All zip to district tables are range files

We are now offering a very affordable table that matches zip codes to congressional districts for only $450.00 per year. This table is assembled using information from the U.S. Postal Service and is quite accurate, with a margin of error of two to three percent (out of eight gigs of data).  The table, which reflects redistricting in Maine and Texas, is available in text, Access 2000, and dBase IV formats.  The database is updated quarterly and updates are included in the price.  Also included in the price are separate text tables with all the DC contact information for Representatives and Senators, which is updated weekly.  This table is our most popular product.  Call 703-799-1189 to order or send us an email.   Download a sample.

Please see our zip to district Q & A for more information about this table.
