What is a Common Short Code (CSC)?
A Common Short Code, or CSC, is a short code which is common across many wireless service providers in the U.S. It’s the inter-carrier connection for your mobile application. All CSCs are 5 or 6 digits in length and can be either random or select (vanity or easy to remember). The Common Short Code Administrator (CSCA) or www.usshortcodes.com assigns CSCs to applicants allowing them to be used for the same application across multiple wireless service providers. A CSC is often called a brand’s “mobile marketing address”.
