IMM Revision: Editorial Corrections

Effective November 2, 2015, the Postal Service™ will revise Mailing Standards of the United States Postal Service, International Mail Manual (IMM®) to incorporate some minor editorial revisions.

These revisions do not revise content but only correct editorial mistakes such as misspellings, missing words, improper punctuation, improper cross references, and formatting. The following are examples of some of the revisions we have made:

n Update the list of registered marks and trademarks in part 116.

n Correct the formatting in 261.1 (improper break between items in the list) and 541.121 and 541.2 (revising the list from numbers to letters).

n Standardize the formatting in mailing addresses by omitting most punctuation, per the preferred format noted in Publication 28, Postal Addressing Standards.

Because these revisions are only editorial in nature (not substantive), we are not marking the text with “change bars” (the vertical lines in the margin of the PDF files to indicate revised text).

We will incorporate these revisions into the next update of the online IMM, which is available via Postal Explorer® at http://pe.usps.com.
