Understanding Postal Codes

You can use the Postal Code Revisions program (P0117) to set up postal codes. The system stores the postal codes in the Postal Codes (F0017) and Postal Code Address (F0118) tables. By accessing the data in these tables, you can enter a postal code and have the system return a city, state, and county to the Address Book Revisions program. To enter postal codes for address book records, you must first set processing options for the Address Book Revision program.

To revise a postal code, you must delete the postal code on the Work with Postal Codes form and then read the code.
