Method 2: Dialing *69 to Trace the Unknown Number

Dialing *69 to Trace the Unknown Number

Dialing *69 on a landline isn’t new, but it is still essential today, and you can use it when you get a call with an unknown caller’s number or find out number(no) caller ID. Even if the person hangs up or you don’t want to pick up, you can dial *69 after the call is done, and it will connect you to the number that just called you.

While this move won’t give you the person’s exact number, it will reconnect you to them. You can then inquire why they called and try to gather insight into the person and his/her purpose.

Method 3: Dialing *57 to Track an Unknown Caller ID number

Those who routinely receive harassing phone calls or those from unknown numbers that continually hang up without talking might appreciate the *57 option.

When you dial *57, your phone will call back the number that just called you, similar to *69. The *57 feature lets the phone company track the last number that called you and record all relevant metadata. Authorities can use this archive of information if they need the records for legal cases.

However, you need to record the date and time that you select *57. However, if this information is lacking, it might delay your report.

Method 4: Contact Your Phone Company to Trace Unknown Number

A simple solution to obtaining the mystery phone number is to call your service plan provider for your phone. Most often, they can reveal the unknown number that called you with a few simple searches on their end. The representative acts as an anonymous caller ID service.

You can also get a full list of every number that has called you in a set period, whether their ID was blocked or not. Your company might also be able to assist you with additional measures you can take, such as blocking certain numbers so they cannot call you again.

It’s worth noting that the company may impose a charge for this service. While they may not, in some cases finding out the source of an anonymous caller can go beyond the scope of your plan.

Method 5: Report Scam Calls to the FTC

Once you discover that a call is coming from a telemarketer, you can report them to the Federal Trade Commission (FTC). You can perform this action online on the government website by entering the pertinent information.

The FTC highly monitors scam calls, and they rely on citizen reports to track current trends and offenders. By sharing your information, you are helping to end the act of undesired telemarketing and fraud that takes place.


Apple has input a feature into their phone’s operating system that allows you to filter out no caller ID numbers. The Silence Unknown feature essentially blocks unknown callers. Your phone won’t ring if it’s an unknown caller, but they can still leave a voicemail for you. It will still register as a missed call.

Most unknown calls are no more than a nuisance, but there are scammers out there trying to take advantage of you. So, it is important to remain vigilant regarding unknown calls because it could be an international call that will cost you hefty fees if you answer. Genuine callers will leave a message if it’s important.
