Frequently Asked Questions about the 787 Area Code
Who called me from a 787 number?
A 787 number is assigned to San Juan, Puerto Rico, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 787 code to look nearby, so a 787 number doesn't prove the caller is local. Recently, 41 unwanted-call complaints were reported to the FTC for numbers showing the 787 code (41% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 787 a scam area code?
No area code is a scam on its own. 787 is a normal, officially assigned code for San Juan, Puerto Rico. Spam callers spoof local codes to raise the odds you answer, so 787 on your caller ID says nothing about who is really calling. Recently, 41 unwanted-call complaints were reported to the FTC for numbers showing the 787 code (41% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 787 area code?
Repeated calls from different 787 numbers are usually spoofing: a robocaller rotates through 787 numbers so each call looks local and slips past simple blocks. Recently, 41 unwanted-call complaints were reported to the FTC for numbers showing the 787 code (41% 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 787 number?
If you aren't expecting a 787 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 787 area code?
Block a single 787 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 787 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 787?
Area code 787 covers San Juan and the surrounding area in Puerto Rico, spanning 253 cities with about 2,095,898 residents. No other code overlays this region, so 787 alone identifies the area.
Is 787 a real area code?
Yes. 787 is an active code in the North American Numbering Plan, assigned by NANPA and in service for San Juan, Puerto Rico. A real code can still show up on spoofed spam calls, so treat unknown 787 calls with normal caution.
What timezone is the 787 area code in?
The 787 area code is in the Atlantic Time (AST). Because a number can be kept when someone moves or switches to VoIP, a specific 787 caller may not be in that zone.
How do I call a 787 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 787 and the seven-digit number. From a mobile phone you can usually just enter +1 787 followed by the number and let the phone add the exit code for you.
