GRE Registration Number for Older Exams

[hpjc]

So I took the GRE three times, and I want to send the score for the first (I did progressively worse..). Applications ask for the registration number of the exam I want to send, but the GRE site only has the registration number for the most recent exam. 

I called ETS and they say that their new "system" doesn't have registration numbers for exams prior to the most recent.. Has anyone else had this issue? I think I may have to contact the application committees to ask what I should do.

Emailing ets provided me with the registration numbers. The person on the phone did not know how to get the numbers.
