Pennsylvania to Massachusetts: master plumber license reciprocity
Pennsylvania does not issue a statewide master plumber license, so there is nothing to transfer. Here is Massachusetts'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.
Master by examination (all states; exam not waived)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
An out-of-state master plumber cannot have the Massachusetts master examination waived. M.G.L. c. 142, § 4 requires the examiners to examine each person desiring to engage in the business of a master plumber, and no Board page lists a written reciprocal agreement. Local permits and bonding still apply after licensure (M.G.L. c. 142, § 3).
No Reciprocity row: unlike electricians (M.G.L. c. 141, § 2B and 237 CMR 15.00, NH only), Chapter 142 has no 'license without examination' statute.

How Massachusetts licenses master plumbers
Massachusetts master plumber · “Master Plumber”
Statewide license
Massachusetts issues a statewide Master Plumber license through the Board of State Examiners of Plumbers and Gas Fitters. M.G.L. c. 142, § 3 requires a master plumber's license to engage in the business as a master plumber; the master license must be displayed in the place of business, and advertising must show the designation and license number. A licensed master plumber may carry on gas-fitting work throughout the commonwealth, subject to local permits and bonding. Under § 4 the examiners must examine each applicant for a master plumber's license; the statute has no reciprocity or exam-waiver provision.
Why Pennsylvania has nothing to transfer

Licensed by cities and counties
Pennsylvania issues no statewide master plumber or plumbing-contractor licence; none of the Department of State's 29 boards covers the trade, so the master-level credential exists only in cities that have chosen to license it. Allentown posts a 2026 Master Plumber Exam Application and requires a separate business licence to contract. Harrisburg posts a plumbing licence application whose master-versus-journeyman split was not verified. Pittsburgh's plumbing trade-licence page 404'd. There is no state-level recognition of an out-of-state master plumber licence and no municipal programme verified here that waives the plumbing trade exam. An arriving master should expect to apply city by city, document local experience thresholds, and sit each city's exam (ICC or city-written) unless that city later publishes an exam-waiver rule.
How local licensing works in Pennsylvania
How local licensing works. With no state plumbing board, each Pennsylvania city that licenses master plumbers does so under its own ordinance. The journeyman card, where it exists, does not authorise pulling permits or running a shop; the master (or master-contractor) licence does. A master licence is valid only in the issuing city. The journeyman page states that a journeyman works 'under a licensed master plumber' and may not operate a business, which implies the master licence is the contracting credential. Other PLI trade licences are issued to individuals, expire 365 days from issue, and (for electrical and mechanical) accept ICC master exams for any code year plus a stated experience total; whether plumbing follows that pattern is unverified. 2025 plumbing licence fee unknown.
Allentown. 2026 Master Plumber Exam Application is posted under Professional Trades Licensing. Contracting requires the trades licence and a city business licence. Reciprocity not mentioned on the landing page. Electrical Option B on that same form (eight years in lieu of exam) must not be assumed to apply to plumbing.
Inbound master. No Pennsylvania state licence and no verified exam-waiver reciprocity. Plan on a new application in each city where permits will be pulled. Philadelphia is the most fully documented shop: obtain the Master Plumber's License after (typically) holding or qualifying beyond the journeyman ICC path; confirm current master fees and exam on the master service page before applying. Allentown requires its master plumber exam application plus a business licence. Scranton uses the 2021 master contractor packet. Statewide reciprocity: none.
