Who do you want to create the account for?
Minors who are able to create an account in their own name are still required to have Parental Controls.
In certain countries, children under a specific age cannot own a Battle.net account. If you receive the error Unable to Process during the account creation, the Battle.net account must be registered to the name of your parents or guardians. The date of birth must also reflect the parents' or guardians' details.
