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.

Leverage decades of experience in US Addressing

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.
