City population is shown in full. The share of each city inside 337 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.
What counties does area code 337 cover?

Caller ID is easily spoofed, so these figures reflect the number shown on caller ID, not the caller's true location – an area code alone never identifies a caller. The FTC does not verify the facts in these complaints. Source: FTC Do Not Call (DNC) Reported Calls Data, retrieved 2026-08-17.

Frequently Asked Questions about the 337 Area Code
Who called me from a 337 number?
A 337 number is assigned to Lafayette, Louisiana, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 337 code to look nearby, so a 337 number doesn't prove the caller is local. Recently, 758 unwanted-call complaints were reported to the FTC for numbers showing the 337 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 337 a scam area code?
No area code is a scam on its own. 337 is a normal, officially assigned code for Lafayette, Louisiana. Spam callers spoof local codes to raise the odds you answer, so 337 on your caller ID says nothing about who is really calling. Recently, 758 unwanted-call complaints were reported to the FTC for numbers showing the 337 code (61% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 337 area code?
Repeated calls from different 337 numbers are usually spoofing: a robocaller rotates through 337 numbers so each call looks local and slips past simple blocks. Recently, 758 unwanted-call complaints were reported to the FTC for numbers showing the 337 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 337 number?
If you aren't expecting a 337 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 337 area code?
Block a single 337 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 337 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 337?

Is 337 a real area code?
Yes. 337 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Lafayette, Louisiana. A real code can still show up on spoofed spam calls, so treat unknown 337 calls with normal caution.
What timezone is the 337 area code in?
