Address Verification

Clean, standardize, & format U.S. and global addresses.

Approximately 20% of addresses entered online contain errors: spelling mistakes, wrong house numbers, incorrect postal codes, and sometimes formatting errors that don’t conform to a specific country’s postal regulations. This can be a big and costly concern for companies shipping across borders.

Melissa’s Global Address Verification service verifies addresses for 240+ countries and territories at point of entry and in batch to ensure only valid billing, shipping, and contact addresses are entered and used in your systems.

Access an engine certified using official governmental data^® addresslike CASS^™ for the USPS, SERP^™ for CanadaPost, PAF^™ for RoyalMail, and more.
Correct international addresses by adding missing components such as postal codes, locality, and more
Standardize addresses to meet local in-country formatting rules
Transliterate to and from native country languages and Latin
Add precise lat/long coordinatesup to the rooftop level.
