Got a call from 645? Here's what it means.
The three digits after the +1 country code identify the numbering plan area a number was issued in. For 645, that area is Florida (Miami-Dade County and the Florida Keys). If you don't know anyone there, the call is more likely to be a business, a call centre or an automated dialer than a personal contact.
An area code alone can't tell you who is calling. Numbers are portable, and VoIP providers can issue a 645 number to a caller located anywhere in the world — a technique known as neighbour spoofing, where a familiar area code is used to make a call look local.
To identify the caller, run the full 10-digit number through a lookup. WhoCallsMe checks the number against carrier records, business directories and community spam reports, and shows the line type, carrier and reported risk.
