How do you get money out of a bank account? im 16 years old?

Is the account in YOUR name, or are you added to someone's account. Unless you have your own account, newsflash, no one will let you make a withdrawal at 16. Now if you do have your own account with only your name on it, you should also have a debit card or an atm card that you can just take money out of any atm or get cash back at most stores. If you don't have the card or your parents didn't give it to you because they don't want you to spend the money you most likely didn't earn, your options are limited. You mentioned you have an account number. Do you have a checkbook? If so you can always write a check out to cash and get the money that way. And lastly if all else doesn't apply, you can always try going into the bank with your account number and filling out a withdrawal form they'll have ready at the front table when you walk in. Now if you have to do that you WILL be asked for your ID and if the account is not in your name, or if your parents have put any sort of restrictions on it they won't give you the money. But that's the worst of it, you'll just be turned down is all. Although it does sound like the account may not be in your name if all you have is a number.
