Why is my routing number showing up as a different bank then the one I bank with? When I enter my account and routing numbers, the bank shows up as Bank Y instead of my normal Bank X.
Assuming there is no mistake, many smaller banks contract services like electronic transfers, check processing, debit cards, and even investments to a larger bank. The large bank is called a correspondent bank or a banker's bank. The name of the larger bank will show up as money is actually going through them.
This is very prevalent in credit unions as well, here the large bank is called a corporate credit union.
