PERSONAL IDENTIFICATION NUMBER (PID)

You have been assigned a unique personal ID number that will be used around campus to identify you as a Columbia University student. This is your Student Identification Number or what we call your “PID #”. It is a ten digit ID number that begins with the letter “C”.

You can view your PID # by logging on to Student Services Online (SSOL) at https://ssol.columbia. edu

Please keep this number handy. In the future you will need to reference this number on all Columbia University documents (like registration, loans, etc.)
