City population is shown in full. The share of each city inside 457 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 457 cover?
1,137,593 residents across 31 counties, counted inside the 457 boundary — a county split between codes contributes only its part.

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 457 Area Code
Who called me from a 457 number?
A 457 number is assigned to Shreveport, Louisiana, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 457 code to look nearby, so a 457 number doesn't prove the caller is local. Recently, 3 unwanted-call complaints were reported to the FTC for numbers showing the 457 code (33% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 457 a scam area code?
No area code is a scam on its own. 457 is a normal, officially assigned code for Shreveport, Louisiana. Spam callers spoof local codes to raise the odds you answer, so 457 on your caller ID says nothing about who is really calling. Recently, 3 unwanted-call complaints were reported to the FTC for numbers showing the 457 code (33% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 457 area code?
Repeated calls from different 457 numbers are usually spoofing: a robocaller rotates through 457 numbers so each call looks local and slips past simple blocks. Recently, 3 unwanted-call complaints were reported to the FTC for numbers showing the 457 code (33% 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 457 number?
If you aren't expecting a 457 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 457 area code?
Block a single 457 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 457 code also stops legitimate local calls, so use it only as a last resort.
