I've come to this page because I do work for a software company that sells HR software that interfaces with payroll systems, and I'm documenting how to fill in workers' addresses. We have both a residence address (physical address, please) and mailing address. When I first started at the company, however, I lived on a sailboat where I could not receive mail, and it was a real pain. HR required my physical address (I used my mother's address in another state) and then sent important paperwork there, and I had to figure out how to get it. (We weren't using our own software then.) I definitely feel everyone's pain.
