SUPPLEMENTARY INFORMATION:

On September 12, 2025, the Postal Service published a notice of proposed rulemaking (90 FR 44153-44155) to retire the manifest
mailing system (MMS). In response to the proposed rule, the Postal Service received one formal comment. The comment and response
are as follows:

Comment: The comment was generally in agreement with retiring the manifest mailing system, however, the commentor questioned whether
some smaller businesses may face challenges with the technology transition.

Response: The Postal Service has taken proactive steps to support these customers through the Intelligent Mail® for Small Business Tool
(IMsb). The IMsb Tool is a free, web-based application designed specifically for small business mailers. It requires no software
installation or downloads, making it accessible to businesses with limited technical resources. The tool generates unique
Intelligent Mail barcodes (IMb) for use on address labels and mail pieces, and it features a simple, step-by-step interface
that guides users through the process. Additional benefits include easy access via standard web browsers (e.g., Google Chrome), no need for specialized software or technical expertise, and is a cost-effective solution for businesses with
limited budgets. For further guidance, users can refer to the IMsb User Guide, located on the IMsb Tool landing page, available
on PostalPro at https://postalpro.usps.com. This tool represents a meaningful step toward ensuring that small businesses are not left behind in the Postal Service modernization
efforts.

The Postal Service is retiring the manifest mailing system, by retiring manifest mail preparation along with the hard copy
documentation. The Postal Service is migrating customers to Electronic Documentation (eDoc), Full Service, Seamless, and eInduction,
for Letters, Cards and Flats. Options for Package customers are USPS Ship and Click-N-Ship. Mailers of Letters, Cards, and
Flats can reference Mail.dat/Mail.XML Technical Specifications posted on PostalPro. Package shippers can reference Publication
199, Publication 205, and USPS Ship documentation on PostalPro.

As a result of retiring MMS, Publication 401, Guide to the Manifest Mailing System, will no longer be available on PostalPro after the effective date.
