Who is affected and how:

• United States Postal Service: Must follow new procedural steps for major, nationwide service changes — prepare and submit proposals to the Postal Regulatory Commission, create and maintain detailed storefront notices, and allow time for the PRC advisory process. This creates additional administrative tasks and minor operational costs (notice production, staff time) but does not change funding.

• Postal Regulatory Commission: Gains a clear statutory advisory role for nationwide or substantially nationwide Postal Service changes. The PRC will need to review submissions and issue advisory opinions within its existing processes; no specific statutory deadline for PRC response is created.

• Postal customers and the public: Will receive more advance information about major service changes through PRC notices and storefront postings, improving transparency and the ability to track and respond to service changes that affect mail delivery or retail services nationwide.

• Retail postal facility staff and local communities served by affected storefronts: Will be responsible for posting and maintaining notices for the required period, increasing local-level communications duties.

Overall impact: The legislation strengthens transparency and administrative review for large-scale Postal Service changes, likely causing modest administrative burdens for the Postal Service and postal retail locations while improving public notice and PRC oversight. It does not appropriate funds or create new programs, nor does it mandate actions by states, local governments, or private third parties beyond the posting requirement at Postal Service retail locations.
