The Car name is subject to the approval of INDYCAR and must not exceed 35 characters, including all spaces and punctuation. A Car may compete only in the Events in which the Car is entered. The Entry form must establish the Entrant’s right to enter the Car in the Event and include proof of ownership of the Car acceptable to INDYCAR. INDYCAR will use a Car number and Dallara assigned chassis registration number to identify each Car. Car Number – INDYCAR will assign to each Entrant License (not Driver License) a unique Car number. The Car number may consist of a maximum of two digits. No Car number may begin with the 0 digit. Car number 1 will be reserved for the defending Entrant (not Driver) series champion. All Car numbers are owned by INDYCAR. An Entrant may be granted the use of a Car number. All Entrants desiring a particular Car number must make a written request to INDYCAR.
