How is mail processed
The processing of mail involves several steps, from the moment it is deposited into a mailbox to the moment it is delivered to the intended recipient. Here's an overview of the mail processing steps:
- Collection: Mail is collected from mailboxes, post offices, and other collection points by mail carriers or postal workers.
- Sorting: Collected mail is taken to a mail processing facility, where it is sorted by zip code, city, or region. This is done using automated sorting machines or manual sorting by postal workers.
- Barcode Scanning: Each piece of mail is scanned with a barcode reader to capture the address information and track the mail's journey.
- Optical Character Reader (OCR): The address information is then read using an OCR machine, which converts the handwritten or printed address into a digital format.
- Data Entry: The digital address information is entered into a computer system, which updates the mail's tracking information and routes it to the next processing step.
- Automated Package Processing (APP): Large packages and parcels are processed using automated package processing machines, which weigh, measure, and scan the packages.
- Destination Sorting: Mail is sorted by destination, using a combination of automated and manual processes. This ensures that mail is sent to the correct post office or delivery point.
- Transportation: Mail is transported to the next processing facility or delivery point using trucks, planes, or trains.
- Delivery Point Sequencing (DPS): Mail is sorted by delivery point sequence, which ensures that mail is delivered in the most efficient order possible.
- Delivery: Mail is delivered to the recipient's mailbox or post office box by a mail carrier or postal worker.
In addition to these steps, mail processing facilities also perform various quality control checks, such as:
- Address Correction: Mail with incorrect or incomplete addresses is corrected or returned to the sender.
- Undeliverable Mail: Mail that cannot be delivered due to incorrect addresses, non-existent addresses, or other reasons is returned to the sender or processed through a special handling system.
- Special Handling: Mail that requires special handling, such as certified mail, registered mail, or mail with specific instructions, is processed accordingly.
Overall, the mail processing system is designed to efficiently and accurately sort, track, and deliver mail to its intended recipients.
