Mobile dial code

A mobile dial code (MDC) is a grouping of 3 to 10 numbers following either a "#", "##", "*" or "**" used to create a short, easy-to-remember phone number. Historically, MDCs were used for repair-related purposes by landline and wireless carriers. More recently, MDCs have been made available for commercial use. MDCs are dialed just like a regular telephone number. Businesses can send automatic responses upon contact, such as by text message.
