Where is the 405 Area code?
The 405 area code serves as the primary code for central Oklahoma under the North American Numbering Plan (NANP). It covers the Oklahoma City metropolitan area and surrounding communities, including major cities such as Oklahoma City, Norman, Edmond, Stillwater, Moore, Shawnee, Midwest City, and Yukon.
This region features notable landmarks and hubs, including the Oklahoma State Capitol, Bricktown, Chesapeake Energy Arena, the University of Oklahoma, and the Myriad Botanical Gardens. Most businesses and residents in central Oklahoma rely on the 405 area code to maintain a local presence and facilitate communication across the region.
Time Zone
The 405 area code region follows the Central Time Zone (CT), which operates on UTC−6 / GMT−6 during standard time and shifts to UTC−5 / GMT−5 during daylight saving time. Daylight Saving Time begins on the second Sunday in March and ends on the first Sunday in November, when clocks are moved forward in the spring and set back in the fall. Businesses and residents using 405 area code phone numbers follow this schedule to stay aligned with local time standards across Oklahoma City and the surrounding central Oklahoma communities.
About the 572 Area Code in Oklahoma
The 572 area code was introduced in 2021 as an overlay for the 405 region to support the growing demand for phone numbers in central Oklahoma. It covers the Oklahoma City metro area and nearby key communities such as Norman, Edmond, and Stillwater, which contribute to industries such as government services and energy.
These sectors play a strong role in driving local economic activity and overall state growth, with Oklahoma County alone generating a Gross Domestic Product (GDP) of approximately $73.74 billion in 2024. This contributes significantly to the broader state economy, which reached over $274.42 billion by 2025.

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.
How Does a 405 Area Code Business Phone Number Work?
A 405 area code business phone number is a standard 10-digit number under the North American Numbering Plan (NANP) assigned to central Oklahoma. 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.
