What is VSC (Vertical Service Code)

VSC (Vertical Service Code) is a term used in telecommunications to refer to a set of three-digit codes that are dialed on a telephone keypad to access specific services or features provided by the telephone service provider. These codes are known as vertical because they are entered vertically on the keypad, unlike the traditional horizontal dialing used for regular phone numbers.

VSCs provide users with quick and convenient access to a wide range of services, such as call forwarding, call waiting, conference calling, voicemail, caller ID blocking, and more. Each VSC corresponds to a specific service, and by dialing the appropriate code, users can activate or deactivate the desired feature.

For example, to activate call forwarding, a user may dial *72 followed by the phone number to which calls should be forwarded. To deactivate call forwarding, the user would dial *73. Similarly, to enable call waiting, the user may dial *70, and to disable it, they would dial *71.

VSCs are not standardized globally, and their availability and functionality may vary between different telephone service providers and countries. Some VSCs may be universally recognized, while others are specific to certain providers or regions.

In addition to the commonly used VSCs, some service providers may offer specialized codes for unique features or services. These can include options like call blocking, call recording, speed dialing, and more. Users can typically obtain a list of available VSCs and their corresponding services from their telephone service provider or by referring to the provider’s documentation.
