<prompt> Human: I think this is on the side of PF since it involves my SSN. Why would they need it? Im registering with a new doctor office and on the form they want my SSN and my Boss contact information. It sounds like theyre being overly nosy. Do I have to give it to them? This is a unnecessary risk, isnt it?If this is the wrong subreddit, please recommend another. SSNFinance to me.EDIT: Wow, lots of quick and good answers. For reasons I should have thought of. Prescription history. Insurance verification. Credit reporting if I dont pay. Thanks all!  <response>: I never put my SSN on a doctors form, and I have yet to be refused service. Primary reason is to make life easy for the debt collector if you dont pay. But I guess now that we are in a post-Equifax world, I might as well give my SSN to anyone who wants it...
