Frequently Asked Questions about the 918 Area Code
Who called me from a 918 number?
A 918 number is assigned to Tulsa, Oklahoma, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 918 code to look nearby, so a 918 number doesn't prove the caller is local. Recently, 732 unwanted-call complaints were reported to the FTC for numbers showing the 918 code (78% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 918 a scam area code?
No area code is a scam on its own. 918 is a normal, officially assigned code for Tulsa, Oklahoma. Spam callers spoof local codes to raise the odds you answer, so 918 on your caller ID says nothing about who is really calling. Recently, 732 unwanted-call complaints were reported to the FTC for numbers showing the 918 code (78% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 918 area code?
Repeated calls from different 918 numbers are usually spoofing: a robocaller rotates through 918 numbers so each call looks local and slips past simple blocks. Recently, 732 unwanted-call complaints were reported to the FTC for numbers showing the 918 code (78% flagged as robocalls). Blocking one number rarely helps; voicemail screening, your carrier spam filter, and the Do Not Call Registry work better.
Should I answer an unknown 918 number?
If you aren't expecting a 918 call, let it ring to voicemail. Legitimate callers leave a message, most robocallers hang up when no one picks up, and answering can mark your number as active and bring more calls.
How do I block calls from the 918 area code?
Block a single 918 number from your recent-calls list (iPhone: tap the number, then Block this Caller; Android: tap the number, then Block or report spam). To cut the volume, turn on Silence Unknown Callers on iPhone or spam protection on Android, enable spam filtering from your carrier, and register at DoNotCall.gov. Blocking the entire 918 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 918?
Area code 918 covers Tulsa and the surrounding area in Oklahoma, spanning 324 cities with about 1,169,952 residents. No other code overlays this region, so 918 alone identifies the area.
Is 918 a real area code?
Yes. 918 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Tulsa, Oklahoma. A real code can still show up on spoofed spam calls, so treat unknown 918 calls with normal caution.
What timezone is the 918 area code in?
The 918 area code is in the Central Time (CT). Because a number can be kept when someone moves or switches to VoIP, a specific 918 caller may not be in that zone.
How do I call a 918 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 918 and the seven-digit number. From a mobile phone you can usually just enter +1 918 followed by the number and let the phone add the exit code for you.
