MSA Registration Number
From MSQ eReference
Each member of a Masters Swimming Australia affiliated club is allocated a unique six digit registration number. An athlete should keep the same registration number for life, even if they are not a member for a number of years. Numbers are allocated by Masters Swimming Australia when the member first joins an MSA affiliated club.
When entering a meet, Team Manager Entry files should not contain the athletes MSA numbers. These should be listed in the Summary sheet, if used. The Meet Recorder matches athletes with MSA numbers using the Registration RE1 File.(See Import Member Registrations)
