There is a format you must follow on an envelope including the order you write the address in as well as the placement. Make sure you use a dark utensil and clear handwriting when labeling an envelope. Also remember to pay the proper postage on the item.

Start with the name of the recipient. Address it with "Mr.," "Mrs." or "Miss," if applicable.
Write the building number and street on the second line of the envelope.
Write the city, state abbreviation and zip code on the last line.
