Entered the wrong Binance referral code? Can it be changed, plus the recovery process, code BN522
Whether a wrongly entered Binance referral code can be switched depends on whether a referral relationship was actually bound: if the wrong code never bound, you can still go through the official back-fill path when eligible; if someone else's valid code did bind, the referral relationship cannot be changed or unbound once established. This article first shows you how to check your binding status, then lays out the recovery paths for the two cases — 30-day back-fill and the 90-day old-user recall — and warns that "internal re-binding" is a scam.
