For your viewing pleasure at home, the ninth and tenth digits/letters in an 18-figure UPS tracking number denote method of shipping. For example, 03 is Ground and PP is Basic.
Also, there are two UPS Basics, Basic 1 and Basic 2. I don't know the difference, and don't care...as long as it works.

I saw a movie where only the military and the police had guns. It was called Schindler's List.
