01 — District of Columbia at a glance

District of Columbia, by the numbers.

712KPopulation
1市外局番
1federal
1947First code issued
EasternTime zone

Washington D.C. was assigned area code 202 in 1947 — the low digit sum made it fast to dial on rotary phones, reflecting the capital's priority in AT&T's original numbering scheme.

While the surrounding Virginia and Maryland suburbs have spun off dozens of codes over the decades, 202 has remained uniquely tied to the ten-square-mile District itself, unchanged since the system began.

Today District of Columbia is anchored by Washington, D.C., home to a population of around 712K, and its federal government sector keeps demand for local numbers high. Whether you are opening a Washington office or supporting customers statewide, a DC number keeps your business instantly recognisable across all 1 area code — and with Ajoxi you can run every one of them, plus calling, video, and messaging, on a single platform.

Did you know?

Area code 202 was deliberately chosen for the nation's capital in 1947 — the low digits (2-0-2) dialed faster on rotary phones than high-digit codes, giving the White House and federal agencies a practical speed advantage.

02 — Coverage map

Every District of Columbia code, on the map.

District of Columbia's 1 area code covers the full state — from Washington to Capitol Hill and everywhere in between.

202The iconic code

Washington's most recognised prefix.

Assigned to the U.S. capital in 1947, 202 is one of the most recognized area codes on earth — every call to Congress, the White House, and federal agencies originates here.
