How do I find out what my Stanford University ID (SUID) is so that I may register?

If you need your Stanford University Identification (SUID) number for site registration or other purposes, please see below. Your SUID is the original, unique identification number that you had as a student at Stanford. Non-alumni, such as parents of students, donors to Stanford, spouses and domestic partners of students and alumni, children of students and alumni, and faculty and staff members may also have SUID numbers.


  1. Please use our online Identification Information Request Form. You will be asked to answer several questions to verify your identity, and once your submission is received, a Customer Service Representative will send your Stanford University Identification (SUID) number to the valid, e-mail address you specify on the form. If you do not have a valid, e-mail address, or for some other reason are not able to use the above form, please see step 2.
  2. If you cannot the option above, please phone Customer Service toll-free at 1 (866) 543-0243 in the United States or (650) 724-0627 international, between the hours of 8:00 am - 5:00 pm Pacific time Monday through Friday.


  • Your Stanford Alumni Association account is tied to your SUID number. For this reason, you never need to re-register on the web site if you already have an account in our records. Simply use the Identification Information Request Form to request your existing username and password.
