How to Write an International Address 

The first line of the address should be the recipient’s full legal name. This should include their first and last name and a comma after their middle name or initial (if any). It also includes the city, state and zip code. 

On the second line, write the recipient’s apartment or house number and street name. This can be written in either uppercase or lowercase letters, depending on the situation.

It is also necessary to include the building, administrative division and postal code. These will vary by country.
