NOTE: L801 data is available free on the post office web site. I am not selling the data, I am performing the service of putting the data in an SQL file for you.

L801 data lists zip codes into groups for bulk mailing purposes. If you are making a system for organizing addresses for bulk mail, you need to group your addresses by AADC region (Automated Area Distribution Center), where the 3 digit codes are the first three digits of the address zip codes.

The data comes in the form of two tables. The first tables list each AADC zone by name, with a corresponding unique id number. The second table lists each 3 digit zip code individually, with an id number that corresponds to the AADC zone that zip belongs to. The data is based on the August 2nd, 2007 update of the AADC data.

This table contains Longitude and latitude data for 43,187 zip codes. This is nearly all (possibly all) of the zip codes in the USA. Specifically, each row contains a zip code, that zip code's longitude and latitude. Then it contains three trigonometric fields that help shorten up the math required to calculate distances between zip codes. That is the sine and cosine of the latitude, and the radion of the longitude. If these extra fields are not needed, you can simply delete the columns.
