2015 Career Ladder numbering system
Starting with the 2015 season, all teams competing in the Career Ladder would partake in a numbering system in which the teams could chose their own numbers and retain them throughout their time in the Ladder, regardless of the level in which they were competing. Teams could chose any number from #2 to #99, although teams competing in the Superleague were allowed first choice, followed by the Supercup and then Formula Challenge. Order of preference would be deemed by the finishing order of the previous season.
#1 would always be reserved for the reigning Superleague champion. As all Supercup and Formula Challenge champions automatically progress to the next series, #1 does not exist in either series anyway.
List of numbers and assigned teams for the 2015 season
The following list is incomplete and unofficial and will be subject to constant change until the process is completed.
Teams marked in italics have, at time of writing, staked a claim to a specific number, but these claims have been subsequently superseded by other teams with higher precedence.
