Every month, new addresses are created and the US Postal Service reassigns zip codes accordingly. USgeocoder responds to those changes with monthly updates for the closest to real time accuracy available in the marketplace. To maintain the highest level of accuracy, we work directly with the US Postal Office officials responsible for these assignments.
As redistricting occurs, we update our congressional district data within 30 days when the states publish the new-redrawn districts.
We include the District of Columbia and all US possessions.
