ISO 3166-2:AT

ISO 3166-2:AT is a system that helps identify different parts of Austria. Now, imagine that Austria is a big puzzle and ISO 3166-2:AT is like a special code that helps us figure out which piece of the puzzle we are talking about.

The code ISO 3166-2:AT is made up of two parts. The first part, "AT," tells us that we are talking about Austria. Just like the letter "A" might stand for apple, the letters "AT" stand for Austria.

The second part of the code is a bit more complicated. It helps us identify the specific part of Austria we are talking about. You see, Austria is divided into different regions, kind of like how a pizza is divided into slices.

Each region in Austria has its own special code that helps us figure out which region we are talking about. These codes are made up of letters and numbers. The letters help us identify the bigger pieces of the puzzle, while the numbers help us identify the smaller pieces.

For example, let's say we are talking about the region of Vienna in Austria. Vienna's code is "AT-9." The "AT" tells us it is in Austria, and the "9" tells us it is the ninth piece of the puzzle.

Now, let's say we are talking about the district of Innere Stadt within Vienna. Innere Stadt's code is "AT-9-1." The "AT" still tells us it is in Austria, the "9" tells us it is in Vienna, and the "1" tells us it is the first piece of the puzzle within Vienna.

So, ISO 3166-2:AT is like a special code that helps us identify different parts of Austria, just like a puzzle. It uses letters and numbers to tell us which piece of the puzzle we are talking about.
