What needs to be included in the endorsement of each mail?

Including the initials and date from the unit mail clerk in the endorsement of each mail is essential for several reasons. First, it serves as a verification step; the initials confirm that the mail has been processed or reviewed by the designated authority. This adds a layer of accountability to the handling of the mail, which is crucial in environments where accurate tracking of correspondence is important. Additionally, dating the endorsement provides a timestamp, indicating when the mail was handled. This information can be vital for record-keeping and tracking purposes, especially if any issues arise regarding the mail's delivery or processing.

In contrast, while stamping the unit address may seem relevant for routing purposes, it does not provide the same level of verification as the initial and date. The forwarding address alone is insufficient, as it does not acknowledge who handled the mail or when it was processed. Lastly, the sender's signature is not necessary for endorsement in this context, as the emphasis is on the mail clerk's processing of the item rather than the sender's confirmation. Therefore, the endorsement that includes the initials and date from the unit mail clerk is the most complete and functional option.
