They require more info than the routing number and you will have to call the local branch or contact the banks international transfers dept. I suggest calling the hotline over the local branch, usually they are clueless, but then again they might be able to connect you through without waiting. Or they can give you the correct # to call.
When I sent stuff to Europe all the time I had to get the swift code (bank ID in the system) and IBAN number (this was like their routing and acct #)
Also they will charge you a fee to receive the wire ($45 is normal).
And try to check the spot rate when you are on the phone with them.
