How is dog read in the mail? - in detail

The term "dog" in the context of mail refers to a specific type of postmark or cancellation mark used by the United States Postal Service (USPS) on mail that has been processed through a machine, typically a high-speed sorter. This marking is known as a "dog bone" due to its characteristic shape, which resembles a dog's bone.

When mail is sorted and processed by automated machinery, the USPS applies these cancellation marks to indicate that the item has been handled by a machine rather than manually. The "dog bone" mark serves multiple purposes: it confirms that the piece of mail has undergone automated processing, it can carry routing information, and it helps in tracking the mail's journey through the postal system.

The use of these marks is crucial for several reasons. Firstly, they ensure that the mail is accurately sorted and directed to its correct destination. Secondly, they help in managing the flow of mail within the postal system by providing valuable data about where and when a piece of mail has been processed. Lastly, they enhance the efficiency of mail handling by reducing the need for manual intervention.

In summary, the "dog" mark in mail is an essential component of modern postal operations, facilitating automation, ensuring accuracy, and improving overall efficiency in the delivery process.
