Student identification numbers are used to access content within my.SDSU, including student information and student records. 

As part of the my.SDSU transition, our campus has adopted a new identification numbering system.

Faculty, staff, and students who entered the SDSU system before Fall 2023 will continue to use their RedID Local Campus ID, an identification number beginning with 8, to access university services. These populations will also be assigned an EmplID, an identification number beginning with 1, which is affiliated with my.SDSU. Previously issued RedID numbers will remain in my.SDSU.

Faculty, staff, and students entering the my.SDSU system after Fall 2023 will only be assigned an EmplID. 

All faculty, staff, and students also have an SDSUid, which is the same as the SDSU email address.

This guide will cover how to look up a student’s RedID, SDSUid, or EmplID in my.SDSU.


1. Go to and select my.SDSU - Login Here on the top right of the page.
