Idaho License Plates

Idaho issues two plates for most vehicles but since July 1, 2025, front license plate display is not required if the vehicle is not equipped with a front license plate mounting bracket. If a front bracket is present, the plate must be displayed. Renewal date stickers are no longer required since July 1, 2026.

Idaho plates marked "PRP" along the left side signify a truck or bus operating in more than one jurisdiction as part of the International Registration Plan (IRP). Current series PRP plates have appeared with Ax (tractor), Bx (truck) and Cx (trailer) vehicle prefixes. PRP trailer plates not issued since 2001. Numbers and plate bottom darkened in 2008 when plates changed from embossed to flat. High PRP truck AM 8362 thin font flat plate with no stickers 7-14-26 MJ.

Idaho license plates have been on a rolling 10-year replacement cycle since 2020, a three-year increase from the prior seven-year requirement.

The current Idaho county-system passenger base debuted in 1991 as a blue-number embossed plate, later revised to all-flat in 2008 with black registration characters.

At the end of 2020, the serials following the county prefix started using a mashup of alpha and numeric characters, at first with a "U" suffix. In most populous Ada County, after 1A ZZZ9U was reached in 2025 they advanced to the V series at 1A A001V.

There is also a smaller motorcycle version available.

Flat since 2008. All colleges use this sequence that ends with S.

It appears that with the high amount of collegiate plates in circulation, the 9 at the beginning is a constant to avoid clashes with other types. The 9BxxS series appeared to have been omitted to avoid a clash with county 9B (Boundary). Progression appears to be in format 9lnnS, 9lnlS, 9llnS, 9lllS. Example 9A01S-9A99S, 9A1AS-9A9ZS, 9AA1S-9AA9S-9AAAS-9AAZS, 9AB1S-9ABZS, etc. then 9C11S..
