Free · Address verification API

Verified addresses,
auto-filled.

The Maiaddy API is free to use, and it does one thing well: it calls up addresses for verification. Add a loccode field to your address form, and let your customers pick their exact address from a dropdown instead of typing it out.

How it works

A customer enters their street's loccode into your address field.
The API returns every address registered on that street.
They select their specific address from the dropdown.
Your form auto-fills with a verified, standardized address, no manual entry, no ambiguity.
