DO NOT return the call from someone calling from a 876 area code.
This is not a toll free "800" number, it is the international long distance code for the island nation of Jamaica. You are charged international and long distance rates for calling this number. Other international/long distance area codes are 809, 284, and 649.

Scammers use these numbers to not only try to scam you out of money, but also sting you with high phone call rates.
