^^^ I disagree with this (at least for the First Class method I suggested). Nobody has ever had to put a phone number on the paperwork and packages always make it up here. (Nor has an invoice ever been necessary if you're fine with shipping uninsured.) I can't speak to anything sent via Global International, but that's not the option you want to utilize, anyhow.

My #1 suggestion to getting it done right is avoiding any sort of USPS "outlet" and take your package to a main post office branch. The knowledge (or lack thereof) of the outlet workers tends to be all over the place. I hear it all the time from my American friends and have definitely experienced it myself way too many times!
