Explanation

The term postal refers to an official, government-run mail service that delivers letters and packages right to your door or mailbox. Postal workers sort mail at post offices, sell postage stamps, collect packages to be delivered, and deliver the mail. When you're sending a package or letter to someone, you should include the correct postal code — also known as a ZIP code in the U.S. — in the address to help make sure it gets to the right place. The postal system connects people across towns, cities, and even countries by working to get letters and parcels to their intended destinations.
