Yes, easily.

It would take a phone call, since I haven’t set up the rails to do this. But “I need ten thousand sequentially numbered checking accounts with wire privileges” is a perfectly fine (if odd for an individual customer) request. (Almost any process requiring that many accounts is being done wrong.)

Granted, I have a private banker. But there are services who provide this to e.g. fintech companies setting up and destroying single-use accounts on the fly.
