IIRA licenses are valid from the beginning to the end of a season/year.

An IIRA license is required to register for all wheel to wheel and track day events - weekend licenses are available for those events.

Holding an IIRA annual license makes you elligible to reserve a permanent number for racing events. Otherwise, numbers will be first come-first served based on order of registration. Reserved numbers will become available again after 1 season of non-use. To reserve a number, contact the event organizer. Click the "Have questions" button on this page and then "Questions for the event organizer" and let them know which number you would like to reverve for yourself.
