2 Postal Addressing Standards

21 General

211 Standardized Delivery Address Line and Last Line

The Delivery Address Line and the Last Line of addresses output to the mailpiece should be complete, standardized, and validated with the ZIP+4 file and City State file, respectively.

The Postal Service defines a complete address as one that has all the address elements necessary to allow an exact match with the current Postal Service ZIP+4 and City State files to obtain the finest level of ZIP+4 and delivery point codes for the delivery address. A complete address may be required on mail at some automation rates. See the DMM for more detailed information.

A standardized address is one that includes all required address elements and that uses the Postal Service standard abbreviations (as shown in this publication or in the current Postal Service ZIP+4 file).
