What role do barcodes play in mail processing?

Barcodes are essential in the mail processing ecosystem primarily because they help track and sort mail automatically. When barcodes are printed on parcels and letters, they can be scanned by machines at various points in the mail delivery process. This scanning generates information about the mail's location, allowing for real-time tracking as it moves through different stages of processing and delivery.

The automatic sorting process enabled by barcodes increases efficiency and accuracy, reducing manual handling and the potential for human error. Barcodes can also enhance the speed of sorting, as machines can rapidly scan and categorize large volumes of mail, ensuring timely delivery.

While barcodes may indeed assist in classifying outgoing mail or have other roles, their primary function within mail processing is centered around tracking and sorting rather than providing direct customer information or being utilized for advertisements.
