+1 268, 284, 473, 649, 664 and 767: Caribbean One-Ring Codes

+1 268, 284, 473, 649, 664 and 767 are area codes for Caribbean countries (Antigua and Barbuda, the British Virgin Islands, Grenada, Turks and Caicos, Montserrat and Dominica). They share the +1 country code, so they look like US numbers, but calling them back is an international call. The FTC lists all six in its warning about 'one-ring' scams.

What these numbers look like

From abroad: +1 NPA XXX XXXX
Inside Caribbean: 1 NPA XXX XXXX from the US/Canada

NPA is the three-digit area code. These islands are separate countries or territories within the North American Numbering Plan, so there is no extra international prefix to warn you.

Who uses Caribbean one-ring codes numbers?

Each of these codes was split from the old Caribbean code 809 in the 1990s. NANPA's database lists: 268 Antigua and Barbuda (in service 1 April 1996), 664 Montserrat (1 July 1996), 649 Turks and Caicos Islands (1 June 1997), 284 British Virgin Islands (1 October 1997), 767 Dominica (1 October 1997) and 473 Grenada (31 October 1997). Each country or territory manages its own numbers through its national regulator; NANPA administers the area codes. The FTC's one-ring list also includes 809, 829 and 849 (Dominican Republic) and 876 (Jamaica), which have their own pages.

268	Antigua and Barbuda
284	British Virgin Islands

664	Montserrat
767	Dominica

Who is calling you from a Caribbean one-ring codes number?

If you have friends, family or a booking in one of these islands, the call may be real. A single ring and a missed call from one of these codes, with no connection to the Caribbean, is the pattern the FTC describes: an autodialer rings your phone once hoping you'll call back. The callback can reach a line that charges you an international rate and keeps you on the phone.

Scams seen with Caribbean one-ring codes numbers

One-ring scam: according to the FTC, scammers use autodialers to ring cell phones once, then hope you call back. If you do, you may be charged a per-minute fee on top of international rates. The FTC's alert lists 268, 284, 473, 664, 649, 767, 809, 829, 849 and 876.
The FCC says charges from these callbacks can appear on your bill as premium services, international calling or toll calling, and that scammers may also spoof caller ID.
Voicemail variant (FCC): a message asks you to call an unfamiliar area code to 'schedule a delivery' or about a 'sick' relative.

What to do about a call from Caribbean one-ring codes

Don't pick up or call back an unknown number from these codes. The FTC says the cost comes from calling back, not from receiving the call.
Before returning any unfamiliar call, check whether the area code is international.
If you don't call abroad, ask your carrier to block outgoing international calls (FCC).
If you were billed, first dispute it with your carrier. If that fails, complain to the FCC at consumercomplaints.fcc.gov and to the FTC at ReportFraud.ftc.gov.
