Mississippi to Connecticut: master plumber license reciprocity
Mississippi does not issue a statewide master plumber license, so there is nothing to transfer. Here is Connecticut'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.
Contractor (P-1) by equivalent out-of-state license (all states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A master plumber or plumbing contractor licensed in any other state applies under DCP's 'Plumbing Contractor - Equivalent Out of State License' path. DCP reviews a single out-of-state license for equivalency to the P-1: the hours table requires 576 classroom hours matching Exhibit A and 12,000 on-the-job hours (8,000 plus two years / 4,000 as a licensed journeyperson). The applicant submits a copy of the license, official license verification, the laws and regulations that set the requirements met to obtain it, and the scope of work, with the non-refundable $150 application fee. If approved, CGS 20-333 and 20-334a(a)(1) still require the Connecticut contractor examination before the $150 initial license is issued—the origin license does not waive the trade exam. An applicant whose license is not found equivalent is not approved on this path and must document comparable journeyman service and training instead (CGS 20-334a(a)(1)(A)). No named reciprocal partners appear on the plumbing contractor out-of-state page.
CLASSROOM-HOUR CONFLICT on the contractor out-of-state page: the example sentence says a P-1 equivalent license 'must have required 720 classroom hours and 12,000 hours of on the job training', while the hours table on the same page lists P-1 classroom hours as 576 (with 12,000 OJT). CE, reinstatement and the annual expiration month live on the unfetched Plumbing-and-Pipefitting-Licensing hub.

How Connecticut licenses master plumbers
Connecticut master plumber · “P-1 Unlimited Plumbing Contractor”
Statewide license
Issued by Connecticut Department of Consumer Protection, Occupational and Professional Licensing
Connecticut has no license titled 'master plumber'; the top-tier personal credential is the P-1 Unlimited Plumbing Contractor, issued by DCP to an individual and permitting all plumbing and piping work under CGS 20-330 (permits and contracting with the public). Limited contractor classes cover narrower scopes (J-1, J-3, P-7, P-9, PP-1, SP-1). A new P-1 applicant needs two years as an unlimited licensed journeyperson or equivalent experience and training; the out-of-state equivalency table is 12,000 OJT hours (8,000 plus two years / 4,000) and 576 classroom hours matching Exhibit A. CGS 20-334a(a)(1)(A) lets out-of-state journeyman service count if DCP finds it comparable, and still requires the contractor examination. CGS 20-333a would allow an exam waiver only if the origin state reciprocates; the P-1 out-of-state page names no partners. Fees are a $150 application fee and a $150 initial/renewal license fee; licenses expire annually.
Why Mississippi has nothing to transfer
Mississippi master plumber
Licensed by cities and counties
Mississippi does not issue a personal master plumber license. The state-level plumbing credential is the Mississippi State Board of Contractors (MSBOC) contractor license: the commercial Mechanical major classification or its 'Plumbing (Test Required)' specialty (required on commercial jobs over $50,000; application and renewal $400, $300,000/$600,000 liability insurance, CPA-reviewed financial statement showing $50,000 net worth for Mechanical or $20,000 for the Plumbing specialty) or Residential Plumbing / Residential Mechanical (required for residential plumbing subcontracting over $10,000 in remodeling or $50,000 new construction; application $50, renewal $100). The license is issued to the business through a Certificate of Responsibility with a named qualifying party who passes the open-book PSI Plumbing (or Residential Plumbing) trade exam and the mandatory Mississippi Law and Business Management exam, so a master plumber who only wants to work for an employer has nothing to transfer to at the state level; the personal master credential exists only in cities such as Southaven (Master trade license, $100, which itself requires an active MSBOC license, a $10,000 bond and liability insurance) and Gulfport (contractor license issued to the qualifying party, $100). MSBOC waives its plumbing trade exam, for $50 per exam, for qualifying parties who hold a current license obtained by examination from the Alabama Plumbers and Gas Fitters Examining Board (commercial Plumbing exam only), the Ohio Construction Industry Licensing Board (Plumbing), the South Carolina Residential Builders Commission (Residential Plumbing, no discipline in three years) or the Tennessee Board for Licensing Contractors (all exams, no discipline in the last year); the Alabama General Contractors Board, Arkansas and Louisiana agreements expressly exclude plumbing, and the Business and Law exam is never waived.
How local licensing works in Mississippi
State contractor license (business). MSBOC issues commercial and residential contractor licenses to companies through a Certificate of Responsibility. The commercial Mechanical major classification 'involves all aspects of heating, cooling, refrigeration and associated equipment piping and ductwork as well as plumbing work' and carries 15 specialties including Plumbing, Process Piping, Underground Utilities, Fueling Systems and Irrigation Systems (all test required); an applicant may instead take only the Plumbing specialty. The qualifying party (owner, officer or responsible managing employee) passes the PSI open-book trade exam and the Mississippi Law and Business Management exam; fees are $400 application ($400 annual renewal, $100 per additional classification), general liability insurance of $300,000 per occurrence / $600,000 aggregate, and a CPA-reviewed financial statement showing net worth of $50,000 for a major classification or $20,000 for a specialty. Residential Plumbing (Residential Plumbing exam) and Residential Mechanical (Residential HVAC and Residential Plumbing exams) require the Law and Business exam, a $50 application fee ($100 per additional classification, $100 renewal) and proof of liability insurance with no minimum.
MSBOC exam waivers for out-of-state qualifying parties. Reciprocity 'applies to waiver of a trade exam requirement only' ($50 per exam waived, plus a $25 verification fee) after the origin board completes MSBOC's Reciprocity Verification Form; the applicant must have held the origin license for one year and passed that board's exam. Plumbing waivers are available for the Alabama Plumbers and Gas Fitters Examining Board (commercial Plumbing exam only; current license, Alabama exam taken), Ohio CILB (Plumbing; no discipline in the last year), the South Carolina Residential Builders Commission (Residential Plumbing; no discipline in three years) and Tennessee ('the only state that waives Mechanical and Plumbing'; no discipline in the last year). The Alabama General Contractors Board entry waives 'all exams but Mechanical & Plumbing', Arkansas excludes 'any type of Mechanical (i.e. Plumbing, Boilers, Process Piping, HVAC)', and Louisiana 'CAN WAIVE HVAC BUT NOT MECHANICAL OR PLUMBING'; Georgia, North Carolina, the South Carolina Contractors Licensing Board, Florida and California agreements do not reach plumbing. Separately, Form UROL under the Universal Recognition of Occupational Licenses Act (Miss. Code 73-50-2) waives the trade exam for an individual who has established Mississippi residency and held a similar license in any state for at least one year, and the Military Family Freedom Act (73-50-1) applies to military members and families. Every path still requires the Business and Law exam and full application review.
Southaven. Master trade license $100: application, photo ID of the license qualifier, certificate of liability insurance, a $10,000 general surety bond in favor of the city, an active MSBOC contractor's license certificate and the company EIN. An out-of-state applicant without an MSBOC license must provide a letter of good standing from a municipality where their license is active and may not take residential projects or commercial projects over $50,000; reciprocity questions are referred to MSBOC. Confirmed for mechanical and electrical on 2026-09-15; the plumbing card was not separately confirmed because the form could not be reopened on 2026-09-16.
Gulfport. Contractor license issued to the qualifying party ($100, waived with an MSBOC Certificate of Responsibility): notarized application, current MSBOC license if any, five reference letters (waived with an MSBOC license), $100,000/$300,000 liability insurance naming the city, home-jurisdiction privilege license and photo ID. No reciprocity provision.
