A verifier verifies the address data to fix errors and to complete partial address records. To fix an address, the transformation looks for a positive match with an address in the reference data. The transformation replaces any incorrect or absent data elements in the input address with the correct elements in the address reference data.

You can configure a verifier to format the output address data to meet the requirements that the local postal authorities specify. You can also configure a verifier to create an output address in a structure that suits your project or data structure requirements.

A verifier can provide you with a list of address suggestions from which you can select the most relevant address. The address list includes the best matches between the input address and the reference data.

A verifier can measure the quality of an address and help you to understand and analyze the results of the verification process. You select the fields that contain the address status information when you configure the output address structure.

A verifier can provide additional information as enrichments to help you better understand and use your address data. You can configure a verifier to provide enrichments that are specific to addresses in individual countries or enrichments that apply to every country. You can also configure a verifier to add geocoordinates as an enrichment to verified addresses.

Postal certification is an additional level of address verification and standardization in Australia, Canada, France, New Zealand, and the United States. Certification requires that a software application validates address accuracy and prepares address records in accordance with the format and quality levels that the national postal carriers expect. The verification engine in Data Quality performs address verification in accordance with the latest certification standards.
