Geographic Regions and Area Codes

Area Code 771 is a relatively new addition to the telecommunication landscape of Washington, D.C. It overlays the existing 202 area code, meaning both area codes coexist within the same geographic region. This overlay system was introduced to accommodate the growing demand for telephone numbers in the area. The major regions covered by Area Code 771 include:

  • Washington, D.C. (202, 771)
  • Maryland (240, 301)
  • Virginia (540, 571, 703)

This setup ensures that businesses and residents have ample number availability until 2054, making it a sustainable solution for the region's telecommunication needs.
