How do mail processors use barcodes in their work?

Mail processors utilize barcodes primarily for the purpose of swiftly sorting and tracking mail items efficiently. Barcodes contain a wealth of information that can be scanned by machines to automate the sorting process. This technology allows mail processing facilities to handle large volumes of mail rapidly, as machines can read the barcodes and direct mail to the appropriate sorting bins or routes without unnecessary delays.

The use of barcodes not only speeds up sorting but also enhances the tracking of packages throughout the delivery process. As mail moves through different facilities and ultimately to the final destination, these barcodes allow for real-time updates regarding the status and location of the mail, providing both the postal workers and the senders with vital information.

In contrast, while ensuring that letters are sent internationally, determining the size of packages, and verifying addresses are important aspects of mail processing, they do not primarily rely on barcodes in the same efficient and systemic way that sorting and tracking do.
