When are notices for box rent service fee dues usually placed in PO boxes?

Notices for box rent service fee dues are usually placed in PO boxes on the first of the month. This timing allows customers to receive their notifications promptly and ensures they are aware of any outstanding fees as they begin a new billing cycle. This standardized practice helps maintain organization and consistency in the management of box rental services, allowing postal customers to respond to or resolve their dues within a clear timeframe. By issuing the notices at the start of the month, USPS allows sufficient time for customers to make payments before any potential disruptions to their service occur.
