IMM Issue 37 June 7, 2010
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. Postal Explorer also provides helpful search features, mailing tools, and price calculators to make mailing easy.
