How do I find my alumni ID number?

1. Your Alumni Id Number can be found above your mailing address on Spark and many other Calvin mailings. You will find it listed as as 7-digit number, followed by your initials. Example:

9871234-jcc 1020304-ic
Mr. John C. Calvin
Ms. Idelette Calvin
In this example, John's Alumni Number is 9871234.

2. Try your old student ID number, which is the same as the alumni number for many (but not all) alums. If your student ID was less than 7 digits, add one or two zeros in front to make it 7 characters (e.g. Student ID 32154 = Alumni ID 0032154).

Your birthday MUST include the slashes and follow this format mm/dd/yyyy

3. Request your alumni ID number from the alumni office by sending an e-mail to with subject line "help me register." To help us verify your identity, please provide as much of this information as possible:

  • Full name (including maiden name)
  • Calvin graduation year / year left Calvin
  • Birth date
  • Major (if applicable)
  • Student ID number or last four digits of your social security number

What if I know my alumni ID number but the form is not working?

Please contact the alumni office at and provide the information in #3 above. We will verify your ID number and check that we have a birth date on file for you.
