Transfer Your Plumber License to Oklahoma: Reciprocity & Endorsement (2026)

Last verified: 2026-07-21 · source: Oklahoma Construction Industries Board (CIB) — Plumbing Division ↗

Oklahoma has bilateral plumbing reciprocity with 1 state (Arkansas): a plumber originally licensed by examination in one of them can skip Oklahoma's journeyman exam. Oklahoma waives its journeyman plumbing exam only for applicants who hold an unlimited plumbing journeyman (or higher) Arkansas license obtained by Arkansas examination and held at least one year in good standing, under the Oklahoma-Arkansas reciprocity agreement effective 2024-10-21; all other out-of-state plumbers must qualify with three years of experience (or an approved education substitution) and pass the Oklahoma journeyman exam. Everyone else applies as a new journeyman applicant. Fee: $75 (Arkansas reciprocal application total $75.00 ($50 license fee + $25 application processing fee). Non-reciprocal applicants pay a separate journeyman application fee and a third-party exam fee.).

Verdict

Reciprocity with 1 states

Read Oklahoma's reciprocity as a named list, and the list is the rule: if you were licensed by examination in a state on it and your license is in good standing, the streamlined track below applies; if not, no amount of field experience substitutes for Oklahoma's exam. Two cautions. The agreement is directional — it describes the states Oklahoma recognizes, which tells you nothing about the reverse move — and it typically excludes licenses that were grandfathered in rather than earned by examination. Confirm both against the Oklahoma Construction Industries Board (CIB) — Plumbing Division before you rely on the waiver.

Oklahoma's only plumbing reciprocity agreement is with Arkansas (effective 2024-10-21); it covers the unlimited journeyman class and higher and waives the journeyman exam for Arkansas licensees who passed the Arkansas exam by examination. Oklahoma CIB rules (OAC Title 158, Chapter 30) require a written state-to-state reciprocity agreement, so a license from any state lacking such an agreement cannot transfer and the holder must qualify as a new applicant. Aggregator claims of reciprocity with Texas, Kansas or New Mexico are not supported by the CIB's own pages. No national plumber verification database exists; use the CIB license lookup.
