USPS Address Data Updates

How often the address database is updated

Our address data is sourced from the US main postal service USPS. The database is updated daily and ZIP Code boundaries are updated as needed to accommodate changes to delivery areas.

Street names and house numbers are not changed frequently, however new builds are added to the database daily. If someone moves out of a house and it is not occupied, this will be updated as vacant on the USPS address database. You can read more about why you may not be able to find an address in our Missing Address guide.

In order to keep your address database up-to-date and maintained, implement our Address Lookup API on your address form to capture valid addresses.
