The sequence of numbers followed by the operating system identifier relates to a short code. These short codes are commonly used to send and receive text messages for various services. An example includes receiving a verification code after initiating an account recovery process on a website through an application on the mobile device.
The employment of such numeric sequences provides benefits, including streamlining communication and facilitating automated processes. They are used frequently in marketing campaigns and for two-factor authentication due to their ability to deliver targeted information quickly and reliably. Originally, such codes enabled the delivery of value-added services via mobile networks, such as news alerts and ringtone downloads.
