What is Address Validation?

The Trulioo Address Validation Service corrects the address for countries all over the world. It adds missing components such as region or city, it formats the address to local country standards, corrects small typos and it validates the address exists in the country to the level of unit, building, street, city, or postal code.

When requested, Validation Codes can be returned by the service in the Verify API response to indicate when a value has been modified along with appending the address values returned by the service.
In the Trulioo Platform API-Direct Portal, the 3000 Validation Code is also provided which indicates what level the service was able to validate the given address:

Fully Validated to unit
Fully Validated to building
Partially Validated to building
Partially Validated to street
Partially Validated to city
Partially Validated to state/province
Address Corrected

Benefits

Increased match rates
