Dial *57 (from a touch-tone phone) or 1157 (from a rotary-dial phone) immediately following the blocked call number you want to trace.
The number will be recorded by the telephone company’s unlawful call center.
Can * 67 be traced by police?
“As soon as the call is placed, it can be tracked and traced to where it is being originated.” Dialing *67 may cloak your call from other Caller ID-equipped phones, but not from your carrier or the authorities.
Can police trace a blocked number?
Any anonymous calls or calls from private numbers will be blocked on your cell phone. You should file a complaint regarding these blocked calls and ask them to look into the matter. The police will trace a blocked call and issue warnings to the offending party.
Can you trace a no caller ID number?
No Caller ID calls are the worst, there is no denying it. With TrapCall, you can unmask these blocked numbers and find out exactly who’s calling you from No Caller ID. That means their phone number, name, and even their address.
Can you trace an unknown number?
You still have another option to try even if using *57 call trace or calling your phone company does not reveal the identity of the caller. TrapCall is a paid service that unmasks blocked and unknown callers by having you decline the call and then the same caller rings back with the number visible to you.
