Address formatting refers to the standardized way of writing addresses to ensure they are clear and easily understood. This includes the arrangement of elements such as the recipient's name, street address, city, state, and postal code. Proper formatting helps postal services deliver mail accurately and efficiently. Different countries have specific address formatting rules. For example, in the United States, the street address typically comes before the city and state, while in Japan, the order is reversed, starting with the postal code. Adhering to these formats is essential for successful mail delivery.
