without having to hunt down someone in HR

When I worked for UPS they specifically told me there was absolutely no way that HR would verify salary/employment over the phone for mortgage applications and the only way to do it was via theworknumber.com. UPS has ~500,000 employees so you can understand why they'd want to offload this work to a third party. I was working with a smaller mortgage company so they grumbled about having to do it this non-traditional way but it all worked out in the end.
