New bases have "www.tnvacation.com" added to the area right above the County Sticker.
The current low on the new base is 096-BBB from Wilson Co. Dave Hermanson confirms that vowels are not used on the new base. Vincent Perillo reported 327-NFD in Nashville, which is almost certainly a continuation of the plates issued to members of the Nashville Fire Dept. as on the last base. He also reports 992-MPD, which corresponds to the previous issue for the Metro Nashville Police Dept. for their personal vehicles.
Upon reaching 999-ZZZ in 2011, the current format of A12-34A began.
New format low: A00-06A Knox Co. 2013-07-27 Ken Reager
Numbering Sequence: A00-00A, then A00-01A, etc. through A99-99A then A00-00B, A00-01B, etc. The letter Q is not used.
Some Z series plates are now showing up, but we don't know what they are for yet. If anyone finds out, please let us know. Ken Reager and David Wilson have seen Z series plates with TN FLEET stickers, so our best guess for now is that the Z series is for Fleet plates. These plates have been seen from at least 4 different counties.
Z high: Z58-35Z Williamson Co. 2015-09-16 Joshua Fickett
Ricky Rose reports that Tennessee began issuing just one validation sticker in July 2014, and it has the plate number on it, but Dave Hermanson updates that it is for selected counties only and is machine printed with the plate number and if necessary "Local Tax" also noted.
From Dave Hermanson: Additional counties are adopting new machine printed validation stickers along with registration cards. Knox County came on-line around the end of September. Exp. 15 stickers look nearly identical to the earlier serial-numbered style with the plate number centered at the bottom. TN is stacked in small letters on the right side and if local-tax has been paid TP is noted. This change will probably eliminate the additional Local Tax Stickers. Still issuing separate month stickers.
