A mobile dial code (MDC) is a phone number that allows the request and receipt of information directly to a mobile phone. A mobile dial code combines a toll-free number, a web address and a short code into one simplified number. It is a 1-15 digit string of letters or numbers that is preceded by a combination of * or #. Mobile dial codes are dialed just like a regular telephone number. The caller can be presented with any one of a variety of responses that an advertiser defines - a voice or IVR call, a text message, a video or audio clip, a mobile coupon, game or an application.
