Not sure about your Plate Number? If you purchased a General license and club membership, your plate number is based on your birth month and day. January 1 birthday = "101" October 22 birthday = "022". If you purchased a Race license and club membership, your plate number is the last three digits of your UCI ID on your license. If you earned a plate at Nationals in 2024, or Grands and Provincial Championships in 2023, that is your plate number for this season.
