How it works

Matching made simple — the official transfer stays with USPS

PostSwap connects carriers who want to trade routes or positions. We handle discovery and conversation; you handle the paperwork through eReassign and official channels.

01

Post your route

Share your current location, craft, seniority, and what you’re looking for. Takes under a minute.

02

Browse & match

Explore the map or list. Filter by craft, city, or region until you find the right fit.

03

Chat via DM

Message matches directly. Confirm details, timelines, and expectations before you file.

04

File officially

Take your match through eReassign and USPS policy. We never process transfers ourselves.

Safety note: This platform is for matching only. All official transfers follow USPS rules and policies. Mutual swaps let everyone keep seniority and benefits!

Official guidance

USPS transfer & mutual exchange regulations

PostSwap helps you find a match — the Postal Service and your collective bargaining agreement govern the actual transfer. Always verify current rules with your installation, union, and eReassign.

Primary sources

Mutual exchanges are governed primarily by Employee and Labor Relations Manual (ELM) Section 351.6 (including 351.61), craft articles in the applicable National Agreement, and local installation-head approval. Voluntary reassignments often run through eReassign. This summary is educational only and is not legal or official USPS advice.

ELM 351.61

Mutual exchange — general policy

Career employees may exchange positions (subject to the appropriate collective bargaining agreement) if the officials in charge at both installations approve the exchange.

  • Exchanges must generally be between employees in positions at the same grade levels.
  • Approval is required at both installations — a match on PostSwap is not an approved transfer.
  • An exchange of positions does not always mean you automatically take over the other person’s exact duty assignment; local bidding and craft rules still apply.
Restrictions

Who may not exchange

Under ELM 351.61, the following exchanges are not permitted:

  • Part-time flexible (PTF) employees with full-time employees
  • Bargaining-unit employees with nonbargaining employees
  • Nonsupervisory employees with supervisory employees

Craft-specific MOUs can refine grade eligibility. For example, NALC MOU M-01646 treats city letter carrier grades CC-01 and CC-02 as the same grade solely for mutual exchange eligibility.

Seniority

What happens to seniority

Seniority in a mutual exchange is modified by craft contract language (e.g., city letter carriers under Article 41.2.E of the NALC National Agreement; similar provisions exist for other crafts such as APWU Articles 37 / 38 / 39).

  • Carriers often retain their seniority or take the seniority of the other employee, depending on the specific contract rule for that craft — commonly the junior of the two applies in many mutuals.
  • Duty assignments and routes may still need to follow local posting/bid procedures after the exchange.
  • Confirm seniority impact with your steward before filing.
eReassign

Voluntary reassignment path

If you are not doing a mutual exchange, voluntary transfers are commonly handled through eReassign (or written request to the installation head / HR where allowed).

  • Career employees typically must complete a lock-in period (often cited as 12 or 18 months depending on circumstance) before a voluntary eReassign is eligible — verify current rules for your craft and installation.
  • eReassign requests are usually active for a limited time (commonly one year) unless acted on sooner.
  • Residual vacancies, conversion ratios, and craft MOUs can affect how openings are filled.
Process

Practical steps after you match

  1. Confirm both parties meet ELM / craft eligibility (grade, career status, PTF vs FTR, etc.).
  2. Discuss timelines, stations, and expectations via DM — then move to official channels.
  3. Seek installation head approval at both ends and follow local HR instructions.
  4. File / process through eReassign or other official USPS procedures as directed.
  5. Keep your union steward in the loop for seniority, bidding, and grievances if needed.
Disclaimer

PostSwap’s role

PostSwap is a matching and messaging tool only. We do not approve transfers, change seniority, process eReassign applications, or act on behalf of the United States Postal Service.

  • Always use current ELM, National Agreement, JCAM / craft materials, and local management guidance.
  • Official references: ELM Section 350 (USPS) and your craft union resources (e.g. NALC, APWU).
  • Rules change — treat this page as a starting point, not a substitute for official documents.
