County District Data
There are "County by Zip Code" and "County by Census Block, Block Group and/or Tract" county data files. Following are common problems that our competitors have:
100% accuracy for existing addresses, 98% accuracy for new addresses
Using its proprietary algorithms, USGeocoder combines census block data and U.S. Postal Addressing data to assign new addresses to census block, block group, tract, zip+4 and carrier route to the entire country and is possessions. USGeocoder can assign these addresses with a 98% accuracy.
Most frequently updated data you can find
USgeocoder is installed with 2010 Census TIGER data.
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 delivery to it.

USgeocoder also offers "Address Range-To-County" for better accuracy. Here is the sample header of "Address Range-To-County" data fils.
