What is my Swimmer's USA-S ID Number?
A 14-part number assigned to a swimmer by USA Swimming after they have registered.
The first 6 parts are numbers of a swimmer's birthdate: Month/Day/2-Digit Year using zeros as place holders. The next three spaces are the first three letters of the athlete's legal first name. The next letter is the middle initial, followed by the first four letters of the swimmer's last name.
For example: USA-S ID# for swimmer Suzanne Eileen Nelson and born Aug.27, 1976 is 082776SUZENELS.
