Your CalNet ID is your online identity at UC Berkeley. It will be used for system access log-ins and authentication, and it will be your campus email address when combined with @berkeley.edu. (For example, the CalNet ID oski.bear becomes oski.bear@berkeley.edu as an email address.)
-
keep it short -- you will be typing it often
-
keep it professional -- professors and future employers will see your CalNet ID in your campus email address
-
make it yours -- since your CalNet ID serves as your username in many campus collaboration systems, consider including all or part of your name
