Q: How do I find my PID?
A. Because it is not safe to use social security numbers for online forms and via e-mail, the University assigns each student a PID.
You must supply your PID in order to complete your course preference ballots.
All PIDs are C+9 digits.
Students receive their PIDs with their orientation materials and are asked to use them for all official electronic interactions with the University.
If you lose yours, please go to https://ssol.columbia.edu/.
Click on ACADEMIC PROFILE. You will see a screen with VIEWING OPTIONS at the top.
It will indicate that your personal information is hidden. Click on UPDATE VIEW and change the option to “show my personal information.” All your information, including your PID, will then appear on the screen.
