Address Verification
Clean, standardise & format international 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.
- We host the cloud service and provide updates on a regular basis as well as new reference data that you can automatically access at any time .
- 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 level.
How Address Verification Works
1 Capture
Autocompletes and/or verifies an address at point of entry so bad data never enters your system.
2 Parse
Uses proprietary lexicons & rules to parse an address into its component parts.
3 Standardise
Conforms an address to local country format.
4 Verify
Uses authoritative, in-country reference datasets to check the validity & deliverability of a physical address.
5 Transliterate
Transforms foreign languages into Latin characters so an address can easily be validated.
6 Output
A clean, deliverable address ready for mailing, order fulfilment, or analytics.
