How the USPS Works
Every day about seven billion people would send the snail mail. Every afternoon they will collect all the mails and the boxes. First step is to separate them. The boxes go one way. The flat envelopes go other way and thick envelopes go somewhere else. There is a special machine which can sieve the thick envelope out. The next step is to bar code them. Every envelope has their unique code. It is like the ID for the letter. Then the computer would read the front of the envelopes’ address. The computer can tell the zip code and classify the envelopes. Finally, the local mails go to the particular post office. The other mails go to the plane or some other places.
I usually send the mails by USPS; however I had never seen this working process in the post office. I admire the computer can classify the letter by the zip code. The computer can deal with millions mails. It is really amazing. When I saw amount of letters in the post factory, I knew that the automatic computer is really important. If the post offices just have the people to handle the mails, I would take much time to send the mails.

ReplyDeleteWooohhooo!! That is amazing. I can't belive that is true,but there are a lot of risks to lose the letters. I remember when they lost one of mine improtant letter last year which I sent to California to change my status. That was horribale.
