Common Short Codes (CSCs) are short numeric codes to which text messages can be sent from a mobile phone. It’s very easy to remember and compatible with the leading mobile carriers. In a new report (pdf file) by mobile media research company M:Metrics, Common Short Code-based messaging campaign is mentioned as an “unprecedented platform for marketing”.

With more than 92.5 million mobile consumers actively sending and receiving SMS or text messages and accessible to 95% of mobile consumers, it offers the greatest reach advantage compared with other mobile marketing methods like mobile search, mobile web ads, and downloadable applications.

Other advantages offered by this method include low cost, easy to use, and proven effectiveness in mobile marketing campaigns across industries and business goals.

“In August 2007, 92.5 million, or 43 percent, of mobile subscribers actively engaged in text messaging. Of these 92.5 million mobile subscribers, 41 million send text messages almost every day. Not only is this number impressive as a stand-alone figure, but it is exponentially higher than the potential reach of the next available mobile advertising method,” said Evan Neufeld, vice president and senior analyst at M:Metrics.

CSC is expected to increase in the coming years given the increasing number of mobile users in the U.S. and their growing addiction to text messaging. In the latest report by CTIA, there are more than 243 million mobile subscribers in the U.S. or about 81% of the population. More importantly, these users are sending about 1 billion text messages every single day.
