Reference is your account number at IBKR, account number is also unique to you, then routing just follow.
In your screenshot got the details liao if u notice. I notice the address is missing now after choosing in IBKR.. But should be allright if use Ziet address. They likely remove it from the website maybe is extra info only. Most important acc number routing etc will able to deposit the money already. So far I send like this all ok.

Account type at Wise choose send to Business/organization, then choose "checking". Address also follow what Ziet mentioned in his video. Pause his video if he too fast till u get it.





For Wise to IBKR transfer make sure u keep all your receipt. Because the fund is coming from 3rd party which is Wise. Got ppl kena audit from IBKR before where they ask him where the fund came from and show proof is his own money. If transfer from CIMB SG to IBKR then no need worry.

I use Wise to IBKR also coz easier. I keep all my receipts: maybank to Wise, Wise to IBKR in my Dropbox folder so phone also can access.

Once u succeed do this once.. Can repeat same transfer again by saving it in Wise for next time.. So don't have to retype all over again. After first transfer u will confident liao. First time only hard, later is easy peasy.

If you scare, transfer small amount like few bucks first. Once confirm went through then transfer bigger amount. Will need +1 biz day before IBKR will update your account for fund receive.

In IBKR setting make sure change fee rate to Tiered instead of Fixed. Default is Fixed rate which is more expensive for most of us.
