If you have a telephone that can display caller ID information, you can choose whether to view information about a caller's identity before answering the call.

The caller's number may not be displayed, regardless of your setup, under the following circumstances:

  • Calls from outside the UK.
  • Calls from some other networks, including mobile networks.
  • Calls made from some payphones or made using a BT Chargecard.
  • Calls where the caller has withheld the calling number.

To check whether your telephone is set to display the caller's identity, dial *#234#.

To display the caller's identity on your telephone, dial *234#.

Note:

If you have a telephone that can display call waiting with caller ID information and you are in a call, if another call comes in, their telephone number is displayed at the same time as the call waiting tone is played.

To hide the caller's identity on your telephone, dial #234#.
