it depends im not sure about the particular bank

at my bank. 

if your pulled up in the internal program and it says your pre approved they dont pull your credit (how i got my 2k mastercard) it was just a new line. 

but if your pulled up in the teller system when you do a withdrawl/deposit etc. it will be a hard pull.
