The Postal Service is warning customers that their accounts may be closed if they do not make a payment on their account by the due date. Customers are also being warned that if they do not have a valid account number, they may not be able to receive mail. The Postal Service says it is doing this in order to improve its financial stability and ensure that all customers have access to their mail. The service has been struggling financially for years and has been forced to reduce its services and lay off employees.
