The 305-928 prefix belongs to area code 305 and is anchored to the Keys rate center (FL). In NANP terms, the prefix — or NXX — determines the rate center a number is billed against.

Code-holder of record: METROPCS, INC. (OCN 5562), assigned August 27, 2014. The prefix is pooled: its ten thousands-blocks can be shared among several carriers, so different 305-928 numbers may be served by different companies.

Caller ID showing 305-928 is not proof the call came from Keys: spoofing and porting both detach numbers from their origin. To verify a caller, hang up and dial the organization's published number, and report suspicious calls to the FTC.
