DB's just read the barcode (Delivery Bar Code Sorter)
Not in primary sort. I didnt want to list the process- just the end result of final destination.
After taking the letters getting them in facing all the same way through the collection machines, then it goes through a OCR which reads the address and sprays the bar code on the letter. Then it goes through the ISS which sorts it- if it cant it goes back through the LMLM ( pronounced lim lim") machine to re be read. If it fails it goes to manual operations. If it does read it, it goes back to the ISS then to the DBCS for foreign operations. ( I worked in a facility that we processed foreign mail as we were associated with the INternational airport..) This seperates it by country, then sent out. ON the receiving end, it goes through another DBCS to process to city under operation 891 then for street delivery to either two pass sort or single..
