Install an address reference data file for each country that the source address data identifies. A country that has a large population might require multiple files. In addition, you can install data files that supplement or enrich the address data. The mail carrier can use the data enrichments to certify the accuracy of the addresses and to accelerate mail delivery.

When you perform address validation, the Address Validator transformation compares each input record to the address reference data. If the transformation finds the input address in the address reference data, the transformation can update the record with the correct and complete address data. If you purchased additional reference data sets, the transformation can also enrich the address data.

window in the Developer tool to view information about the address reference data files on the Informatica services machine in the domain.
