  • Use *57. One option to try to discover the identity of an unknown caller is a 57 call trace. Though this option does not work on all unknown calls, it does work on some so it's worth trying. To use it simply dial 57 on your phone and you will be given the previous caller's number.
  • Get an app There's an app for everything, including identifying unknown or blocked numbers as they come to your phone. One of the most popular is TrapCall. This app is available for both iOS and Android devices. It tells you the number of anonymous calls in real-time and can automatically block spam for you.
  • An unknown number could be because the caller has dialed *67 before the number to block caller ID, or it could be because the caller has requested that their provider block their number. It's more common these days that unknown numbers are scammers or telemarketers.
  • Enter *67. Enter the number you wish to call (including area code). Tap Call. The words "Private," "Anonymous," or some other indicator will appear on the recipient's phone instead of your mobile number.
