Is Area Code 787 a Scam? Puerto Rico Spam & Safety Guide

Received a missed call or text from a 787 number? Although 787 uses the same 1-plus-three-digit format as a U.S. area code, it is actually the international dialing code for the Commonwealth of Puerto Rico (a U.S. territory in the Caribbean). This is one of the most abused codes in the North American Numbering Plan, and calling it back can cost you money. Here is what 787 really is, the scams tied to it, and how to protect yourself.

✅ Quick Safety Verdict

Is 787 an official code? Yes, but it is international—787 belongs to the Commonwealth of Puerto Rico (a U.S. territory in the Caribbean), not the United States. Is it safe to answer? Treat unexpected 787 calls with high caution. Never call back an unknown 787 number: it is strongly linked to the prize, utility, and impostor scam, and return calls can trigger premium international charges.

Common Scams Reported From Area Code 787

Because 787 can be mistaken for a domestic number, it is a favorite of overseas fraud rings. The most reported schemes tied to 787 are:

One-Ring (Wangiri) Call-Back Scam

Your phone rings once from a 787 number and hangs up, hoping curiosity makes you call back. The return call connects to a premium international line that racks up per-minute charges split with the scammer. Do not return calls to unknown 787 numbers.

Prize, Lottery & Impostor Scams

Callers claim you have won a sweepstakes, lottery, or vacation and must pay “taxes” or “fees” via gift cards or wire transfer to collect. No legitimate lottery asks winners to pay up front, and U.S. agencies do not call from 787.

Text Message (SMS) / Smishing Alerts

Texts from 787 may claim a delivery problem, a bank alert, or a prize and include a link. Do not tap links or reply—replying confirms your number is active and invites more attempts.

How to Identify & Verify Unknown Callers From 787

Let it ring. Legitimate callers leave a voicemail; most scam auto-dialers do not.
Search the number. Paste the full 10-digit number into a search engine or a reverse-lookup site to see if others reported it as spam.
Know the code. 787 is an international code for Puerto Rico, so it will never be your neighbor’s local line—see our area code 787 reference.
Call back on an official number. If a caller claims to be your bank or a government agency, hang up and dial the number printed on your card or the agency’s official website—never the number that called you.
Never share codes. No legitimate caller needs a one-time passcode, PIN, or password read aloud.
