Do I need to sign for my iPhone 6?

My iPhone 6 just shipped and is scheduled to be delivered on Tuesday through UPS. Does anyone know if I'll have to be there to sign for it or will they just leave it?

It really depends on what time it is. I bought a Toshiba chromebook and we were home when it arrived, but instead of knocking or ringing the doorbell they just left it in the hall like halfway from our door. And that was UPS.
I think if it will fit inside your mailbox they'll put it in that.
