When writing an English address, it is important to follow a specific format in order to make it clear and easy to understand. The most basic format includes the recipient's name, street address, city, state or province (if applicable), and country.
For example:
John Doe
1234 Maple Street
Beijing, Beijing
China
It is also important to use proper abbreviations for countries, states, and cities. For example:
USA - United States of America
NYC - New York City
If sending mail to a specific apartment or suite number, include that as well.
In addition, if sending internationally, be sure to include the recipient's country code and an international postmark.
Remember to double check your spelling and grammar before sending your letter.
