What information is typically included on tray labels?

The correct answer emphasizes essential information that facilitates the efficient processing and delivery of mail. Tray labels are critical in the mailing and shipping processes, as they assist postal services in tracking and sorting mail effectively.

Typically, tray labels include the destination of the mail, which indicates where the items should be sent. This is crucial for ensuring that items reach the correct location. The contents listed on the label provide details about what items are contained within the tray, helping postal workers to manage and sort items accurately. Lastly, including the origin is important as it reflects where the mail has come from, which can help in tracking and managing the logistics of mail delivery.

This combination of destination, contents, and origin enables postal services to optimize their operations, reduce errors, and improve overall delivery efficiency. In contrast, other options may include elements like weight or handling instructions, which are not as universally applicable as the three components in the correct answer.
