Each year, MCSCC members can reserve a permanent car number for the season. Once you have a permanent number, it will be reserved for you until April 15 of the following year (2 weeks after the start of the season on 4/1). You must renew your number each year in order to keep the same number. Requests can be submitted starting March 1st so you have roughly 6 weeks to renew your number. If you have not renewed your number prior to April 15, the number will become available for anyone to reserve it.
