UCaaS built for every U.S. state — HD calling, team meetings, messaging, and more, all on Oklahoma's 3 area codes. No hardware. No contracts. Live in minutes.
Oklahoma entered the NANP in 1947 with area code 405 for Oklahoma City and 918 for Tulsa and the rest of the state. This two-code structure has served Oklahoma remarkably well — both original territories have remained largely intact for over 75 years.
Overlay 539 was added to the 918 Tulsa territory in 2011 as the metro grew, and 572 was introduced as an overlay to 405 in 2022. Oklahoma remains one of the few states of its size where the original 1947 geographic boundaries are essentially unchanged.
Today Oklahoma is anchored by Oklahoma City, home to a population of around 4.0M, and its oil & gas sector keeps demand for local numbers high. Whether you are opening a Oklahoma City office or supporting customers statewide, a OK number keeps your business instantly recognisable across all 3 area codes — and with Ajoxi you can run every one of them, plus calling, video, and messaging, on a single platform.
Oklahoma is one of the rare states where both original 1947 area codes are still in use on essentially the same geographic territories — 405 for the west/center and 918 for the east — a stability almost unmatched among states of its population.
Oklahoma's 3 area codes cover the full state — from Oklahoma City to Norman and everywhere in between.
