Plate Missing: Guanajuato was one of two states to release graphic issues first in 1995, with the first issue featuring a small logo at the bottom left of the old green-on-white federal issue.
Guanajuato undated passenger issue (1998 issue). I've always liked this issue a lot, it stands out quite a bit from the rest of the graphic plates. This issue has a green and blue background with white bead-reflective lettering. The state seal is seen on this plate as well, at the bottom left.
Guanajuato undated passenger issue (2001 issue). This plate takes a relatively simple approach, with gold and purple stripes at the top and bottom and a small state seal at the top left.
Guanajuato undated passenger issue (2009 issue). After an eight-year run for the previous issue, Guanajuato began issuing this new plate in 2009. The plate featres a graphic of the statue of Miguel Hidalgo, the "Father of the Nation" who was born in Guanajuato. The plate also commemorates the Mexican bicentennial in 2010 with a logo at top left.
Guanajuato undated passenger issue (2017 issue). New national standards were established by Mexico's Secretary for Communications and Transport starting in 2017, resulting in a flood of new issues. These standards dictate the placement of graphic elements on the plates, mostly restricted now to the top and bottom of the plate. Guanajuato selected a simple motif with their tourism logo at top center and blue band at bottom. The state implemented the new national ABC-123-A serial format starting with this base.
