How do I enter an Interactive Brokers referral code during sign-up?

Entering an Interactive Brokers referral code is straightforward, but timing is critical. You must input the code during the account application process—there's no way to apply it retroactively. When filling out the online form, you'll reach a section labeled 'Referral Code' or 'Promo Code.' Simply type or paste the code exactly as provided. Double-check for typos before proceeding. After submission, you should receive a confirmation that the code was accepted; if not, contact IBKR support immediately. The code typically grants a cash bonus, reduced commissions, or free trades, depending on the current promotion. Remember, missing this step means forfeiting the bonus entirely. So, before you hit 'Submit,' ensure the code is entered correctly. This small action can save you real money on trading costs.
