Provides mailers the information necessary to create an application that would facilitate frequent and cost-effective processing for updating very large computerized mailing lists for automation compatibility and improved deliverability.
In cooperation with the mailing industry, the U.S. Postal Service® designedZ4Change to provide mailers the information to create an application that would facilitate frequent and cost-effective processing for updating very large computerized mailing lists for automation compatibility and improved deliverability. This joint effort promotes the Industry/USPS® Worksharing Task Force goal of increased use of automation for mail processing. This product contains raw data and does not contain any software. Z4Change is available through Electronic Product Fulfillment (EPF).
Current USPS regulations require that all customer address lists be processed by CASS Certified™ address-matching software (see DMM® 708.3.3) for a complete description of CASS™ requirements. CASS Certified software applies the correct ZIP + 4®, delivery point, and/or carrier route codes while standardizing the address, city, and state elements. To enhance deliverability, the USPS recommends that customers reprocess their address lists more frequently using CASS Certified software; however, frequent reprocessing of address lists can be costly and time-consuming.
Z4Change was developed for customers who need data as a cost-effective means of improving the deliverability of their mail using the most current ZIP + 4 and delivery point information. Z4Change helps customers achieve this goal by providing data that indicates which ZIP + 4 Codes have been realigned in the past twelve months. When a highrise ("H") or firm ("F") record is added to the ZIP + 4 Product by the USPS, Z4Change also shows a transaction for the supporting street ZIP + 4 Code, allowing customers the opportunity to upgrade previously coded street-level matches. Customers must then develop their own software to access Z4Change to determine which records on their address lists need to be reprocessed by CASS Certified software. As a result, only records that have had transactions will need to be reprocessed, which can be done on a monthly or bimonthly basis.
Should the USPS determine that a significant change in CASS requirements warrants a complete update of all addresses, Z4Change customers may be notified that they will be required to reprocess their entire address lists. Otherwise, Z4Change customers will only be required to reprocess their entire lists at the end of the third year following Z4Change certification.
Z4Change Product and CASS certification offer the following benefits:
Eliminates the need to reprocess an entire address list by providing a means of maintaining continuous qualification for discounted automation rates. Z4Change users' address files remain current and in compliance with USPS regulations.
Increases address accuracy by enabling more frequent ZIP + 4 address file processing.
Enhances the mailer's competitiveness in the marketplace by improving the deliverability of mail and increasing the promptness of mail delivery.
A base reference file that can be accessed by an application to assign the correct ZIP + 4 Code associated with a physical address.
The ZIP + 4 Product File enables businesses with computer capabilities to add ZIP + 4 codes to their address files. The ZIP + 4 file contains approximately 30 million records is available in its entirety or by selected states. Mailers must purchase or develop their own matching software in order to use this file.
The ZIP + 4 file is available through Electronic Product Fulfillment (EPF) on a monthly or quarterly basis. The changed ZIP + 4 Code information is available monthly. The ZIP + 4 product contains raw data and does not contain any software.
To convert mailing lists to ZIP + 4, mailers can...
Order an electronic ZIP + 4 database from the United States Postal Service® and develop their own address-matching software.
Lease or purchase software from an outside vendor and convert their own lists.
Subcontract their conversion through a service bureau.
A sample ZIP + 4 file is available for download.

ZIPMove Product
A means of correcting addresses that have undergone a ZIP Code realignment in which a change in city name and finance number occurred.
To reflect U.S. Postal Service® ZIP® Code realignment efforts, ZIPMove data files were created to assist address-matching software in providing up-todate, accurate ZIP + 4® codes. The ZIPMove Product is available with monthly or bimonthly updates through Electronic Product Fulfillment (EPF). This product contains raw data and does not contain any software.
The primary objective in creating this product was to maximize mailers' ZIP + 4 code matching potential in situations in which ZIP Code realignments have taken place and a change in city name and/or finance number has occurred (which normally prevents address-matching software from determining the newly assigned ZIP Code).
Mailers are encouraged to incorporate ZIPMove as a regular part of their address hygiene process for the purpose of correcting addresses that have undergone a ZIP Code realignment in which a change in city name and/or finance number occurred.
