Frequently Asked Questions about the 771 Area Code
Who called me from a 771 number?
A 771 number is assigned to Washington, District of Columbia, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 771 code to look nearby, so a 771 number doesn't prove the caller is local. Recently, 1,229 unwanted-call complaints were reported to the FTC for numbers showing the 771 code (64% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 771 a scam area code?
No area code is a scam on its own. 771 is a normal, officially assigned code for Washington, District of Columbia. Spam callers spoof local codes to raise the odds you answer, so 771 on your caller ID says nothing about who is really calling. Recently, 1,229 unwanted-call complaints were reported to the FTC for numbers showing the 771 code (64% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 771 area code?
Repeated calls from different 771 numbers are usually spoofing: a robocaller rotates through 771 numbers so each call looks local and slips past simple blocks. Recently, 1,229 unwanted-call complaints were reported to the FTC for numbers showing the 771 code (64% 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 771 number?
If you aren't expecting a 771 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 771 area code?
Block a single 771 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 771 code also stops legitimate local calls, so use it only as a last resort.

Is 771 a real area code?
Yes. 771 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Washington, District of Columbia. A real code can still show up on spoofed spam calls, so treat unknown 771 calls with normal caution.
What timezone is the 771 area code in?

How do I call a 771 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 771 and the seven-digit number. From a mobile phone you can usually just enter +1 771 followed by the number and let the phone add the exit code for you.
