About District Of Columbia ZIP codes

The District of Columbia is served by 252 ZIP codes spanning the range of 20001 to 20599, using the prefixes 200, 202, 203, 204, and 205. Despite covering just 68 square miles, D.C. has an unusually high concentration of ZIP codes because many are dedicated to individual federal agencies, government buildings, and organizations rather than traditional residential delivery routes. As the seat of the U.S. federal government, Washington, D.C. is home to iconic ZIP codes like 20500 for the White House and 20510 for the U.S. Senate. Whether you're looking up a neighborhood ZIP code or tracking down a government office address, understanding D.C.'s unique postal geography is essential for accurate mail delivery in the nation's capital.

District Of Columbia ZIP codes use the prefixes 200, 202, 203, 204, and 205, all beginning with the digit 2, which is assigned to the mid-Atlantic region of the United States. The 200 prefix is uniquely reserved for Washington, D.C., making it one of the most recognizable ZIP code prefixes in the country. The additional prefixes (202–205) accommodate the large volume of government agencies, organizations, and specialized mail processing within the district.

The District of Columbia itself accounts for all 252 ZIP codes because, as a federal district rather than a state, it functions as a single county-equivalent jurisdiction encompassing the entire territory.
