Caller ID is a telephone service, which provides the calling party's number to the called party. The service may also provide a name associated with the calling number. It is often called CLID (Calling Line Identification or CLIP (Calling Line Identification Presentation). When Caller ID information is provided by a VoIP service, it is sometimes called CNAM (Caller Name). The calling party's information is transmitted to the called party's telephone equipment when the call is set up. The information may be displayed on a display device attached to the called party's telephone or on the called party's telephone itself. The information may also be announced by an automated voice announcement system

There are three different types of Caller ID:

1. Basic Caller ID displays the name and number of the person calling.

2. Enhanced Caller ID also displays the location of the caller.

3. Premium Caller ID includes all the features of Enhanced Caller ID, plus it allows you to block unwanted callers and see the last time someone called you.

The best way to change your caller ID is to contact your phone service provider and ask them to make the change. If you have a landline, this may be as simple as asking them to add or remove your name from the public directory. If you have a mobile phone, you may need to change your settings in order to display your new caller ID. You can usually find these settings in the "caller ID" or "phone number" section of your phone's settings menu.

There are a few ways to trace a cell phone number, but it is important to remember that most methods will only work if the phone is turned on and in range of a cell tower. One way to trace a cell phone number is through the use of a reverse phone lookup service. These services maintain databases of phone numbers and their owners, and they can usually provide information on both landline and mobile numbers. To use a reverse phone lookup service, simply enter the cell phone number into the search box on the website.
