History of the 405 Area Code
- 1947: 405 is created as an original area code. It covers the entire state of Oklahoma.
- January 1, 1953: northeastern Oklahoma, including Tulsa, becomes 918.
- November 1, 1997: southern and western Oklahoma become 580. 405 is left with the central part of the state.
- January 2020: regulators announce that 572 will overlay 405.
- January 2021: ten-digit dialing becomes mandatory in central Oklahoma as the overlay takes effect.
The Code in the Middle
After the 1997 split, 405 became the only Oklahoma area code that does not touch another state. It sits entirely in the middle, surrounded by 580 and 918. People with existing 405 numbers kept them when 572 arrived. New customers are now mostly given 572, which covers the same cities.
How to Dial a 405 Number
You need the area code for every call, even a local one.
- From the US or Canada: 1 + 405 + the seven-digit number
- From another country: your exit code + 1 + 405 + the seven-digit number
Is a Call From 405 a Scam?
A 405 number usually belongs to someone in the Oklahoma City area. State agencies, two large universities, energy companies and an air force base all call from it, and scammers copy those callers.
Watch for these warning signs:
- Threats of arrest, a lawsuit or a service shut-off unless you pay today
- Offers of a prize, a loan or a job that need a fee first
- Callers who already know part of your details and ask you to “confirm” the rest
- One-ring calls that try to make you call back
Caller ID can be spoofed, so the number on your screen does not prove where a call comes from.
What to do with an unknown 405 call
- Do not answer numbers you do not know.
- Never share a PIN, password or passcode with someone who called you.
- Block repeat callers and turn on your carrier spam filter.
- Report scam calls at reportfraud.ftc.gov and register at donotcall.gov.
- Forward spam texts to 7726 (SPAM).
