Tickets

The demand for tickets to Super Bowl XLI greatly exceeds our ability to accommodate the majority of our fans interested in attending. Most tickets are made available through the two teams competing in the game, and to a lesser extent through each of our other NFL teams. Remaining tickets for the general public are made available through a random drawing. There is no other means for the general public to purchase tickets. The NFL does not sell tickets to travel or ticket agents.
Entries for the random drawing are accepted between Feb. 1 and June 1 of the year preceding the game in question. All entries must include name, address, phone number and email address, and must be sent via certified or registered mail. You will be notified by mail in October or November if you are eligible to purchase Super Bowl XLI tickets. Requests for tickets to Super Bowl XLII, to be played Feb. 3, 2008 in Glendale, Ariz., will be accepted beginning Feb. 1, 2007. Requests should be sent to:
