<prompt> Human: Long story short, I have a check from my credit union Navy Federal to purchase a car from them. However, they keep insisting that they need to run my credit to purchase the car from them. They claim that they do this to all customers and is routine. I asked why they need a to run a credit check and they respond that they want to know who I am and if they can actually accept a check from me.I understand that there is a soft pull and a hard pull, but do they need to my SSN to verify who I am or are they trying to pull something off? I want to avoid another pull if I can.Edit: I live in the state of California if that makes any difference.Edit 2: It is a cashiers check from my CU  <response>: Tell them thanks for your time and head for the door.My guess is they will stop you before you get there.If they dont, shop somewhere else.
