Does anyone know how to sign up for a Nexon Korea account?

I've made one but it asks for a child KSSN and an adult KSSN, but it says that the parent KSSN must be 20 years older than the child, and when I try a KSSN that is over 20 years, it doesn't work but when i try one that is less than 20 years older it lets me go to the verification step but doesn't let me verify cause i get a message saying It needs to be 20 years older than child KSSN. If you would like to help me just PM me please and we can discuss more about this.

Thanks!

I saw someone, give me a minute.
Edit: Can't find where I saw him, but he said he's an expert on Nexon Korea.
I'll try googling your problem, alright?

For now, move this to Maplestory Help?





That's all I found
