The imei number is blocked so it's most like been reported lost, stolen or the original owner didn't pay the phone off.

Can i simply throw my old iphone boxes in garbage?
phone or the empty box?
Empty box
Toss them.
unless youre a box hoarder i would probably just toss it. theres usually a sticker that contains some of the phones info on it like IMEI etc that you could always cut out and put somewhere in case you need something physical with the numbers on it.
