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. 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. 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. 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.
Where is area code 457?
Area code 457 covers Shreveport and the surrounding area in Louisiana, spanning 197 cities with about 642,311 residents. It shares its area with overlay codes 318, 504.
Is 457 a real area code?
Yes. 457 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Shreveport, Louisiana. A real code can still show up on spoofed spam calls, so treat unknown 457 calls with normal caution.
What timezone is the 457 area code in?
The 457 area code is in the Central Time (CT). Because a number can be kept when someone moves or switches to VoIP, a specific 457 caller may not be in that zone.
How do I call a 457 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 457 and the seven-digit number. From a mobile phone you can usually just enter +1 457 followed by the number and let the phone add the exit code for you.
