Not carrier but by packaging. My passport has been mailed and will be arriving within a week, and I am wondering how it will be packaged. I wonder because I want it to be a surprise, and my girlfriend checks the mail often and I don't want her to come across a giant package that says, "HERE IS YOUR PASSPORT! ENJOY TRAVELING!" You get my point. Is the package just a large envelope addressed from the department, or does it explicitly say what it is?
I'm sure I can get the appropriate answers here.
