Each driver is able to choose their number during registration of their first event on MotorSportReg (MSR), providing the number is available. Please check the provided Permanent Numbers list on this page for availability. If registration for an event is not open yet and the driver wants to claim an available permanent number, it can be added to the list of permanent numbers by emailing the autocross steward:
This number is their number for the season. If you change classes, you must register a new number. All driver/class number combinations must be unique.
Note: this is only current to the last updated date shown at the top but any number row without a name listed in the name column should be an available number.
