What is the primary purpose of caller service?

The primary purpose of caller service is to provide premium services that include more flexible mail pickup times for businesses and individuals who require frequent access to their mail. This service is designed for customers who may not have a conventional delivery address or who prefer to manage their mail collection in a more controlled manner. By offering more mail pickup options, caller service accommodates the needs of those who require timely access to their mail, ensuring that they can manage their correspondence efficiently.

While other options refer to aspects of mail collection and discounts, they do not capture the essence of what caller service is focused on—enhancing the convenience and accessibility of mail pickup beyond standard delivery methods.
