R2-D2, C-3PO... why doesn't 3PO use the format C3-PO, and/or R2 use R-2D2?
Does the formatting imply the kind of droid it is, or perhaps some other feature?

R2-D2 is an R2 series astromech droid produced by the company Industrial Automaton. All units of his model have names starting with the R2- prefix, including R2-KT, R2-Q5, and R2-B1. The same line of astromech droids also had different models, including the R1, R3, R4 and R5 units.
C-3PO, on the other hand, is a 3PO series protocol droid produced by the company Cybot Galactica. These models all use the suffix -3PO, but the first letter differs depending on their capability. Examples of this model include K-3PO, E-3PO, and U-3PO.
