If sending your package to a company, write its full name in this area or email the company to ask who you should address the package to.

Do your best to keep the street address on one line. You can write your apartment or suite number on a separate line if your address may extend onto two lines.

Place a white label over your package’s address and re-write the return address if it is smudged or sloppy.
