I entered ACE member code correctly, but my membership is not registered.

Please use one of three methods below. 

1. Users sometimes confuse reservation number (blue code starting with Y) with ACE member code. 
Please enter ACE member code (red code).

2. When purchasing ACE member code at YES24, if you enter your fan club member card number incorrectly, code registration is not possible. In this case, please cancel the purchase at YES24 and repurchase it, and register ACE membership with the newly issued ACE member code. 

3. If an ACE member withdraws from a community, an error may occur by being converted to standby status for withdrawal. 
At this time since the member is already converted to BASIC member, it is not possible to be converted to ACE member even though canceling the withdrawal and entering the purchased member code.
