To reduce undeliverable-as-addressed (UAA) mail, the U.S. Postal Service has developed a new data table to use in conjunction with address matching software that should help mailers determine when they may be sending to vacant addresses.

The new “no-stat” and “vacant” tables are available through Coding Accuracy Support System address matching software as part of the USPS’s Delivery Point Validation product. The tables are simple to use and can help mailers save on production and postage costs by reducing UAA mail, according to the USPS. If an address is flagged as vacant, the recommended course of action is to remove that address from the mailing until it becomes occupied again.
