Frequently Asked Questions About Area Code 202
How does the 202/771 overlay system work?
New phone numbers may be assigned either the 202 or 771 area code, while existing 202 numbers remain unchanged. All calls within the 202/771 area now require 10-digit dialing (area code + 7-digit number). The 771 overlay became operational on November 9, 2021.
Do I need to change my 202 phone number to 771?
No. If you have an existing 202 phone number, you keep it. Only new phone numbers assigned after November 9, 2021 may receive the 771 area code. Your 202 number will not change.
Why was the 771 overlay necessary?
The D.C. Public Service Commission projected that the District would run out of new 202 phone numbers in 2022 due to population growth, increased government operations, and expanding telecommunications needs. The 771 overlay addresses this number shortage without requiring existing customers to change their numbers.
What is 10-digit dialing and when did it start?
10-digit dialing means you must dial the area code (202 or 771) plus the 7-digit phone number for all calls, including local calls within Washington D.C. This requirement began on October 24, 2021, as mandated by the FCC to support the 988 Suicide & Crisis Lifeline.
Can I still get a 202 phone number or only 771?
New phone numbers assigned after November 9, 2021 may receive either 202 or 771, depending on availability. Both area codes are functionally identical and cover the same geographic area.
What makes the 202 area code unique?
As the capital's original area code and the second area code ever assigned in the NANP system (1947), 202 serves critical government functions and international diplomatic communications. It's one of the most significant and recognizable area codes in the U.S., providing a direct line to the centers of power and influence in the nation's capital.
