If you receive a message saying your Easy Trade request was incorrectly submitted because of the account number, it means the U-number you entered does not match your Interactive Brokers account.
This guide shows you where to find your correct account number and how to fix your Easy Trade submission.
1. Open Trader Workstation (TWS)
Launch the Trader Workstation desktop application
Log in using your Interactive Brokers account credentials
💡 You can also view your account number in IB’s Account Management Portal at interactivebrokers.com.au.
2. Locate your account number (U-number)
Once you’re logged in:
You’ll find your account number in two places:
Top left of the home screen
Top right of the platform
It will be displayed as a U-number
This number uniquely identifies your trading account.
3. Use the exact U-number when submitting Easy Trades
When entering your account number in an Easy Trade request:
Make sure it matches exactly what you see in Trader Workstation
No missing digits
No numbers swapped around
No extra characters added
Even a small mistake will cause your order to be rejected.
4. Resubmit your Easy Trade
After confirming the correct account number:
Return to your Easy Trade form
Enter the exact U-number shown in TWS
Submit the request again
Once the account number is correct, your order should go through successfully.
Quick reminder
The account number used for Easy Trades is always the U-number displayed in Trader Workstation. Double-check it before submitting to avoid rejection.
