how to write address

To write an address correctly:

1. Start with the person's full name on the first line.
2. On the second line, write the house number followed by the street name.
3. On the third line, write the city name, state abbreviation, and zip code, separated by commas.

If the address includes an apartment number, add it after the street name on the second line, e.g., "123 Main St Apt 4B." The recipient's address should be centered on the envelope. Your return address goes in the upper left corner. For writing the address in one line inside a letter, include commas after each part, e.g., "John Smith, 123 Main St, Springfield, IL 62704." Make sure to capitalize every word in the address and use appropriate abbreviations for states and street types (e.g., St for Street, Ave for Avenue).
