Question about guild

I made 2 people in my game and a guild for the first one, i want one of them to be in a different guild, how can I do that?

If you've made the 2 characters from the same account, they'll both be in the same guild.... as will the other characters you create from that account.

The only way to have them be in different guilds is if you have 2 accounts.

Can i make two different accounts with one verification code?

No, you can't.
