license. Scranton's published form is a master electrical/mechanical/plumbing/general contractor application with no journeyman plumber form on that page. There is no state-level reciprocity; Philadelphia's other-jurisdiction clause substitutes for local apprentice registration only and does not waive the ICC exam.
How local licensing works in Pennsylvania
How local licensing works. Pennsylvania does not license plumbers. Each city that licenses the trade does so under its own ordinance through L&I, a plumbing board, or a codes office. Residential plumbing contractors doing $5,000 or more of home-improvement work in a year must also register with the Pennsylvania Attorney General under the Home Improvement Consumer Protection Act; that registration is not a trade license and involves no exam.
Philadelphia (verified). L&I issues Plumber Apprentice, Journeyman Plumber and Master Plumber licenses (trade-license list). The journeyman page, last updated with the Plumbing Advisory Board, is the only plumbing service page opened in full. Scope: drainage, cesspools, traps, waste vents, water piping, and fixtures attached to plumbing elements, excluding gas or electric heaters; work must be under a licensed master plumber; the card does not authorize operating a business. Experience: registered Philadelphia apprentice for a minimum of four years, or proof of a similar authorization from any other state or local jurisdiction with equal or greater qualification requirements, subject to L&I approval. Exam: ICC Journeyman Plumber Examination; must reference the current Philadelphia Code and associated standards, or the application must be filed within 12 months of passing. Photo: 2 in. × 2 in. color. Fees: $126 license ($25 non-refundable application fee applied to that amount; balance due on approval); $126 annual renewal; 1.5% of the license fee per month if more than 60 days late. Apply via eCLIPSE or in person at 1401 JFK Blvd. (Permit and License Center). PLI issues person-held trade licenses in other trades; plumbing exam, fee, experience and whether a journeyman tier exists were not verified. Do not assume Pittsburgh waives a plumber exam.
Allentown. Building Standards and Safety licenses electrical, plumbing and sheet metal trades. Operating a contracting company requires both a trades license and a city business license. No reciprocity language appears on the trades-licensing page. In Philadelphia, document four years (local apprentice or equivalent out-of-jurisdiction authorization) and pass the ICC Journeyman Plumber Examination on the Philadelphia Code (or apply within 12 months of that exam). Elsewhere, expect a separate city application and usually a local or ICC exam. Statewide reciprocity: none.
