What is postal code meaning?

In many countries, the postal code is mandatory to include in your address when sending any mail. The format of postal codes varies from country to country and may have different lengths and patterns. In some countries, the postal code is based on the geographic location of the recipient, while in others, it is entirely arbitrary.
