TIGER ZIP + 4 - QAS Online Glossary

Definition:
TIGER ZIP + 4, or a Topological Integrated Geographic Encoding and Reference/ZIP + 4® file, is a tool that combines United States Census Bureau TIGER files and USPS ZIP + 4 data to provide valuable location identification information such as latitude and longitude coordinates, down to the nearest intersection, for a given address.

The main benefit of TIGER ZIP + 4, is that it allows mailers to link their Zip +4 addresses to the US Census data. In most cases this data set gives exact lat/long coordinates down to the accuracy of the ZIP + 4™. Latitude and longitude lines are especially helpful in verifying addresses on both the front-end and the back-end.
