Common Short Code Administration Announces Open Registration of 6-Digit Codes

WASHINGTON, D.C., 31 May, 2006 – CTIA – The Wireless Association® (CTIA) and NeuStar Inc. (NYSE: NSR) announced today that the Common Short Code Administration (CSCA) has opened registration for 6-digit codes on their website, www.USshortcodes.com. Common Short Codes (CSC) allow businesses and their customers to communicate directly with each other through mobile devices such as wireless phones and PDAs. The addition of an extra digit to the already available 5-digit CSC format enables an unprecedented number of new codes for brands to establish relationships with mobile customers. These easily recognizable and memorable codes are accessed using just 5 or 6 digits on the wireless keypad.

“The expansion of our CSC program is just another example of how wireless is revolutionizing the way we communicate and connect with the world around us,” said CTIA – The Wireless Association® President and CEO Steve Largent. “Only wireless can offer businesses the ability to meet their customers on the move and with this announcement even more enterprises can enter the game.”

Businesses that subscribe to and use common short codes have a unique advantage in being able to establish mobile-connected relationships directly with consumers, regardless of what mobile device or service a consumer uses to send and receive communications.

Examples of the kind of wireless communications that CSCs enable include consumer voting, marketing campaigns, direct downloads of ring tones and wallpaper, text alerts, and bill paying. The addition of 6-digit codes expands the availability of CSC to a greater number of direct interaction services for business brands, campaign managers, wireless communications carriers, special interest groups, and wireless users. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
