I dont have to put the po-box when sending mail to schools right?

<p>can i just put the zip?</p>

<p>what would happen if i got the zip code right and po box wrong?</p>

<p>it wouldn't get there. think of it this way. the zip code tells the post office what neighborhood it goes to. but just the neighborhood. you need to narrow it down more than that for your letter to get there.</p>
