Summary of Changes

Mailing Standards of the United States Postal Service,
International Mail Manual

Issued July 14, 2024

This Summary of Changes to Mailing Standards of the United States Postal Service, International Mail Manual (IMM^®) includes revisions that have become effective during the previous 12 calendar months.

In chapters 1–9 and in “Country Price Groups and Weight Limits” of this online version of the IMM, change bars (vertical lines in the margin) indicate that Postal Bulletin updates have been incorporated in the adjacent text (note that the change bars appear only in the PDF version, and only for revisions that have become effective in the current calendar year, not for all the previous 12 months). However, in the individual country listings (ICLs) of this online IMM, change bars do not appear even though Postal Bulletin updates have been incorporated in the ICL text.
