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 isn't real, or there's incorrectly formatted data. We can still send to unverified addresses but it will cost $0.20 extra per addressee.
Address Verification checked with the USPS.
Address Verification Certified by the USPS. When you upload or feed your data into our system, we verify and reformat the address to match the USPS database.
Super fast
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.
