I have refused to give mine out since
I do not go through insurance. I offered them my driver's license instead if they were worried about payment. Mine said never mind and let it drop. I do not know of any non-insurance reason to give it to them.

Probably just a part of whatever program she is using to database. I'm sure you could just say, "Sorry, for privacy reasons, I don't provide that info." My H does that all the time, like when companies try to use the last four of his social for a pin, he says he will not tell them and they need to make a different password, since so much private financial stuff is linked to that info.

I never give out my full SS#, only the last 4 digits. Seems to work for most people, including billing insurance. Insurance cards were switched over a few years ago from using the SS# to a combo of numbers and letters.

If she's not billing insurance, she should easily be able to have just the last 4 digits, or none at all.

She bills my trust fund and they pay all of my bills promptly. It sort of rubs me the wrong way that she is asking for my SS#. She is making $600 a week from me and is paid on time. She doesn't have to hassle with insurance or worry about a limited number of appointments. I'm not sure why on earth she could possibly need my SS#.

And I was clearly hesitant in giving her my SS#. I asked her, "Why do you need it?" and then after she responded I said, "Um......." hoping she would jump in and say "I don't need it" but she didn't, so I gave it to her. Maybe it was a test to see how much I trust her. ?? I'm just so surprised she didn't say that she didn't need it when clearly I was reluctant. I think it was a test. It had to be.
