Nebraska to Oklahoma: master plumber license reciprocity
Nebraska does not issue a statewide master 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 master plumber or plumbing contractor (all states; no contractor reciprocity agreements)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
No state has a written plumbing contractor reciprocity agreement with Oklahoma, so every out-of-state master plumber or plumbing contractor uses the same route. Under OAC 158:30-9-1.4 a contractor-level applicant from a state without an agreement (or with only local licensing) may request exam equivalency; if the Board has previously approved that jurisdiction's exam, the technical trade section of the Oklahoma contractor exam is waived on a certified letter showing current good standing, the license category, a 70%+ exam score and no pending discipline, but 'the applicant for the contractor exam will still be required to take and pass the Oklahoma business and law section'. CIB does not publish the approved jurisdictions. Otherwise the applicant files the Application for Plumbing Examination with notarized experience affidavits and a copy of the out-of-state license, documents four years of verifiable plumbing experience (out-of-state hours count if lawfully obtained; a current out-of-state license may expedite processing), pays $330, and must pass both portions of the contractor exam through PSI with 75% each, completing the second portion within three years of approval. To activate the license the contractor files a $5,000 bond and $50,000 general liability insurance with CIB, or the Affidavit for Plumbing waiver if employed by a single entity.
Even where a written contractor agreement exists, OAC 158:30-5-4(e) grants only a journeyman license by reciprocity and requires the Oklahoma Plumbing Contractor Business and Law portion before the contractor license issues; since CIB publishes no plumbing contractor agreement with any state, no contractor reciprocity rows are recorded. Vendor claims of Oklahoma plumbing reciprocity with Texas, Colorado or Louisiana could not be confirmed from any CIB page.

How Oklahoma licenses master plumbers
Oklahoma master plumber · “Plumbing Contractor (Unlimited)”
Statewide license
Issued by Oklahoma Construction Industries Board (CIB), Plumbing Division
Oklahoma has no 'master plumber' title; its highest person-held plumbing credential is the Plumbing Contractor license, which CIB describes as 'the highest ranking plumbing license' and issues to an individual who passes the two-part contractor exam (technical trade and Plumbing Business and Law, 75% on each part, PSI, $92 per portion). This site maps the Unlimited Plumbing Contractor license to the master level. An applicant needs the journeyman qualifications plus one additional year, so four years (about 8,000 hours) of verifiable plumbing experience, and pays $330 ($30 application plus $300 initial license). After passing, the license is inactive until the contractor files a $5,000 corporate surety bond (or $5,000 cash or certificate of deposit) and a $50,000 commercial general liability certificate with CIB; only a licensed contractor may contract for plumbing work, and the licensee may operate as an individual, firm, LLC or corporation. CIB's Arkansas agreement covers journeymen only, so no state has contractor reciprocity with Oklahoma; out-of-state masters and contractors use exam equivalency where available or sit the full exam. Licenses renew annually ($200) with six hours of continuing education every 36 months.
Why Nebraska has nothing to transfer
Nebraska master plumber
Licensed by cities and counties
Nebraska issues no statewide master plumber or plumbing contractor license. The state licenses electricians only; a plumbing business must register with the Department of Labor under the Contractor Registration Act ($40 per year from August 1, 2026), which involves no exam and confers no trade competency. The master credential exists only in city ordinances: Omaha's Master Plumber (four years as an Omaha-licensed journeyman or equivalent standing in a comparable city, Plumbing Board exam, $10,000 bond and $1,000,000 liability insurance), Lincoln's Plumbing Master certificate (one year as a Lincoln journeyman or an engineering qualification, city exam, $250 Master Contractor registration and $500,000 insurance) and Grand Island's master plumber license. Neither Omaha nor Lincoln waives its examination for a master license from another state; Omaha accepts 'evidence of qualifying as a master plumber in a city of equivalent size that requires similar qualification criteria' as eligibility to test, and Lincoln admits any master or contractor licensed by examination elsewhere directly to its master exam without further qualifications. A contractor working in more than one Nebraska city needs a separate license in each plus the state registration.
How local licensing works in Nebraska
How local licensing works. There is no state plumbing board. The Contractor Registration Act requires every contracting business to register with the Department of Labor ($40 per year from August 1, 2026, workers' compensation certificate if there are employees), but the master plumber license that lets someone pull permits and run a plumbing business comes from each city's ordinance and examining board.
Omaha. The Master Plumber license is issued by the Plumbing Board under Omaha Municipal Code chapter 49. To sit the master exam (Sec. 49-231) an applicant shows one of: four consecutive years of experience installing plumbing systems while holding a journeyman license issued by the city; 'evidence of qualifying as a master plumber in a city of equivalent size that requires similar qualification criteria'; or, where the applicant's community requires no instruction for a license, a properly issued license or 12 consecutive years of experience (300+ hours each year, 21,000 hours total) at the Board's discretion. Applications are due by 9:00 AM on the 15th of March, June, September and December for exams in May, August, November and February; the master test fee is $81.00, and copies of all current or expired licenses plus notarized proof of employment hours are required. The master license costs $100.00 + $8.00 technology fee ('Exam Required') and renews for $75.00 + $6.00 with 8 continuing-education hours; before working as a contractor the master files a surety bond of at least $10,000.00 and liability insurance of at least $1,000,000.00 with [email protected]. Out-of-state treatment: an out-of-state or other-city master license can satisfy the eligibility requirement to test, but the Omaha exam is not waived and no reciprocity path is published for plumbers (Omaha's reciprocal-license process covers Building Contractor licenses only).
Lincoln. A Plumbing Master certificate requires holding a valid City of Lincoln Plumbing Journeyman certificate for at least one year, or a mechanical engineering degree from an accredited college plus two years of practical experience planning, laying out, supervising and installing plumbing equipment, or registration as a professional mechanical engineer in Nebraska, and passing the city exam (third Thursday of February, May, August and November; copper practical project plus a five-hour written exam on the 2018 UPC with Lincoln amendments and the Lincoln Gas Piping Code). Master exam filing fee $208. Annual registration: Plumbing Master Contractor $250 or non-contracting Master $75, renewed March 1-May 31 with 10 CEU hours; a lapse beyond 60 days revokes the license and requires retesting. A plumbing contractor also files a general liability certificate of at least $500,000 per occurrence naming the City of Lincoln as additional insured and listing the master plumber by name as an insured; a $5,000 bond is needed only for work in the city right-of-way. Out-of-state treatment: 'An applicant holding a valid Journeyman or Contractor/Master Plumbing License or Certificate, received by examination from another state or Municipal Governmental agency, shall be entitled to take the equivalent respective City of Lincoln Journeyman or Master examination without submitting any additional qualifications.' The one-year Lincoln journeyman prerequisite is bypassed; the exam is not.
Grand Island. Plumbing contracting companies must be licensed with the Building Services Division, and the individuals doing the work must hold a city master or journeyman license or apprentice registration and work under a licensed company. Exam and reciprocity applications are filed through the CitizenServe portal; the city publishes no thresholds, fees or accepted jurisdictions online, so contact Building Services at (308) 385-5444.
Bellevue and other cities license master plumbers and plumbing contractors under their own ordinances; Bellevue's Permits and Inspections documents page posts contractor testing information for plumbing contractors, but its requirements were not verified in this pass.
