It allows you to easily trace calls made to your phone number. Essentially, *57 records the calling number and other identifying information such as the date and time of the call. This information can then be used to request a complaint with your phone provider or to report the call to law enforcement.
Pick up the phone and press *57 (touch tone) or 1157 (rotary). You'll hear a confirmation tone and message will be heard If the trace is successful. You must keep a written log of the date and time of harassing calls to retrieve Call Trace information. You'll hear an error message if the call can't be traced.
Some carriers also allow you to dial *57 for a Call Trace option, but if the trace is successful you will not get the traced number directly, and will have to contact local law enforcement to get the information and prove that you have a legitimate reason for tracing the number.
To activate it, simply press *57. There is no charge for the connection, but charges and fees for using Call Trace may vary. The records of all traced calls will be released to a law enforcement agency only.
In conclusion, *57 is an easy-to-use service that enables you to track unwanted phone calls. However, it's important to note that *57 only works if you use it immediately after a call.
To activate the feature from most UT phones: Hang up the receiver, pick receiver back up and press *57 (star-five-seven) immediately following a threatening or harassing phone call, and before making another call.
Use the *69 code to trace unknown numbers
This feature provides details of the previous caller's number and, if they're listed in a public database, their name and address. Depending on your phone service provider, *69 may include a dial-back option allowing you to return the call and find out who called you.
All that you have to do is enter *67 before you dial the number. Keep in mind that you'll have to enter their number the long way. You can't just find their contact in your phone and select the “Call” option. It'll look something more like this instead: *67-XXX-XXX-XXXX.
Call Trace (*57)
Call Trace is used to help protect you and your family from troubling or harassing phone calls that you need to report to law enforcement officials. This service should only be used if you intend to take legal action against the caller.
If you're in the UK like us, *57 may not work for you. In these cases, it's best that you contact your phone company and explain that you're receiving nuisance calls from withheld numbers. They can stop withheld numbers contacting you, and they'll also be able to conduct a trace on whoever is attempting to contact you.

When you call a number that has blocked yours, you may hear one or half a ring or no rings at all and then the call will go to voicemail. If it goes straight to voicemail, their phone may also be off or out of range, or they may have temporarily turned on Do Not Disturb mode to work, drive, or sleep.
Android users may determine if someone has blocked their number by checking notifications. If the “sent” icon changes to “delivered,” the receiver is likely not blocked you. On the other hand, if it stays on “sent,” there's a good chance they have blocked your number.
