Postal Code

A postal code, also called postcode, is a short code with the combination of numbers and letters. In some countries, the code only contains short numbers. In Germany, it is the 5-digit code written as part of a full residence address.

The postal code is primarily used as an indicator for a specific region. With the code, letters are easily sorted and delivered to the specified address quickly. In the United States, the term is known as zip code.
