There’s no foolproof way to stop identity theft, but the number one way is to freeze your credit. Frozen credit means no one can do anything new with your credit. They cannot open an account or make changes to current accounts that would require the creditor to check your credit. It doesn’t stop someone from stealing your identity in other ways, such as opening bank accounts in your name and/or draining your bank account, but it makes it harder to get a hold of your information.
