What is a Postal Code?
A postal code is a numeric or alphanumeric code used internationally to identify geographic regions for mail delivery. While the U.S. uses ZIP Codes and the UK uses Postcodes, every country has its own system of postal codes to simplify addressing and logistics.

- Germany: Numeric codes, e.g., 10115 for Berlin.
