How can i get the number or email to HR at this location?

You can Google the ERC for amazon which is the Employee Resource Center and give them which Amazon you need the information from. I've been with Amazon since 2015 in different locations and states. The ERC is where you can get the information you need. Hope this helps

Im just wanting to get verification of employment...dates from when i last worked

I am an employee and I can't get one lol. It's automated. If you want to apply I would google "amazon hiring events" for days they are processing. I think they are doing it several days a week at least.
