City population is shown in full. The share of each city inside 737 is measured from Census tract centroids, not estimated from a rate-center match – so a city split between two codes appears on both, at the fraction each one actually holds. The “% of listed-city population” column uses the full populations of the cities listed here.

Frequently Asked Questions about the 737 Area Code
Who called me from a 737 number?
A 737 number is assigned to Austin, Texas, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 737 code to look nearby, so a 737 number doesn't prove the caller is local. Recently, 623 unwanted-call complaints were reported to the FTC for numbers showing the 737 code (61% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 737 a scam area code?
No area code is a scam on its own. 737 is a normal, officially assigned code for Austin, Texas. Spam callers spoof local codes to raise the odds you answer, so 737 on your caller ID says nothing about who is really calling. Recently, 623 unwanted-call complaints were reported to the FTC for numbers showing the 737 code (61% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 737 area code?
Repeated calls from different 737 numbers are usually spoofing: a robocaller rotates through 737 numbers so each call looks local and slips past simple blocks. Recently, 623 unwanted-call complaints were reported to the FTC for numbers showing the 737 code (61% 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 737 number?
If you aren't expecting a 737 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 737 area code?
Block a single 737 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 737 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 737?
Area code 737 covers Austin and the surrounding area in Texas, spanning 73 cities with about 2,322,934 residents. It shares its area with overlay code 512.
When did area code 737 go into service?
Area code 737 went into service on July 1, 2013. It was added as an overlay of 512, so 737 numbers serve the same area that 512 already covered.
Is 737 a real area code?
Yes. 737 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Austin, Texas. A real code can still show up on spoofed spam calls, so treat unknown 737 calls with normal caution.
What timezone is the 737 area code in?
The 737 area code is in the Central Time (CT). Because a number can be kept when someone moves or switches to VoIP, a specific 737 caller may not be in that zone.
How do I call a 737 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 737 and the seven-digit number. From a mobile phone you can usually just enter +1 737 followed by the number and let the phone add the exit code for you.
