Yep, anything sent registered thru USPS--you must use the brown gum tape.
I had to do that several times--on all seams.
In fact, bought a roll myself. Just wet it and stick it. Sometimes you get a nice clerk to do it in front of you at no charge with their tape.

BTW- My recent experience with FEDEX- i had a next day package for a small car part in a bag...They decided to put it on a windshield(under wiper) on one of my cars in the driveway. Lazy assholes!!!!
