The dates, times, venues and prices for more than 600 sessions of competition across all 26 Olympic sports will be emailed to the 2.2m people who have signed up for information ahead of tickets going on sale on 15 March.
London 2012 chairman Sebastian Coe described them as the "greatest tickets on earth for the greatest show on earth".
The things people remember are head to heads and we could potentially have one of the best given that Tyson Gay is going to make this a really tough run for Usain Bolt
Double Olympic champion Coe said: "This is a really big moment, a huge moment.
"In my own experience as a competitor this is the point that it suddenly becomes very real.
"I remember this point in the build-up to Los Angeles, and suddenly realising I was going to be running seven races in nine days.
"We are now getting to the business end of the project and we know from the number of people who have signed up for ticket information that there is a real hunger from all parts of the country to be there."

Track cycling, dominated by the British at Beijing in 2008, gets underway at the velodrome on Thursday, 2 August with Sir Chris Hoy hoping to lead the hosts to gold in the men's team sprint.
The Olympic Stadium's track and field events begin on the Friday, with Ennis in line to begin her quest for heptathlon gold and finals in the women's 10,000m and the men's shot put.
Saturday, 4 August is already being dubbed as "Super Saturday" with the climax of the heptathlon competition and the women's 100m final taking prime-time slots. The Olympic rowing and swimming competitions will also reach a conclusion.
The following day features an equally mouth-watering array of sport, with Radcliffe and Ohuruogu hoping to be involved in the women's marathon and 400m final respectively, before a potentially electrifying showdown between Bolt and American Tyson Gay in the men's 100m.
Coe added: "We can already start to picture what might happen. There is a recognition now that the men's 100m is a pretty serious moment and we have planned that to be fairly early on the evening of that Sunday.
"The things people remember are head-to-heads and we could potentially have one of the best given that Tyson Gay is going to make this a really tough run for Usain Bolt."
