A. Explanation. The only change since the June 2020 edition is Section 238.1, which discusses the current addressing standards for overseas military addresses.
B. Purpose. Jointly developed by the Postal Service™ and mailing industry, standardized address information enhances the processing and delivery of mail, reduces undeliverable-as-addressed mail, and provides mutual cost reduction opportunities through improved efficiency. The standards include the uniform methods for matching addresses with the information in Address Information System (AIS) products and formats for outputting addresses on mailpieces. This document describes both standardized address formats and content — format describes how the various elements appear on a mailpiece or in an address record, and content describes the characters that constitute the various address elements. This document also outlines the guidelines that govern how address information appears in the AIS products.
C. Summary of Changes. Effective November 30, 2022, Section 238.1 is revised to reflect the current addressing standards for overseas military addresses.
