On the Manage customers window you can associate a mail code with a customer’s address. The Mail Code field is an optional, special-purpose field that comes into play for bulk mailings, such as subscription mailing. The field provides special groupings within a mailing. The Mail Code field allows a higher-level sort for ZIP-sorted labels and printouts. With this feature, you can segregate all first-class mail recipients at the end of a label run by giving the first-class records a consistent mail code, while leaving the regular mail records uncoded.
The Mail Code field displays on the Manage customers window once you create the MAIL_CODE general lookup/validation table. You can specify how the field displays by enabling an Address Code on the Customer Setup – Address and Notes window (from Customers, select Set up module> General, and click Address and Notes). The Mail Code field displays on the main address tab only when you enable the Single Mail Code option and on all three primary address tabs when you enable the Multiple Mail Codes option.

Sample customer record with Mail Code field
To define the MAIL_CODE lookup table
Before you can associate a mail code with a customer’s address, you need to create the MAIL_CODE general lookup/validation table.
1. From Customers, select Set up tables > General lookup/validation to open the Set up general lookup/validation window.
2. Select (New Table) from the list of available tables.
3. Enter the name of the new table in the space provided.
4. Click Save.
5. Click New.
6. Enter a Code.
Note: Make sure the Code you specify for a mail code does not exceed the maximum field length for the MAIL_CODE field (5 characters). If the length of the Code field is greater than the defined field length, the value will not display in the drop-down as an available option.
7. (optional) Enter a Description.
8. Click Save.
9. Repeat the process to enter additional codes.
