Enhanced Address Matching

When addresses are a little too shabby they must be corrected manually—a process that is painstakingly long and arduous. SmartyStreets US Address Verification works miracles. It deciphers, matches, and corrects even the shabbiest of addresses. Basically, it can handle most anything you throw at it.
Believe it or not, databases are packed with garbage addresses that other systems simply label as errors. But our enhanced address matching takes the toughest addresses and eats them for breakfast.

15+ Million Non-Postal Addresses

A physical address isn’t always the same as a mailing address. SmartyStreets validates 160 million USPS addresses plus over 15 million non-postal addresses. Go beyond validating only postal addresses and reach millions more!
