What is a Postal Code?

A postal code (also called ZIP code, postcode, or PIN code) is a series of letters, digits, or both assigned to geographic areas by national postal authorities. They help sort and route mail and packages efficiently. Formats vary widely — US ZIP codes are 5 digits, UK postcodes combine letters and numbers, and some countries use no postal codes at all.
