These codes are designed to streamline the sorting and delivery of mail by providing precise location information.
Typically, a postal code corresponds to a specific neighborhood, city, or district, enabling postal services to efficiently route parcels and correspondence to their destinations. The format and structure of postal codes vary from country to country, often reflecting administrative boundaries and logistical considerations.
