Activating your UNI is one of the most important steps you need to take.

Your UNI (University Network ID) is the log-in name and password you will use to access many online services at Columbia. Your UNI is also the first part of your official Columbia email address.

To activate your UNI, visit http://uni.columbia.edu and select "Activate UNI or Email." Then follow the on-screen instructions.

Once you have successfully activated your UNI, you will be able to access Columbia's secure online applications, including Student Services Online (SSOL), CourseWorks, online library resources and much more.

Check Your Email Regularly

Your UNI is also the first part of your Columbia email address: [UNI]@columbia.edu. New undergraduates have LionMail, Columbia’s Google-powered email and calendar solution. To check your email, visit the LionMail login page. To learn more about using LionMail, please review the LionMail FAQs.

Columbia uses email as an official means of communication with students. Many important University communications, including notification of the Student Account Statement availability, are via email only. 

It is very important that you check your email often, as you are responsible for all official University communications sent to your Columbia email address.

For help activating your UNI, check out the CUIT help page.
