What should be included when addressing an envelope?

When addressing an envelope, it is essential to include the recipient's name, street address, city, state, and ZIP code. This full set of information ensures that the postal service can accurately and efficiently deliver the item to the correct location. The recipient's name identifies who the envelope is for, while the street address provides the specific location, including any necessary details like apartment or suite numbers. The city indicates the larger geographical area, while the state and ZIP code are critical for sorting and final delivery, especially in a country like the United States where many cities share the same name.

Including just the recipient's name and email, the name with only a street address and city, or name with a personal note falls short of what is required for proper delivery. Email addresses are not useful for physical mail; omitting the state and ZIP code can lead to delays or misdeliveries; and personal notes do not provide the necessary addressing information for sending mail. Therefore, having complete details on the envelope is essential for successful correspondence.
