In mail processing, which element can lead to service delays?

Mislabeling and incorrect addressing are significant factors that can lead to service delays in mail processing. When mail is not properly labeled or addressed, it can cause confusion in the sorting and delivery process. Postal workers may struggle to determine where the mail should be sent, which could result in longer handling times, misdelivery, or even the need for return to the sender. Clear and accurate labels are essential for efficient processing, as they enable the postal system to quickly and accurately route items to their intended destinations. This highlights the importance of proper labeling and addressing in ensuring timely mail delivery and minimizing disruptions in the mail flow.
