Is area code 539 a scam?
No. Area code 539 is a legitimate area code serving Tulsa since 2011. Scammers spoof caller ID to display 539 numbers, which is why complaints exist against a code that is itself genuine.
Neighbour spoofing is the reason a local-looking number is not a guarantee. A caller anywhere in the world can display a 539 number, and the number they display may belong to a real business in Tulsa that has nothing to do with the call.

Area codes that overlay 539
Area code 539 shares its geographic footprint with one other code: 918. Overlays are laid over an existing area rather than splitting it, so all local calls require the full ten-digit number.
Tulsa built its fortune on oil, and energy still shapes the city, though the mix has changed. The old "Oil Capital of the World" is now a hub for pipeline operators and midstream companies such as Williams and ONEOK, both headquartered downtown, alongside aerospace maintenance at American Airlines' Tulsa base, one of the largest aircraft maintenance facilities in the world. Banking (BOK Financial), manufacturing, and a growing remote-work population recruited by the Tulsa Remote program round out an economy that serves a metro of just over one million people (2020 census).
Who lives in the 539 region
Tulsa's city population was 413,066 at the 2020 census, with a median age of 35.6 and a median household income of $59,838 (DataUSA, 2024). The city is majority white with a large Black community concentrated in North Tulsa, home to the historic Greenwood district, and a Hispanic population of 19.8% (DataUSA, 2024). Spanish is the most common language after English, and businesses in East Tulsa in particular often operate bilingually. Vietnamese and Hmong communities are smaller but established.
What a 539 number signals to a caller
Area code 539 has overlaid 918 across northeastern Oklahoma since 2011. The 918 is part of Tulsa's identity, one of the city's nicknames outright, so 539 arrived with something to prove, but after more than a decade both codes read as local. Callers describe Tulsa business culture as friendly and unhurried on the phone, with relationships built before deals, and faith and community ties carrying real weight in who does business with whom. An outside caller should know that Tulsa is on Central Time and that a 539 number covers the same Green Country footprint as 918, from Bartlesville down to Muskogee.
