CAAS
Certified Address Verification

Let us check if your address data is real.

As a CASS certified direct mail platform all we need is the first line of the address and Zip code to check verify your addresses in real time! If any addresses are not verified it could mean address not real, or there's incorrectly formatted data. We can still send to unverified addresses but it will cost $0.20 extra per addressee.

Our engineers have built the address verification service using modern technology in a way to make sure it is lightning fast and completely on demand. This means you get instant results to find out if the address is deliverable or not.
