When you want to remain anonymous, here's how

Caller identification is one of the best inventions of our time. Before its existence, you never knew who was on the other end of the line when you picked up the phone. A risky move, indeed.

Now a common feature on most home phones and virtually all mobile devices, Caller ID gives us the ability to screen calls and avoid annoying friends or pesky telemarketers. An obvious downside to this functionality, however, is that anonymity when placing a call is now a thing of the past ... or is it?

Thanks to the *67 vertical service code, you can prevent your number from appearing on a recipient's phone or Caller ID device when you place a call. On either your traditional landline or mobile smartphone, dial *67 followed by the number you want to call. That's all there is to it. When using *67, the person you're calling sees a message such as "blocked" or "private number" when their phone rings.

*67 does not work when you call toll-free numbers, such as those with an 800 or 888 exchange, or emergency numbers including 911. You should be aware that some recipients choose to block hidden or private numbers from calling them automatically.

Blocking Your Number on Android or iOS

In addition to the *67 feature, most cellular carriers offer the ability to block your number through Android or iOS device settings.

To hide your number when you use an iOS phone or another iOS device:

  1. Tap on the Settings icon on your device's Home screen.

  2. When the Settings interface appears, scroll down and select Phone.

  3. In the Calls section, tap on the Show My Caller ID option.

  4. If the button on the Show My Caller ID screen is in the green On position, tap it once so that it turns white, which is the Off position. Your outgoing calls will now display with the following message in place of your phone number: No Caller ID.
