Address Verification – US, Canada and International Postal Validation | Melissa

Clean, Standardize and Format U.S. and Global Addresses

Approximately 20% of addresses entered online contain errors - spelling mistakes, wrong house numbers, incorrect postal codes, formatting errors that don’t comply with a country’s postal regulations. This can result in late or undeliverable shipments, a big and costly concern for companies doing business domestically and across borders.

  • Correct international addresses by adding missing components such as postal codes, locality, and more
  • Standardize addresses to meet local in-country formatting rules
