Once it’s permanently deleted, you can't do whatever approximately reinstating your Pinterest account. However, when you go through all the steps to delete your account, you still have 14 days to change your thoughts. The e-mail you obtained from Pinterest to verify which you want to delete the account states this clearly. You can, at any point during these two weeks, log in with your information again. If you do, Pinterest will send you a reactivation email, and you can begin using the account as before.
