If you do not know the identifier of the bank, you can use the bank search tool built into the Wire transfer details screen to locate the routing number of the payee's bank.
What if I want to send a Wire transfer but I don't know the recipient's bank ABA Routing Number? Please note that you will also be required to enter a security code when you need to add (or remove) a country in Global View ( My HSBC tab > Add or remove a country/region link). This code is generated using a slightly different method than the security code used to log on and create the wire payee, so ensure you follow the online instructions carefully. Also, a Transaction Digital Signing (TDS) code has to entered, for additional security, during the wire payee set up process. After that, you can send wire payments to existing payees without entering a Security Code logging in with their password is sufficient. You will only be required to enter their Security Code when you set up a new wire payee (domestic or international) and send them a wire for the first time.
