What is the correct format for eTicket case numbers in 2010 and beyond?
In the past, eTicket case numbers began with the last digit of the calendar year (i.e., 7Y for 2007, 8Y for 2008, etc). JIS does not accept zero as the first digit of a case number, so this pattern will not work from 2010 forward.
The new pattern will use the Roman Numeral X to represent the year 2010. Beginning on January 1, 2010, an eTicket entered with the SECTOR program will be created with the XY formatted numbers (i.e., XY0000001 is the first case number assigned in 2010).
To prevent duplicate case numbers in succeeding years, the X will be replaced with the last digit of the year, and the Y will be replaced by the letter Z. This pattern will cover the years through 2020. (i.e., 1Z0000001 is the first case number assigned in 2011 and XZ0000001 is the first case number assigned in 2020).
Every ten years the second character in the case number will advance to the next letter of the alphabet and cycle back to the beginning after Z. The letter X will continue to be used as the first character of those case numbers in years ending with a zero. Here is an example of a decade of case numbers beginning with 2010.
1ZNNNNNNN = 2011 1ANNNNNNN = 2021 1BNNNNNNN = 2031
2ZNNNNNNN = 2012 2ANNNNNNN = 2022 2BNNNNNNN = 2032
3ZNNNNNNN = 2013 3ANNNNNNN = 2023 3BNNNNNNN = 2033
4ZNNNNNNN = 2014 4ANNNNNNN = 2024 4BNNNNNNN = 2034
5ZNNNNNNN = 2015 5ANNNNNNN = 2025 5BNNNNNNN = 2035
6ZNNNNNNN = 2016 6ANNNNNNN = 2026 6BNNNNNNN = 2036
7ZNNNNNNN = 2017 7ANNNNNNN = 2027 7BNNNNNNN = 2037
8ZNNNNNNN = 2018 8ANNNNNNN = 2028 8BNNNNNNN = 2038
9ZNNNNNNN = 2019 9ANNNNNNN = 2029 9BNNNNNNN = 2039
XZNNNNNNN = 2020 XANNNNNNN = 2030 XBNNNNNNN = 2040
