Unfortunately there’s no easy, clear-cut way to figure out the origins of a blocked caller ID phone number. This is not to say that the task is impossible, just that it’s complicated. The means of obtaining this information can only be pursued if the call received from the blocked number is severely harassing in nature, because legal authorities are involved in tracking down the unknown caller. If the calls being received from a blocked number do not rise to the level of unlawful harassment, there are other safeguards you can put in place to make sure that only unblocked calls get through to your phone.
