ZIP +4 verification software

Definition:

ZIP + 4® verification software verifies US addresses down to their USPS® 9 digit ZIP code™.

When performing address verification with a ZIP + 4®, the user can pinpoint an address down to be a few block radius. Although many people do not know their ZIP + 4®, the Experian Data Quality product suite adds the ZIP + 4® to every recognized address. This helps to ensure delivery, hence saving time and money.

Zip + 4® verification software works both on the front-end and the back-end. On the front-end, the ZIP + 4® will be added upon entering the address. Meanwhile, with back-end address correction software, the ZIP + 4® will either be added or corrected for all existing addresses.
