Indiana License Plates
Plates made to order on an individual basis after 2012 with no inventory carried at local plate offices. All plates mailed from Indianapolis after 2012. The "stickers" for the county name/number, expiration month, and expiration year were all screened on new plates after that point. Renewal date stickers still being issued in 2026.
The 2013-16 Bicentennial base reused numbers from the 2008 base upon renewal, continuing to make it very difficult to track highs. Indiana randomly issued the prior 2008 base, so tracking highs had already become impossible.
Plates were being issued in the 3 number/3 letter, 3 number/2 letter, and even 3 number/1 letter formats in each county. 3/3 plates have already been spotted from at least AAF through ZZZ, so obviously some combinations have been skipped, but there is no actual master allocation.
Drivers who previously had low numbers (1-100) in the traditional county coded plates were allowed to keep their number on the 2008 base by paying a $30 fee, which was less than the personalized fee.
Eric has documented the following observations about the 2008 issue:
In the 1-letter suffix, only A, C, F, J, K, M, Q, S, W, and Y observed.
In the 2-letter plates, all except M in the 1st position, and all but F in the 2nd position have been observed.
In the 3-letter plates, no X in the 1st position observed, but all letters in the 2nd and 3rd positions have been observed.
Based on the above, it appears they don't use I or O in the 1st letter position regardless of how many letters there are.
