Short codes are mobile numbers that are significantly shorter than regular mobile numbers (usually 10 digits) which are used for SMS, MMS and Interactive Voice Services. The idea behind short codes is to make them easy to remember. Short codes are used for buying content, interacting with a menu, voting on TV programmes, listening to mobile radio/music, and a host of other services. Telecom operators, VAS service providers and TV channels use Short Codes for generating revenue.
