A postal service is a mechanism for transporting mail (letters and parcels) from one location to another. Nowadays, anyone can send letters almost anywhere in the globe.
Individuals who utilize postal services are charged in advance. Senders can make a payment by stamping their correspondence. People can also take their letter to the post office and pay a clerk or a postage machine there. The expense of sending heavier mail increases. Individuals can either drop off their letters and goods at the post office or put them in a mailbox.
Mail is sorted by size at the post office. Letters are run through a machine that removes the stamps. In order to prevent the stamps from being used again, the machine prints lines over them. The device also prints the date, the time, and the location of the stamping. This is called the postmark.
The mail is then sorted by postal personnel based on where it is heading (the place where it is going). They might sort it manually or with the use of equipment. Sorted mail is bundled by postal staff and placed in durable bags. The destination of the mail is indicated on these bags.
Mail is delivered by truck, rail, ship, or airplane by postal personnel. Mail can also go between nations thanks to cooperation among postal systems worldwide. Letter carriers deliver the mail to each address at the final location. Many postal couriers commute on foot or in little mail vehicles.
