Stamps.com has strict security controls in place to protect your information. One of the most common flags for a breech of security is five failed attempts to log into your account with the wrong password.
Issues with your bank account may also suspend Stamps.com, such as a chargeback from the bank or if the ACH payment for postage is rejected.
Be mindful of when you update your billing as well as this could have a similar effect. If you update your billing before you buy postage or if billing is updated twice in a row without a postage purchase between updates, a suspension could occur.
This suspension results in the inability to log into Stamps.com or purchase postage. When this occurs, you will need to reset your password. When you have successfully reset your password your suspension should be cleared.
