Frequently Asked Questions about the 540 Area Code
Who called me from a 540 number?
A 540 number is assigned to Roanoke, Virginia, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 540 code to look nearby, so a 540 number doesn't prove the caller is local. Recently, 1,913 unwanted-call complaints were reported to the FTC for numbers showing the 540 code (81% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 540 a scam area code?
No area code is a scam on its own. 540 is a normal, officially assigned code for Roanoke, Virginia. Spam callers spoof local codes to raise the odds you answer, so 540 on your caller ID says nothing about who is really calling. Recently, 1,913 unwanted-call complaints were reported to the FTC for numbers showing the 540 code (81% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 540 area code?
Repeated calls from different 540 numbers are usually spoofing: a robocaller rotates through 540 numbers so each call looks local and slips past simple blocks. Recently, 1,913 unwanted-call complaints were reported to the FTC for numbers showing the 540 code (81% 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 540 number?
If you aren't expecting a 540 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 540 area code?
Block a single 540 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 540 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 540?
Area code 540 covers Roanoke and the surrounding area in Virginia, spanning 164 cities with about 763,520 residents. It shares its area with overlay code 276.

Yes. 540 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Roanoke, Virginia. A real code can still show up on spoofed spam calls, so treat unknown 540 calls with normal caution.
What timezone is the 540 area code in?
The 540 area code is in the Eastern Time (ET). Because a number can be kept when someone moves or switches to VoIP, a specific 540 caller may not be in that zone.
How do I call a 540 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 540 and the seven-digit number. From a mobile phone you can usually just enter +1 540 followed by the number and let the phone add the exit code for you.
