Auxiliary Code Breakdown

The auxiliary code is the first two characters in the serial number. The first character indicates the year. Years progress or regress in alphabetical order. The series runs from “A” through “V” and the letters “I” and “O” are skipped. The second character indicates significant part changes within a year. Base is “0” and this number advances for each change.
