Hello @tvdwath1,
The best way to resolve this will be to get the IBAN number from your beneficiary directly. If they do not know it they can ask their bank for assistance. Note this IBAN will help to identify the receiver bank and where money should be sent. You can add your beneficiary on your Internet Banking profile.
Here is the link for more information regarding sending and receiving money abroad: https://www.standardbank.co.za/standardbank/Personal/Banking/Foreign-Exchange/Payments-and-transfers...
Let me know if this was helpful.
