This file contains districts and representatives for the current 118th Congress by ZIP Code. There are two versions of this product: Standard and Extended. See comparison chart and watch video below for a brief explanation.
It’s common to have multiple congressional districts within a ZIP Code area. A district may cover a tiny portion, or all of it. For this reason, we include an estimate of the ZIP Code coverage area for each district. We use multiple sources, including our own plotting, to maintain a complete and accurate Congressional District to ZIP Code relationship.| Standard Version | Extended Version | |
