How to block caller ID

Caller identification is a service that you are used to these days. You like to know who is calling before you answer. But do you also want to send your ID every time you make a call? If you do not, then this article will be useful for you to read.

Caller ID or caller identification is a service that is available as both an analog and a digital telephone service, which includes transmitting the caller's number with the ringing signal to the callee's device. If either your service provider of your phone is set to block your caller ID, then it will not be transmitted, as seen in Figure 1.

There are times, though, when you do not want to send your ID. This is when you block your caller identification in one of the following ways:

  1. In the menu of your mobile phone

    If you use a mobile phone to make that call, it usually has an option in its menu that says "Show Caller ID." If it is selected, then the ID will be shown, if not then it will be hidden.

  2. Special code

    You can use a code before the phone number. For example in the US and Canada, you should dial *67-310-555-9876 instead of 310-555-9876 to block your ID.

  3. Set it as default

    You can block your ID on all outgoing calls, if your request this service as default from your service provider.

  4. Use a third party service

    Then your call will be routed from another ID, so yours will not be displayed.

    • These services can be:
      • A pre-paid phone card
      • VoIP (voice over internet protocol) calling

  5. Voicemail

    Listen to the menu of your Voice Mail, wait for a call option, then dial.

  6. Public Phone

    Not hygienic, not comfortable, not private, but it also does hide your Caller ID, since you do not use your own device.
