UCaaS built for every U.S. state — HD calling, team meetings, messaging, and more, all on Maryland's 5 area codes. No hardware. No contracts. Live in minutes.
Maryland began with area code 301 covering the entire state in 1947. The booming Washington D.C. suburbs drove a split in 1991 when 410 was created for Baltimore and the eastern half of the state.
Overlay 443 was added to the 410 territory in 1997 as Baltimore's business demand grew, and 240 became an overlay for 301 in 2012 — giving Maryland four active codes driven largely by the dense D.C. suburb corridor.
Today Maryland is anchored by Annapolis, home to a population of around 6.2M, and its federal government & defense sector keeps demand for local numbers high. Whether you are opening a Rockville office or supporting customers statewide, a MD number keeps your business instantly recognisable across all 5 area codes — and with Ajoxi you can run every one of them, plus calling, video, and messaging, on a single platform.
Maryland was among the first states to adopt area code overlays rather than geographic splits in the 1990s, a strategy driven by the extraordinary density of government, defense, and tech demand in its Washington D.C. suburbs.
