Scammers

You can get a call from an unallocated number when it’s spoofed. Or, the owner of the number didn’t pay. Or, the telephone provider has network problems. Or, the number is no longer assigned.

No one who appears to be calling from 0000000000 or 1000000000 actually has those numbers assigned to them. Therefore, they are guilty of this spoofing tactic. Spoofing is when someone or something takes on another identity that does not belong to them—and in this way commits identity fraud.
