ZIP+4 Database Files & Sizes
The ZIP+4 database is a large dataset (over 1 GB compressed). Because of this large size, the data is broken down into 62 individual files (one for each state/territory). Each file contains the full data for the given state. Below are the State files available as well as their current Compressed and Uncompressed File Sizes. All files are delivered in compressed .ZIP format.
