Prefix 305-290 — Keys, FL
The 305-290 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.
Keys is part of the Miami-Fort Lauderdale-Pompano-West Palm Beach, FL Metropolitan Statistical Area. For routing purposes it sits in LATA 460. Numbers here keep Eastern time.
The assigned code holder is METROPCS, INC., operating company number 5562, assigned May 10, 2011. This is a pooled prefix — expect numbers within it to be split across more than one carrier in 1,000-number blocks.
Caller ID showing 305-290 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.
