UNI Activation & LionMail

Columbia University Email Activation

Once you submit the Acceptance Reply Form and tuition deposit you will be assigned a Columbia University Network ID (UNI), which will allow you to gain access to restricted library information on the Columbia website, student grades, and billing and registration information.

Once you confirm your intent to enroll in the Dual BA Program, you may check the Columbia directory to confirm whether your UNI has been created. 

Activate your University ID (UNI) and email (LionMail) account.

Follow the screen instructions to set up your email account.

Note: If you are not able to find your UNI in the Directory, please follow the instructions for "Can't find your UNI in the Columbia University Online Directory?"
