Caller identity, also known as caller identification or Caller ID, refers to the feature in telecommunications that displays information about the calling party on the recipient’s device before they answer the call. This information typically includes the caller’s phone number and sometimes the caller’s name or other identifying details. Caller identity is commonly used to help recipients decide whether to answer the call or not, as well as to provide context about the caller’s identity.

Caller identity works by transmitting a set of data along with the call, which is then processed and displayed on the recipient’s device. The data can include the calling party’s phone number, which is often cross-referenced with the recipient’s contacts to display a corresponding name if available. In some cases, businesses and organizations may also use caller identity to display a recognizable name associated with their entity, helping recipients identify the source of the call.

Caller identity has become a standard feature in most telephone networks, including both landline and mobile networks. It provides several benefits, including the ability to screen calls, avoid unwanted or spam calls, and personalize the communication experience. However, it’s important to note that caller identity information can sometimes be manipulated or spoofed, leading to issues with spam or fraudulent calls.

In recent years, advancements in technology and telecommunications have led to improvements in caller identity features, such as real-time call verification, enhanced caller details, and integration with various communication platforms. Additionally, some regions have regulations in place to ensure the accuracy of caller identity information and to protect consumers from fraudulent practices.
