Zip codes and postal codes help mail arrive. But they work differently. Zip codes are common in the U.S. Italy has postal codes. This article explains how they differ. Knowing the difference helps when mailing letters. Each country’s system is unique.

What Are Zip Codes?

Zip codes help sort mail in the U.S. The numbers tell where the mail goes. A zip code has five digits. Some have extra numbers, like 12345-6789. The first number shows the region. The last numbers get more specific. For example, 90210 is in California. Adding more digits gets the mail faster.

When people move, zip codes change. I once moved from Ohio to Texas. My zip code changed, but my address stayed similar. It made my mail arrive in new places.

What Are Italy Postal Codes?

Italy. uses postal codes for mail. They call them CAP (Codice di Avviamento Postale). CAP codes have five numbers too. They start with the region’s number. For example, Rome’s postal code is 00100. Florence has 50100. It helps divide the country.

An example is sending a postcard. I visited Italy and sent one from Venice. I had to write the postal code to make sure it arrived. Without it, my postcard could get lost.

How Do Zip Codes and CAP Work?

Zip codes and CAP codes both sort mail. But they work a bit differently. Zip codes divide the U.S. into areas. CAP codes divide Italy into provinces. The systems fit each country’s needs. Italy’s towns have unique codes. In the U.S., zip codes can cover larger areas.

For example, a small town in the U.S. could share a zip code with nearby places. In Italy, a town’s postal code is more specific. I remember sending a package from Chicago to Milan. Both codes helped it arrive fast.

Why Is the Difference Important?

Knowing the difference helps send mail. Mailing something from the U.S. to Italy requires the right code. A wrong zip or CAP can delay delivery. When I ordered shoes from Italy, I used my zip code. But the store needed my postal code for international shipping. This mistake delayed my package.

Using the right code avoids problems. It saves time and stress.
