The search for the “202 area code” is a highly specific and high-intent geographical query, as this code is globally recognized as the identifier for the capital of the United States.
The 202 area code is the original, exclusive telephone code for Washington, D.C., the capital of the United States. Established in 1947, 202 has long been the sole area code for the District of Columbia. Due to the depletion of available phone numbers, the 202 area code is now served by an overlay area code, 771, which means 10-digit dialing is mandatory for all calls within the nation’s capital.
This article details the location, prestige, and dialing rules for the 202/771 area code complex.

The 771 Area Code Overlay and 10-Digit Dialing
For decades, 202 was one of the few area codes covering a major metropolitan area that had never been split or overlaid. That changed due to the proliferation of mobile phones, fax machines, and increased demand.
The 771 Overlay
- New Code: Area code 771 was implemented as an overlay for the 202 region, with new phone lines and services being assigned the 771 prefix starting in late 2021.
- Coverage: The 771 area code covers the exact same geographic area as the 202 area code.
Mandatory 10-Digit Dialing
Because the 202 and 771 codes share the same territory, 10-digit dialing is now required for all calls within Washington, D.C. (This change became mandatory on October 9, 2021).
- Rule: You must dial the full Area Code + 7-Digit Local Number for every local call.
- Example: Calling a number in Georgetown from a number in Capitol Hill requires dialing 202-XXX-XXXX (or 771-XXX-XXXX).
Actionable Steps Required
- Update Contacts: Residents and businesses must update all mobile phone contact lists, automated equipment (PBXs, modems, medical alert systems), and business stationery to include the full 10-digit number.
- Local Calling Remains Local: The transition to 10-digit dialing did not change the cost of the call; what was a local call remains a local call, regardless of whether you dial 202 or 771.
Frequently Asked Questions (FAQ)
What is the most common nearby area code to 202?
The 202 area code is surrounded by several close-proximity area codes in the neighboring states:
- Maryland: 301 (and its overlay, 240).
- Virginia: 703 (and its overlay, 571).
Many calls between 202 and these codes are considered local calls under the Washington Metropolitan Exchange Area (WMEA).
Does having a 202 number still carry prestige?
Yes. The original 202 area code carries significant historical and cultural prestige, particularly within the business, political, and academic communities. While 771 numbers are fully functional and local, the 202 prefix remains highly desirable.
Are 202 numbers used by scammers?
Yes. Scammers frequently use caller ID spoofing to disguise their calls with the 202 area code, attempting to gain trust by impersonating government agencies (like the IRS, FBI, or Social Security Administration). The IRS and other agencies will not initiate contact demanding immediate payment by phone. Always be wary of unsolicited calls from a 202 number asking for personal information.
