Unassigned area codes

Any area code listed as an unassigned area code is an invalid area code when it was last checked. If you're receiving a call from an unassigned area code, it is likely a telemarketer is spoofing the phone number, making it appear as if they are someone else to prevent the call from being blocked or ignored.
