I meant fake as in not your true sending address, not something like 123 Fake Street... for obvious reasons. It really depends on the circumstances. You just want as much deniability as possible. But perhaps I'm being overly cautious. I've generally used a friend's address instead of my own when shipping.

All overnight mail is first class. First class and express are the only ones sealed from postal inspection, yes other classes are subject to random searches. That is why I recommend overnight when it is something of questionable legality such as this. Yes, warrants are near impossible to get for packages. It's hard to show cause for opening or searching a parcel. UPS and FedEX are exempt from this because the protection from unlawful searches does not apply to private protection, only from governmental.

But Weezard is right, packing it as sealed tight as possible so it isn't obvious what the package contains.
