SSBI references and people who know you well

Recent college grad moved away at 18, I am 22 now. Going for job where i need SSBI. It is asking for people who know me well spanning the last 7 years. Problem with this is I do not talk to anyone from High School since I have moved away, all my college roommates and friends are from the past 4 years. Do I just provide contact information for people from the last 4?

Do your best and clarify if the investigator asks later. Nobody’s expecting you can just make people up for references.
