Validate, Standardise, Cleanse, and Format UK and Global Addresses in Real-Time

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.

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

  • Leverage a postal certified address engine using official government data including CASS (USPS), SERP (Canada Post), PAF (Royal Mail) and more
  • Correct international addresses by adding missing components such as postal codes, locality, and more
  • Standardise addresses to meet local in-country formatting rules
  • Transliterate to and from native country languages and Latin
  • Add precise lat/long coordinates up to the rooftop (delivery point) level
