A machine called a Multiline Optical character Reader/sorter MLOCR for short, employs a camera and software to read the address on a letter. It is designed, hence name multiline, to read multiple lines of an adddress and consult a database of US addresses and match it to the delivery point code (DPC), or 11 digit barcode, Those short and long bars at the bottom of an address represent the Zip Code, the +4, and the last 2 digits of your street number, and a check digit. Many of you are correct that the city is not needed to lookup the correct DPC but often Zip Codes are wrong and hence another element, such as the City is needed. My company makes these MLOCR sorters for private mailing companies and many foriegn postal services.
If anyone has any other questions please PM me.

Good morning Pineedles, thank you for that very informative post! I do know that machines read barcodes for shipment, I print most of my shipping labels off on the computer, and of course it seems like most mail has a barcode on it now.
But what happens when a person writes an address by hand ? Is it true that those go slower in the mail, because a real human
has to read it ?
