The state uses several area codes, including 405, 572, 918, 539, and 580, to cover different regions. Among them, the 405 area code primarily serves central Oklahoma, including Oklahoma City, Norman, Edmond, Stillwater, Moore, Shawnee, Midwest City, and Yukon.
Central Oklahoma, covered by the 405/572 area code, is a key economic hub with industries such as energy, aerospace, agriculture, healthcare, education, and manufacturing. Major employers in this region include the University of Oklahoma, Tinker Air Force Base, and INTEGRIS Health, which play a significant role in the local economy. Additionally, for the business, having a local 405 or 572 area code phone number allows them to strengthen their presence in central Oklahoma, easily connect with customers and partners, and maintain reliable communication across the region.
History of Area Code 405
When the Federal Communications Commission (FCC) decided to make phone numbers public in the USA in 1947, area code 405 was introduced to serve the demand of the entire Oklahoma state. It was one of the original 85 area codes, initially implemented to serve telephone demand nationwide.
After over half a century of service, the 405 was split in 1997 by adding the new area code 580. However, within two decades, phone number usage exceeded that, leading to adding the new area code 572 as an overlay to 405.
Overall, Oklahoma has 5 area codes. Because 405 has an overlay with area code 572, all callers in the region must use the full 10-digit format area code + phone number (e.g., 405-555-xxxx) for every local call. The “1” prefix is only required for long-distance calls from some landlines. International callers dial +1 + 405 + phone number, depending on their country’s exit code and dialling rules.

A 405 area code is an overlay to the 572 area code and works as a local phone number by routing calls through the region’s landline, mobile, and VoIP systems. This makes it easy for customers anywhere in the 405/572 region to reach your business using a familiar local number.
