A verifier asset evaluates the accuracy and deliverability of address records. Use a verifier to determine the accuracy of input addresses, fix errors in addresses, and enhance addresses where possible with additional information.
You can also use a verifier to measure and report on the quality of each address, to retrieve global and country-specific enrichments for addresses, and to verify addresses to the certification standards that a country defines.
To evaluate and update input addresses, the verifier compares the input address data with address reference data. The Secure Agent downloads the reference data to the local system when the mapping runs.
You can enable a mapplet that contains a verifier asset transformation as an API. For more information about how to enable the mapplet, see Components.
