Congressional District Data
Your source of existing and new congressioal district data Most accurate, complete, and up-to-date congressional district andAs the entire country is going through redistricting during the 2012 election year, it's critical that you have accurate district assignments for election campaigns. Upon states releasing their new boundary files, USgeocoder takes the new boundary data and integrates it with our precise GIS data and the latest postal data to produce the new congressional and state legislative district data.
With 100% accuracy and the most frequent update schedule, USgeocoder brings you the best congressional district and representatives data you can trust for both existing and redistricted districts!
There are "Congressional District by 5 Digit Zip Code" and "Congressional District by 9 Digit Zip Code" data files. Following are the common problems that our competitors have:
100% accuracy for existing district data, 99% accuracy for new district data
USgeocoder merges nationwide data from US Census TIGER/Line with Postal Service mailing address files and other sources to produce the most accurate and comprehensive matching of zip code and address range to Congressional district files available anywhere. We provide as close to 100% accuracy rate for district assignments to current and new congressional districts you can get nationwide.
When new streets are constructed, USgeocoder uses proprietary algorithms to assign them to their proper political districts before they appear on government maps. Our more precise geocoding allows for nationwide accuracy rates above 99% for the new congressional districts in the 2012 elections.
Most frequently updated data you can find
USgeocoder uses the 2010 Census TIGER data upon which all political districts are built.
Every month, USgeocoder uses US Postal Service data to update the TIGER/Line census files. Typically, a new address is available to USGeocoder within thirty days after the Postal Services' first delivers to it.
For congressional representatives data, Representative's phone and email contact information for main and district offices, committee assignments and staff contact information are updated on a monthly basis.
Our files are updated within days of each new state or US redistricting publication that has passed the challenge period without challenges or has resolved the challenge. We also may load a state when our judgment indicates the challenges are either irrelevant to this election cycle, or unlikely to prevail. Court ordered changes are integrated into our data within our regular update cycles.
Covering the entire country and its possions
USgeocoder provides the most complete congressional district data. We cover the 50 states, District of Columbia, Puerto Rico and the rest of the island territories.

The "Address Range to District File" includes all the information in the Zip 9 to district file, plus address to district matching for addresses for which there is no complete zip+4 or USPS delivery.

Using federal standards for naming convention
We use THE GOVERNMENT STANDARD for our district names.
The district names in our files are provided by the states and automatically adopted by the federal government. The naming convention and field lengths are set by census Bureau to accommodate the requirements of each state. The federal governments use them for all federal matters and communications.
