Can you still transfer money to a bank with just an account number (no routing number)?

Question

I tried transferring money from my school account to my bank. But my school account did not ask for the routing number (just the account number) before I sent my money to my personal bank.

Answer 1

No, routing # is required.  Did you give it to them before? Or if they know your bank the routing number is easy to find.

Answer 2

you must have already had the routing number of the bank on file, they must be asking you for the account # for verification purposes only, otherwise they would not be able to complete the transfer since your account # would only mean something to your bank
