Postal Address Verification Service for Businesses

Postal address verification is done to ensure that all the addresses in a database are valid and deliverable. It is a process of comparing addresses with the official database of the USPS and other trusted data sources. Initially, the addresses are parsed and standardized as per the standard format. If an address is found, it is cross-checked to verify whether all the details are correct. However, an address that is not found is declared invalid. Most of the time, the address is found but is incorrect. Postal address verification services help to correct all the details as per the USPS guidelines and make the addresses mail-ready.

PostGrid’s address verification services are meant to validate and verify all your addresses at either point-of-entry or through processing your mailing lists.

Businesses face many issues like bad data and failed deliveries, causing tarnished brand image, wasted time, and high shipping costs. These problems can be solved by using address verification services.
