Those who sign up to tickets.london2012.com will be among the first to find out when tickets go on sale in spring 2011 and how to apply for them.
The site enables users to indicate which sports they are interested in and receive updates on major events and developments.
Some concerns, however, have been raised about Locog's harvesting of personal data.
Liberal Democrat London Assembly Olympics spokesperson Dee Doocey thinks the information being collected by Ticketmaster on behalf of Locog goes well beyond what is necessary to keep people updated about the 2012 Games.
"There is no reason to make it mandatory for people expressing an interest in the Games to have to provide their address, phone number and their age," she said.
"Most of the information they are asking for is totally unnecessary to keep people updated. The information they are harversting is gold dust and would be worth a fortune if it had to be obtained in the commercial market.
"I have written to Locog asking them to instruct Ticketmaster to cease collecting anything other than the minimum information necessary for their ticketing strategy."
75% of the overall 10m tickets will be made available directly to the public via a ballot process.
More information on pricing and availability will be issued later this year once the competition schedules and venues are confirmed.
