Who calls from a 787 number

NANPA records the carrier each block of 787 numbers is assigned to. Of the 7.7 million 787 numbers assigned, 45% are with mobile carriers (Liberty Mobile Puerto Rico and T-Mobile); 41% with local phone companies (Puerto Rico Tel and Claro Puerto Rico); 13% with cable, internet-calling, business and other carriers (Optivon Telecommunications Services and Liberty Communications Of Puerto Rico).

An area code says where a number was issued, not where the caller is: people keep their numbers when they move, and caller ID can be set to show any number, which the FCC calls spoofing. If a call you did not expect asks for money or personal details, the FCC advises hanging up and calling the company back on a number you look up yourself. Unwanted calls can be reported to the FTC at ReportFraud.ftc.gov.
