Title: ZIP Codes erased from ZIP field
Edited: July 1, 2008
If your USPS Database is expired or AccuZIP6 cannot link to the USPS Database, the Validation process might delete the ZIP codes out of your ZIP field. Here are some tips that will help you fix this:

If you have received a new update from AccuZIP Inc, install it immediately, or at your earliest convenience. The USPS expires their USPS Database 105 days after creating it, making it possible for the USPS Database to expire a couple days before the end of the month.

If you notice, after importing and validating your list, that your ZIP Codes are missing, install the latest AccuZIP6 DVD. Launch AccuZIP6, then validate your list again.

Your ZIP Codes will be filled in and your addresses will be validated successfully.
