How to address to a po box
Start the delivery address in the center of the envelope.
The name and address of the person or entity that the letter is intended for should go front and center. Putting these important pieces of information in plain sight will make the letter easier to sort and deliver.

Options: -If the delivery address is unclear or incorrectly placed, it's possible that the letter could be mishandled. Write the recipient's first and last name on the first line.; -Write: " po box 241120, suite 811, chicago, il 625578. " Fill in the day for delivery.; -If you're sending the letter out to just one person (from your own address), it may be easier to simply write out the recipient's name in bold. Many po boxes come in three basic sizes.; -The address should also go where the recipient/organization will see it-a secure location that is familiar to them. Mark the letter's title with a colored pen and a black marker.;
The answer is:
If the delivery address is unclear or incorrectly placed, it's possible that the letter could be mishandled. Write the recipient's first and last name on the first line.
