For the better part of history, mail was delivered by hand or in person. Probably the most famous is Pheidippides who is said to have run from Marathon to Athens to deliver the news that the Greeks had defeated the Persians at the Battle of Marathon in 490 BC. Today, mail is sorted and processed using high-tech machines, such as the mail sorting machines engineered by NPI. Below, we’ll take a brief look at how mail sorting machines work. Contact us today!
Machines Separate the Mail by Shape and Size
Once mail reaches a central processing station, they are first separated by size and shape. Letters are separated from large envelopes and packages. This is called culling. The machine then orients the letters so they all face the same way with the right side up. The mail sorting machine also scans for postage to know it has been paid for and then applies a cancellation line so the postage cannot be reused.
Machines Scan for Bar or Postal Codes
Each mail sorting machine works a bit differently from others, but, in general, each piece of mail is then marked with a barcode or a postal code after it has been culled. The machines read these codes at high rates of speed and then begin the sorting process.
Machines Separate the Packages and Letters Based on the Barcode
Next, other mail sorter machines separate packages and letters based on the barcodes that have been applied that tell them delivery location. The packages are separated based on delivery, and a delivery barcode is applied.
Mail Ready for Delivery is Then Sent to the Carrier Location
The mail that is now ready for delivery is taken to the carrier location. The carrier then delivers the sorted mail to the appropriate address. The mail is automatically sorted for the carrier by address, which has saved hours on the carrier doing this manually.
