Anecdotal but I've heard that when banks auto generate PINs for debit cards they filter out some suspicious ones like 0000 or 1234 because it only leads to customers complaining and wanting to change them (more work for the bank). Nowadays the customer can usually change them themselves, so it might be less true.
When I got my credit card (and credit account) set up, they had me set a pin then and there. But that might be because I had to create the account in person?
Maybe they can, but it may not be free.
Up until a few months ago my bank used to charge €5 for PIN change at the ATM (unpaid accounts only).
