To reflect U.S. Postal Service® ZIP® Code realignment efforts, ZIPMove data files were created to assist address-matching software in providing up-to-date, accurate ZIP + 4® codes. The ZIPMove Product is available with monthly or bimonthly updates on CD-ROM. 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.
A sample ZIPMove file is available for download.
