The process of displaying a calling party’s identification to the called party became commercially viable in the latter half of the 20th century. This technology allows recipients of phone calls to view the originating number before answering, offering a degree of control over incoming communications. A typical application of this functionality is to screen calls and avoid unwanted solicitations.
The development and implementation of this service stem from the need to manage increasing telephone traffic and provide users with greater agency over their communication channels. The benefits include reduced interruptions, increased privacy, and the ability to prioritize calls based on the perceived importance of the caller. Its introduction marked a significant shift in telephone communication dynamics, empowering users in a new way.
