[InstaGC] Should I give them my address?

I was trying to redeem an amazon card for the first time on Instagc, but it said i needed to get access from the support center. The support center tells me i need to show ID or they will write a check. Only problem is I don't feel comfortable doing this. I don't want them to sell my personal info to advertisers or whatever (I don't use my actual address), and I don't have to do this with Swagbucks.

Am I just needlessly worried?
