Wyoming to Minnesota: master plumber license reciprocity
Wyoming does not issue a statewide master plumber license, so there is nothing to transfer. Here is Minnesota'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 without a reciprocity agreement (exam required; equivalent license qualifies applicant to sit)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A master plumber licensed anywhere other than North Dakota or South Dakota gets no exam waiver and must pass the Minnesota master plumber written exam. The out-of-state license is itself the qualification to sit: DLI accepts 'a current master plumber license from another state where the requirements of the licensing jurisdiction are equivalent to those of Minnesota as determined by DLI' as one of the three master exam eligibility routes, alongside one year of experience as a licensed journeyworker plumber or a Minnesota restricted master license with five years as a contractor. DLI makes the equivalence determination case by case when it reviews the exam application. The applicant applies through iMS with the $50 exam fee, must wait 30 days to reapply after a failed attempt, and pays the license fee after passing; a master who intends to contract also needs the separate Plumbing Contractor license with bond and insurance. Minnesota has no separate law or business exam for individual plumbers.
DLI does not publish the criteria it uses to decide that another state's master requirements are 'equivalent'; a master whose state is found not equivalent would have to qualify through the journeyworker route (Minnesota journeyworker license held one year). Whether one year as a journeyworker licensed by another state satisfies the 'licensed journeyworker plumber' route was not confirmed from an official page. The initial license fee amount is not published on the pages fetched (Minn. Stat.

How Minnesota licenses master plumbers
Minnesota master plumber · “Master Plumber”
Statewide license
Issued by Minnesota Department of Labor and Industry (DLI), Plumbing Board
Minnesota issues a statewide, person-held Master Plumber license through DLI; the license 'authorizes the individual to perform plumbing statewide', and a separate Plumbing Contractor license (a business license that must have a licensed master plumber as its responsible individual and carry a bond, general liability and workers' compensation insurance under Minn. Stat. 326B.46) is not covered here. DLI also issues a Restricted Master Plumber license limited to cities and towns under 5,000. A new master applicant must pass DLI's written master plumber exam ($50 exam fee) and is eligible to sit it after at least one year of practical experience as a licensed journeyworker plumber, with a current master plumber license from another state whose requirements DLI determines are equivalent to Minnesota's, or with a Minnesota restricted master license plus five years in business as a plumbing contractor. Master plumbers licensed by examination in North Dakota or South Dakota may be licensed without the Minnesota exam. Licenses expire December 31 of odd-numbered years; renewal is $93 and requires 16 hours of continuing education, at least eight on the State Plumbing Code.
Why Wyoming has nothing to transfer
Wyoming master plumber
Licensed by cities and counties
Wyoming issues no master plumber or plumbing contractor license; the State Fire Marshal's electrical program is the only statewide trade licensing and it has no plumbing component. The master credential exists only in city ordinances: Cheyenne's Master (8,000 apprentice hours plus 6,000 journeyman hours and an ICC/NICET/NASCLA exam), Casper's Master Plumber (apprenticeship or four years plus five years as a journeyman or master, ICC G27-N), Laramie's master plumbing certificate of qualification (three years beyond journeyman, city exam), Gillette's Master Plumber (five years plus the ICC exam), Sheridan's Master Plumber (2018 ICC G27 with Gas) and Jackson's Master Certificate of Qualification (ICC G-series National Standard exam plus time in service). In every one of these cities a plumbing contractor must be or employ a master of record, and the contractor license is a separate business license with fees from $150 to $300 plus insurance or bond. No city accepts an out-of-state master license: Casper, Gillette and Jackson reciprocate only with other Wyoming jurisdictions, Sheridan refuses all outside licenses, Cheyenne's Board has undefined discretion, and Laramie may waive its exam for an equivalent certificate from any governmental agency. Rock Springs registers contractors for $125 with proof of insurance and tests nobody.
How local licensing works in Wyoming
How local licensing works. There is no state plumbing board; each city's ordinance defines its own master-level license and the plumbing contractor license it qualifies. The reciprocity statute the cities cite reaches only other Wyoming jurisdictions, and no city publishes a route that honours another state's master plumber or plumbing contractor license.
Cheyenne. A Master level craft employee license (12.1.8) requires 4 years/8,000 hours documented as an apprentice (or certified equivalent training) plus 3 years/6,000 hours documented as a journeyman and passing results on a current ICC, NICET or NASCLA exam from the Board's list. Fees are $50 application plus $50 initial and $25 renewal. A Plumbing (C1) contractor - covering plumbing and pipe-fitting systems other than fire sprinklers - may be licensed only if it always employs a full-time master or qualified supervisor of that class, who may represent only one contractor (13.0); the C1 tested contractor license costs $50 application plus $200 initial and $75 renewal. Reciprocity is at the Board's discretion (3.3.2/3.5.1) with no published partner list and a statute limiting it to Wyoming jurisdictions.
Casper. Master Plumber ($75 new, $37.50 renewal) requires a federally recognized plumbing apprenticeship or four years in a Casper-licensed plumbing shop plus five years as a journeyman or master plumber in a Casper-licensed shop, and proof of passing ICC G27-N or equivalent. A Plumbing Contractor license ($300/$150) covers any plumbing work including steam and water boilers, must be backed by a full-time licensed master plumber, and requires $250,000/$500,000/$250,000 liability insurance. Reciprocal Master/Journeyman licenses ($50/$25) are limited to holders of a current license from another Wyoming jurisdiction with comparable testing.
Laramie. A master plumbing certificate of qualification requires three years as a journeyman (Table 15.24.020-1) and the building official's examination ($5 per attempt), or is issued without exam on presentation of a certificate from another governmental agency whose exam the board of examiners finds at least equal. All plumbing contractor work must be performed by or under the supervision of a master plumbing certificate holder, who must be available to the building official within 24 hours. The Plumbing Contractor license costs $300 new and $35 renewal and requires a business location and telephone, a $500,000 combined single limit insurance certificate naming the City and a Wyoming Workers' Compensation certificate of good standing; licenses and certificates run January 1 - December 31.
Gillette. Master Plumber ($50 new, $50 renewal) requires five years of approved experience and passing ICC examination results. A Class D Plumbing Contractor ($150/$50) works under the 2024 IPC, may not do gas pipefitting on its plumbing license, and must designate a Master of Record - a full-time employee or owner licensed as a Master Plumber, able to reach any job site within 48 hours and replaced within 60 days if they leave. Reciprocity (5-III-1(d)) is limited to active, good-standing licenses from other Wyoming local governments, with testing waived on proof of the ICC plumbing or contractor exam and no fee charged.
Sheridan. Master Plumber ($50 new, $50 annual) acts as Master of Record for a plumbing company, must show they meet the Plumbing Contractor requirements (2018 ICC G27 exam, four-year journeyman plumber verification on Form JP, two-year project verification on Form A) and pass the 2018 ICC G27 Master Plumber with Gas exam. The Plumbing Contractor license ($200 new, $200 annual) also needs a $1,000,000 liability insurance certificate and a $10,000 license and permit bond, and every plumbing business must hold both a contractor license and a Master of Record. The City does not accept licenses from other cities, towns, counties or states.
Jackson. The Master Certificate of Qualification card is the prerequisite for a Plumbing Contractor license and is the only individual card the Town still issues. It is obtained by passing the ICC National Standard trades exam through Pearson VUE (only G-series tests based on the 2018 I-Codes are accepted) and meeting the time-in-service requirement in JMC 15.36.050, or by reciprocity for someone 'currently licensed and in good standing in a Wyoming jurisdiction that meets our licensing requirements'. Applications go through the SmartGov portal with a 30-day processing window; the contractor license then requires the bond and insurance in JMC 15.36.035 and renews every December 31, while the Master COQ card renews triennially with six hours of ICC-accredited continuing education. Licensing covers only work inside Town limits.
Rock Springs. Contractors register with the Building Inspection Office ($125 fee and a certificate of insurance naming the City) before working; no master license or exam exists.
