Yeah, I think it is on there. It might be real little down at the bottom or something. Anyway, IF you have an ACT ID instead of your SSN, it is just the last eight digits of your match ID, plus a dash at the beginning. So if your match ID is 00123-45678, your ACT ID is -12345678.
I called the info number when I could not retrieve my son's scores. I provided the person at ACT with his SS# and verified additional info before they told me my son'e match ID#. I went back to the web sight and had no problem retrieving his scores (paying the $8.00 fee).
