Mail code

You're referring to the postal code or zip code!

A postal code is a series of letters and/or numbers used to identify a specific geographic area, such as a city, town, or postal district. The purpose of a postal code is to facilitate the sorting and delivery of mail and packages.

Here are some examples of postal codes from around the world:

• United States: ZIP code (e.g., 10021 for New York City)
• Canada: Postal code (e.g., M5A 1A1 for Toronto)
• United Kingdom: Postcode (e.g., SW1A 1AA for London)
• Australia: Postcode (e.g., 2000 for Sydney)
• Germany: Postleitzahl (e.g., 10117 for Berlin)
• France: Code postal (e.g., 75001 for Paris)

Postal codes are usually used in conjunction with a street address to ensure that mail and packages are delivered to the correct location.
