What is the first step the mail clerk must take upon returning to the unit mailroom?

Upon returning to the unit mailroom, the first step a mail clerk must take is to record all accountable mail. This is crucial because accountable mail, which includes items like registered, certified, and insured mail, requires special handling and documentation to ensure it is tracked and delivered securely. Recording this mail is essential for maintaining accountability and ensuring that the items can be located and verified as needed.

This step establishes a clear record of what has been received, allowing for efficient processing and distribution later on. If this step is skipped or delayed, it could result in the loss of important items or confusion regarding their status.
