Append Missing ZIP Code Data

Fill the holes in your address data

Out of all the components of a mailing address, the ZIP code is one of the most essential. Incomplete ZIP code data will lead to significant problems down the road and will disqualify you for postage discounts.

SmartyStreets scrubbing products and LiveAddress web service will add the missing ZIP code data and even append the +4 codes to help qualify for discounts by the USPS® on your mailing which speeds delivery of mail by one to two days.

If a ZIP code is already in the address data but is not correct, valid, or complete, our services will automatically fix the address.

Requirements

In order to append ZIP code data, our scrubbing services require some kind of street address as well as a city and state.
