I do not have a Social Security Number. How do I activate my account?


All students without US Social Security numbers are assigned a nine-digit ID number by their admissions office, and this is the number you need to use in the place of an SSN. If you don't know what this number is, you should contact your admissions office. (The number is NOT the one that starts with "C.")

If you are an employee, your department may have assigned you a temporary Social Security Number replacement. Please check with your departmental administrator for this number.
