Caller ID, short for Caller Identification, is a feature that allows you to see the phone number of the person calling you. This can be helpful for screening calls, especially if you are expecting an important call or want to avoid robocalls. Caller ID is available on most landlines and mobile phones.
There are a few different ways to check caller ID. On a landline, the caller’s phone number will typically be displayed on a small screen on the phone itself. On a mobile phone, the caller’s phone number will typically be displayed at the top of the screen when the call comes in.
