Asfa mail

You're referring to the Automated Surface and Air Mail (ASFA) system!

ASFA is a mail sorting and tracking system used by the United States Postal Service (USPS) to process and deliver mail and packages. The system uses a combination of automated and manual processes to sort and track mail, allowing for faster and more efficient delivery.

Here's a breakdown of how ASFA works:

1. Sorting: Mail is sorted at local post offices and processing centers using automated sorting machines. These machines read the barcodes on the mailpieces and sort them into specific bins based on their destination zip code.
2. Tracking: Once sorted, the mail is tracked using a unique barcode that is scanned at each stage of the delivery process. This allows the USPS to track the mail's movement and provide updates to customers.
3. Air and Surface Transportation: Mail is then transported to its destination using a combination of air and surface transportation. Air transportation is used for longer distances, while surface transportation is used for shorter distances.
4. Delivery: Finally, the mail is delivered to the recipient's mailbox or doorstep.

ASFA has improved the efficiency and accuracy of the USPS's mail delivery process, allowing for faster and more reliable delivery of mail and packages.
