Delivery Point Validation^TM

Ensure your mail pieces will actually go somewhere!

Perhaps one of the most important and beneficial features of Qualified Address Certified Scrubbing and the LiveAddress API is the ability to determine which addresses are undeliverable or do not exist.

Our service will match an address to a range of house numbers on a street as well as validate each element of the address using certified USPS® Delivery Point Validation™.

How It Works

Our DPV™ matches up the addresses you submit to an official USPS® database of valid delivery addresses. Any addresses that don't match are considered "undeliverable" and you will be notified in the results.
