USPS Address Autocomplete API
As a developer, you want your users to enter their address as simply and easily as possible. You want them to get it right the first time so they can avoid delays in shipping and returns. And you want to know that the addresses you collect are accurate and deliverable so you can send invoices, receipts, confirmations, etc.
USPS has built a system that validates an address one-at-a-time through their web interface, but this isn’t a complete solution for you or your users. The USPS doesn’t provide you with a full database of valid addresses, and their API is limited in its functionality and uptime. They also have some restrictive terms of service, and they only offer a subset of their data.
A better alternative is to look for an address autocomplete api that uses a full address verification library and a robust set of data sources. Smarty’s US Autocomplete Pro is an API solution that allows you to send queries while a user types and instantly return address suggestions in a dropdown right under the cursor. This saves valuable screen space and eliminates errors that occur when a user hits the wrong key, misspells an entire word or forgets to include an important piece of information.
The top providers in the market for address autocomplete and validation APIs rely on a wide range of data sources to maintain accuracy, including USPS. But the specifics vary by provider: Melissa Data is known for its uptime and tech support, Loqate offers insanely accurate international data, and Smarty is fast, easy to use and provides comprehensive, up-to-date data for both US and international addresses.
