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.

Global Address Verification provides industry-leading power, speed, and ease of use to quickly verify any address around the world.

Melissa's address verification solutions empower organizations to standardize, correct and validate any U.S. address in one step. The U.S. address correction engine is CASS Certified™ by the USPS® and includes DPV® (Delivery Point Validation), LACSLink®(Locatable Address Correction System), RBDI (Residential/Business Delivery Indicator), SuiteLink™, and eLOT®(enhanced Line of Travel).

Melissa started as a US mailing company in 1985. This gives us decades of experience with the ins and outs of the many patterns people use in writing addresses, the common mistakes made, and evolution of the mail stream. We are a long standing USPS CASS Certified™.

We leverage DPV® (Delivery Point Validation), LACSLink®(Locatable Address Correction System), SuiteLink™, and eLOT®(enhanced Line of Travel) from the USPS.

We have also developed our own priority data for RBDI (Residential vs Business Delivery Indicator), AddressPlus (residential apartment append), 5+ million non-USPS addresses, and our own address identifier that is persistence through time and zip code changes called MAK.

Faced with the challenge of working with addresses in foreign languages like Russian, Greek, Chinese, or Japanese? Melissa Global Address supports many different language sets and can transform non-Latin writing systems into Latin characters so addresses can be easily validated.

Our engine allows you to verify and correct addresses in a single country or in all countries across the world, all from a single interface. We have done all the hard work on combining the varied addressing systems across the world so that all you have to do to verify an address in a new country is to send it in.

Our engine gives you the address back as:

  • Formatted in the standard set by the postal authority in mailing label or in database storage format.
  • The Parsed address fields like house number, thoroughfare, locality, postal code for categorization and analysis

We support multiple language scripts, including:

  • Cyrillic (Russia)
  • Hellenic (Greece)
  • Hebrew (Israel)
  • Arabic (United Arab Emirates)
  • Kanji (Japan)
  • Chinese (China)
  • Hangul (South Korea)
  • Thai (Thailand)
Our engine will allow you to transliterate between these scripts and latin so you can store your address data in the preferred format.
