In this article, we will delve into the history and significance of the pound key, exploring its evolution, uses, and relevance in modern times.
The pound key, denoted by the symbol #, has a rich history dating back to the early days of telecommunications. Originally, it was used as a symbol for the unit of weight, pounds, in the British imperial system. However, with the advent of telephones, the pound key took on a new role. In the early 19th century, telephone operators used the pound key to signal the end of a dialing sequence, allowing callers to access various services, such as operator assistance or directory information.

In the 1980s, the pound key gained popularity with the introduction of touch-tone phones.

The pound key, in particular, was used to signal the end of a dialing sequence or to access special features.
