Five-Digit ZIP Product, in conjunction with City State Product, provides mailers the ability to add 5-digit ZIP Codes to address files and validate existing 5-digit ZIP Code™ assignments.

Five-Digit ZIP Product contains 5-digit ZIP Codes and detailed, ranged street data only for cities with more than one delivery ZIP Code (i.e., multi-coded cities). A complete list of ZIP Codes for both single- and multi-coded cities can only be found in City State Product. Both City State Product and Five-Digit ZIP Product are required to perform complete 5-digit ZIP encoding and validation.

Five-Digit ZIP Product is available on cartridge and CD-ROM, and updates are produced monthly or bimonthly. Technical guides are shipped free of charge with a subscription to this product and are also available upon request.

A sample Five-Digit ZIP file is available for download.
