The initial issue of these plates starting in February 2011 were issued in order from the AA to the DM suffix.
All of the teams used plates in the same series - numbers were assigned as needed.

In late 2014, several new suffix combinations started appearing,
and plates have been spotted ending with Ex, Fx, Gx, Jx, Lx, Mx, Nx, and Px.

The newer plates are split up by team - one team per letter (except for the 76ers/Knicks).

GIANTS plates (E series) moved into the D series in late 2024.
After they reached R/M 99EZ, they 'flipped' to the R/M DJ10 series.

The Rx and Ux letter combinations were used for NASCAR plates starting in late 2014,
after the AA-DM suffix letters were used randomly.

The LAST LETTER on the R- series plates indicates the type.
I just figured this out.   (How did I not see it before ??)

This section was added on Oct 6, 2026.

These are plates which are no longer issued (as far as we know).
The high sightings for these plates can still advance ... every once in a while,
someone will see one on the roads - or on eBay!!

These are plate types that have been seen on the flat base, but they don't come in sequential order.
There can be remakes, vanities, courtesy plates, special plates, government, dealers, and a handful of others.
