Oklahoma's 539 area code is an overlay sharing geography with the long-running 918 across the Tulsa region and northeastern Oklahoma. Tulsa anchors the directory's records here. The city sits along the Arkansas River in northeastern Oklahoma, organized around a downtown that retains a substantial cluster of art deco buildings dating from the city's oil-boom era of the 1920s, alongside a substantial concentration of energy-industry headquarters and a growing healthcare and aerospace base. The 539 designation, part of the North American Numbering Plan, has been filling with allocations as the broader 918 region's number demand has continued to grow.
In records the directory has compiled for 539 numbers, other Oklahoma cities — Lawton and Oklahoma City — appear regularly. Neither is inside the 539 footprint. The pattern reflects standard public-record dynamics across Oklahoma. The directory currently documents 29 distinct prefixes within 539 in detail, a working subset of the prefix population the code carries.
Tulsa's home values come in below the US median, with median household income running below the national figure. The city's median age sits a few years under the US reading, and population places Tulsa as the second-largest city in Oklahoma. The 539 footprint shares those demographics with 918 because both codes serve the Tulsa region and northeastern Oklahoma in overlapping form, and the broader region's economic and demographic profile reflects the city's long-running role as an energy-industry center and a regional commercial hub for the surrounding counties.
