Amazon SSN/EIN Address Question

[HARDCOREHOLLY]

Ok, I have an account up and running and have sold some items. Everything is in my GF's name and she is ok with the tax part of it.

When I started the account I got a UPS Store box with a physical address. When I go through the Interview process for tax reporting questions its asking me for the Address. I don't want to use her real street address as its linked to another account. Will the IRS reject it if I use the UPS store address?
