Mailing Standards of the United States Postal Service,
International Mail Manual
August 7, 2017
Mailing Standards of the United States Postal Service, International Mail Manual (IMM) provides our official prices and standards for all international mailing services. Many mailers find it helpful to reference these standards as they prepare and deposit their mail.
Mailers looking for an overview of prices and international extra services can use Notice 123, Price List. It provides the most commonly sought international mailing information in an easy-to-read and easy-to-find format. Notice 123 is available on our Postal Explorer Web site at pe.usps.com. The Postal Explorer Web site also provides helpful search features, mailing tools, and price calculators to make mailing easy.
Summary of Changes
The IMM is updated frequently on Postal Explorer at pe.usps.com. The Summary of Changes section in the IMM notes revisions by IMM chapter, subchapter, part, section, or Individual Country Listing (ICL). Mailing standards in the IMM are revised by notices published in the Postal Bulletin or the Federal Register.
Availability
The current edition of the IMM and also archived editions back to 2001 are available in PDF and HTML formats on the Postal Explorer Web site at pe.usps.com.
