Question
Is it legal to use USPS Priority mail boxes to ship via Global Priority mail?
Answer
I'm fairly certain it is. I recently shipped something Global Express and they had me use the regular Express forms. In fact, I'll go check, but I think on the old triangular tube Priority boxes, I think it said Global and one side of it. BRB
Sorry! I can't get to them--they're behind a huge pile of stuff in the garage. Maybe someone else will have one they can check.
Answer
Thanks for the effort. I decided to give it a try under the heading of better asking for foregivness than permission. Didn't work. The free Global Priority Mail are a different color than regular Priority Mail. I suppose they have a reason for that but the crew at the PO couldn't think of one and they are not interchangable.
Answer
They won't let us interchange them, either.
Heck, one time I had a Global Priority envelope that was being shipped internationally, and I stuck regular Priority tape over the flap, and they made me re-do it with clear tape.
Answer
nope, you have to use a Global priority package to ship global priority.
