How can I find out which Regions Bank branch issued a cashier's check?

I’m trying to figure out which Regions Bank branch issued a specific cashier’s check. The routing number (062000019) points to a PO Box in Birmingham, AL, but under the signature line, it says ‘Branch MO05151,’ which seems to indicate a Missouri location.

I need to know exactly which branch issued this check. I’m not a Regions account holder, and there isn’t a Regions branch within 500 miles of me, so their customer service hasn’t been helpful.

Just curious, why do you need to know which branch issued it?
