How old do you need to be to open a bank account in Alabama?

If you want to open an individual account then you must be atleast 18 years old. But, if you are a minor (less than 18 yrs.) you can always open a joint account with any of your adult family members like mother, father, elder brother etc. banks do not say no to any customer who wishes to open a bank account (Unless they have a valid reason because the customer is bankrupt or has criminal record etc.)
