Address verification.

Let us check if your address data is real.

All we need is the first line of the address and postcode 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 Royal Mail.

When you upload or feed your data into our system, we verify and reformat the address to match the Royal Mail Postal Address File (PAF).

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.

Address verification API

We know automation is important so our address verification is available via our REST API. Simply post the address to our endpoint and receive instant verification. Learn more with our API documentation.
