Mississippi to New Mexico: journeyman plumber license reciprocity
Mississippi does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is New Mexico'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 (all states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
No state has a plumbing journeyman reciprocity agreement with New Mexico. The RLD Construction Industries page and the 2025 PSI journeyman application both state that the only reciprocated journeyman classification is EE-98J (electrical), and 14.6.4 NMAC contains no general endorsement provision, only an expedited path for military service members, spouses, dependents and veterans certified in another jurisdiction. A plumber licensed elsewhere therefore applies exactly like a new candidate: a notarized Journeyman Certificate Application to PSI with $75 for the JP classification (or $75 for JPG, which covers both plumbing and gas fitting), notarized Mechanical/Plumbing Work Experience Affidavits from employers or supervisors covering two years (4,000 hours) within the past ten years, then the JP written exam (70 questions, open book on the 2021 Uniform Plumbing Code and 2015 New Mexico Plumbing Code) and the JP practical exam. Experience from another state counts if it was gained while employed by a contractor licensed in the trade or was legal work in the state where it was performed; the out-of-state license itself is not a substitute for the affidavits. New Mexico has no separate law exam for journeymen; state code and rule questions are part of the trade exam. All requirements must be met within six months of the application or the fee is forfeited.
Verified against the current RLD page and the 2025 PSI application: no plumbing reciprocity partners are named (Texas and Utah appear only in the electrical EE-98J context, and Utah is not even on that list). Accredited technical training or apprenticeship classroom time counts as one-half year of experience per year, capped at half of the requirement (14.6.4.8(C)). 14.5.5.9 NMAC still lists a $25 mechanical journeyman exam fee and $25 per-year renewal fee; PSI currently charges $68.88 per exam, so the renewal amount should be confirmed with PSI at renewal time. Applying for JP and JG separately costs $150; JPG covers both for one $75 fee.

How New Mexico licenses journeyman plumbers
New Mexico journeyman plumber · “JP Journeyman Plumber (certificate of competence)”
Statewide license
New Mexico requires every individual doing plumbing work to hold a Construction Industries Division (CID) journeyman certificate of competence; the JP Journeyman Plumber certificate is the plumbing journeyman credential, and the JPG Journeyman Plumber and Natural Gas Fitter certificate adds natural gas piping (JG and JPF cover gas fitting and pipe fitting alone). A JP applicant needs two years (4,000 hours) of plumbing experience within the last ten years, files a notarized application and work-experience affidavits with PSI for $75 per classification, and must pass the open-book JP written exam and a hands-on practical exam, each at 75%. Certificates run for three years and JP, JPG, JG and JPF holders complete 16 hours of continuing education (eight on the enforced code) before each renewal. CID reciprocates only the EE-98J electrical journeyman classification, so an out-of-state plumbing license earns no exam waiver, although out-of-state hours count toward the experience requirement. A journeyman may work only while employed by a contractor licensed in the classification (MM-1 or MM-98 for a JP).
Why Mississippi has nothing to transfer
Mississippi journeyman plumber
Licensed by cities and counties
Mississippi does not issue a journeyman plumber license. The Mississippi State Board of Contractors (MSBOC) licenses contracting businesses - commercial contractors and subcontractors on jobs over $50,000 and residential contractors and residential plumbing subcontractors above the residential thresholds - through a Certificate of Responsibility held by the company with a tested qualifying party, and its FAQ states that it does not license individual journeymen; none of its Plumbing, Mechanical or Residential Plumbing classifications, exams or reciprocity agreements apply to a plumber who only wants to work for an employer. Individual plumbers are licensed, where they are licensed at all, by cities under their own ordinances: Southaven's Building Department issues apprentice, journeyman and master trade licenses and accepts a current journeyman license from another jurisdiction or a passed ICC journeyman exam in place of its own testing, while coastal cities such as Gulfport license only the contractor's qualifying party and have no journeyman card. An out-of-state journeyman plumber license therefore has no state-level recognition in Mississippi; the plumber must check the ordinance of each city where they will work and apply locally, and Southaven-style acceptance of another jurisdiction's card or an ICC score is the closest thing to reciprocity that exists.
How local licensing works in Mississippi
How local licensing works. Mississippi's contractor law (Miss. Code Title 31 ch. 3 for commercial work, Title 73 ch. 59 for residential work) is enforced by MSBOC at the business level: a commercial license is required for every contractor and subcontractor on commercial jobs over $50,000, and residential plumbing subcontractors need a residential license on new homes over $50,000 or remodels over $10,000. Those licenses attach to the company and its qualifying party, not to journeymen, and no statute standardizes city trade cards. Journeyman licensing is a municipal matter and varies by city; many cities have no journeyman card at all and simply require plumbers to work under a licensed contractor.
Southaven. The Building Department's Application for License covers Apprentice ($20), Journeyman ($50) and Master ($100) trade licenses. A journeyman applicant files the application with photo ID and either a copy of a current, active journeyman license held in another jurisdiction or written proof of passing the ICC journeyman exam; no Southaven exam is given, so an out-of-state journeyman card or ICC plumbing score substitutes for local testing. The city refers all questions about out-of-state reciprocity to MSBOC. There is no journeyman license; plumbers work under the licensed contractor.
Jackson, Hattiesburg, Biloxi, Tupelo. These cities license contractors and, in some cases, trades under their own ordinances, but no official page publishing a journeyman plumber card could be opened in this pass: the Jackson contractor-licensing URL redirected to a map embed and the Hattiesburg plumbing ordinance PDF returned 404. In practice a journeyman card from another jurisdiction or a passing ICC journeyman plumbing score is accepted by Southaven, and elsewhere the plumber simply works under a locally licensed contractor.
