Got rear-ended a few days ago. I need more info from the other person. Should I reach out myself?

I got rear-ended around the corner from my boyfriends house. I got the person's name and insurance information, but didn't think to take her vehicle make/model. I know where she lives, since she was pulling out of her driveway when it happened. I think I've found her on social media. My insurance can't continue with a claim until they have that information. Should I reach out and ask? Is that awkward or tacky? How should I approach this situation? Physically I'm ok, but my driver's side taillight is a mess.
