AMMC requires that all racers, (adult & youth) have a number that is specifically associated with their person and machine. Racers and machines must be clearly marked  in order for Race Officials to properly score. Racers may keep their number from season to season. You must renew your AMMC membership or register for the first race of the season to keep your number. Some numbers have been retired to honor past AMMC racers. Those numbers are not allowed to be used without prior authorization from the AMMC Board. Click here to view all of the retired racer numbers.

If you are a new racer and would like to reserve a number that is not already taken or retired, please contact us.
