I used to work for a multi national company until 2015.  I worked in technical field first and then as a Project Manager for over 13 yrs.. Screening me thru work was super easy, but that doesn't mean I gave out my work info. In fact I never did.. Back when I started, screening wasn't this invasive.  

 
In 2015, I quit my IT  job to take over and grow family business since my dad was retiring.. It's almost impossible to honestly screen me using my work info. There is no HR. It's a small business, and I run it. Are you going to ask one of my employees if their boss is the the one who he says he is, or are you going to ask for my tax return? LOL.  

 
I work out of my condo.I do have a home office, that has nice desk, docking station for my MacBook, a printer, scanner, flat screen TV to keep my brown ass amused. No one comes here. .Entirely everything else is done remotely / virtually.   So I use the same place for an occasional drink and an afterwork joint. LOL After 6:00 PM or so, my place will smell like Fremont street, I can guarantee you that.

 
Case in point.. Some of these bitches are stupid.

Those cases would be similar to your situation. As far as I know, almost every provider has alternative verification methods other than employment.
