What is a caller service?

A caller service refers specifically to a standard service that provides customers access to a private mailbox, where they can receive mail and packages securely. This definition aligns with the function of ensuring that customers have a reliable way to receive mail at a location that may not be their home or office.

The choices regarding forwarding calls or providing more frequent mail pickups relate to different types of customer service and mail handling but do not accurately define what a caller service is. Similarly, allowing customers to call for mail delivery does not accurately represent the typical functions associated with a caller service. Understanding these responsibilities reinforces the importance of knowing various mail services and services that USPS provides.
