MAP: Washington D.C. Area Codes

This is an area code map of Washington D.C. as of 2001, showing the current borders of area codes within this given state. In many cases, a single area code has been split into two or more other area codes, meaning that BBS numbers from the 1980's might not be accurately reflected from this map. A simple rule of thumb is that any area code with a 1 or 0 for the middle digit was probably the area code for all the state around it that is now populated by area codes with 2-9 in the middle digit.

All area code maps on this site were acquired from the North American Numbering Plan information site. The maps themselves were generated for NANPA.COM by Geographic Data Technology.
