Zip Code +4 Verification Software - QAS Online Glossary

Definition:
Zip code +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 QAS product suite adds the ZIP + 4 to every recognized address. This helps to ensure delivery, hence saving time and money.

Zip code +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.
