Find out who owns a mobile short code in the United States. On June 6, 2007, Neustar announced that it has published the Common Short Code (CSC) Campaign Directory at www.usshortcodes.com. The only problem with the official directory is that participation by short code owners is voluntary. As a result, they will never have as many US common short codes in their directory as we do, assuming we stay up to date.

We maintain this directory as a public service.  We cannot guarantee the completeness or accuracy of this data.  If you see missing or incorrect information, please provide an update through the Directory Maintenance form on the Contact page. If you want to know how you get your own short code or leverage someone else's, tell us what you want to do on the More Information form on the Contact page and we'll steer you in the right direction. If you want to hear latest short code news as well as recent additions/changes to the short code directory, check out http://usshortcodeswhois.blogspot.com/, or better yet, sign up for our NEWSLETTER service.
