Binance referral code back-fill tutorial BN522: can you still add it after registering? 30-day back-fill + 90-day recall + the $150k rule (2026)
How do you back-fill a Binance referral code? Can you still add it after registering? As of October 2026 there are three paths: a new account within 30 days of registration with no deposits or trades can back-fill; accounts with under $5,000 in trading volume over the last 90 days can submit a rebind application (and complete $150,000 in valid trading volume within 30 days of applying); accounts registered over 90 days ago that have been completely unused for the last 90 days can use the old-user recall. Accounts already bound to another referral code usually can't be switched. This article uses one decision table to help you find your situation.
