Postal Codes

**Postal Codes** are alphanumeric codes assigned to specific geographic areas or addresses to facilitate the sorting and delivery of mail. These codes help postal services efficiently route and deliver mail by identifying specific locations, such as cities, towns, or neighborhoods. Postal codes vary in format and structure across different countries; for example, in the United States, they are known as ZIP codes, while in Canada, they use a combination of letters and numbers (e.g., K1A 0B1). The use of postal codes improves the accuracy of mail delivery and enables various services, such as location-based marketing and demographic analysis.
