While you may often find that it’s a telemarketer, other times, the caller may hang up as you answer. Deciphering who the caller was becomes even more important in that situation. Other situations where you may want to find an unknown caller may be to monitor your kid’s phone or find out if your partner is cheating.

In this article, I will explain how to find out the owner of an unknown phone number for these specific circumstances.

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 didn’t give me the person’s exact number, it helped me reconnect with 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 get calls often from numbers that 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. I found out that 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, making it easier to check unknown number details through official channels.

However, I suggest recording the date and time when you use the *57 method. If this information is lacking, it might delay your report.

Method 4: Contact Your Phone Company to Trace Unknown Number

A simple solution that I discovered for finding the unknown caller’s information is to obtain the mystery phone number by calling your service plan provider from your phone. Most often, they will reveal the unknown number that called you with a few simple searches on their end, helping you find unknown number details without Truecaller. The representative acts as an anonymous caller ID service in this process.

I could also get a full list of every number that has called me in a set period, no matter if their ID was blocked. Your company might also be able to assist you, and you can take additional measures, 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 it 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.

How do you silence unknown callers from your iPhone?

Apple has an inbuilt feature in their phone’s operating system that allows you to filter out numbers with no caller ID. 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. However, I have noticed that it still registers the number as a missed call.

Are unknown calls dangerous?

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.

Summary

  • For a blocked caller ID number, try *69
  • To report the call, dial *57
  • Spokeo and Intelius can help you track down the person behind a number and find unknown number details online free without complex setups.
  • The app Truecaller will help you screen your calls through caller ID and check unknown number details online efficiently.
  • Report all telemarketers to the FTC to avoid unwanted calls
