2025 Race Numbers and Panels
The rules below describe the new standard for number panels.

301.3  Panel Numbers & Colors: Numbers shall be black on a yellow background, at least 5.5” (5.0” for Micro and Mini Swift) tall and have a 2 cm (.787”) wide stroke represented with an Arial font. No shaded or outlined numbers are allowed. The competition number shall be bordered by a yellow background of 1 cm (.393”) minimum. They must be in place prior to any official session, on both front and rear panels, as well as on both sides towards the rear of the bodywork. The driver is responsible for ensuring that the required numbers are always clearly visible to timekeepers and officials.
 


A popular example for individual numbers are shown above.  If your kart's factory decals provide yellow panels, then basic die-cut vinyl numbers are very cost effective.

2025 National Pro And Semi-Pro Class Champions

Pro Classes will switch from 3 digit National Plates to single digit, 1-3 starting at the 2024 Pro Tour. The top three finishers in the Semi-Pro classes will run their 3-digit national number plates as normal. Starting with the 2024 SuperNats and through the 2025 Pro Tour, Pro Classes will run National Plates 1-10.

Semi-Pro Plate holders can optionally run their single-digit kart number (1, 2, 3) on their front fairing only.  This can be a black number on yellow background, or yellow number on black background.  No other colors please. Their 3-digit kart number should be used on the sides and rear. The 3-digit numbers will be used on your tech sheet and in registration, scoring, tire/fuel desks etc.

Reserved Race Numbers

Please refer to the Membership page for information on reserving race numbers.

How do I choose my number?

When you sign up for your first race in any of our series, you will choose your number from available numbers in that class's pool. That will then be your reserved number for the rest of the year, in that series. Since you are picking a number for each series, it's possible you will end up with different numbers in different series. Numbers are always 'first come, first served' and we will not honor requests to 'hold' a number for you. 

Note: As the SuperNationals is considered a STAND-ALONE race, all race numbers will revert back to the FIRST COME, FIRST SERVED policy with no priority to competitors having run in the ProKart Challenge, Pro Tour, or Winter Series (Unless you purchased a number reservation at the beginning of the year).

Individual Numbers vs Custom Number Panels

Because of the possibility of you having a different number for PKC and the Pro Tour, for example, we don't recommend you purchase pre-printed number panels prior to race number confirmation from SKUSA. We also highly suggest using individual number decals that many of your favorite decal printers are now making. There will likely be 1 or more vendors selling them on site at all races, although we recommend sourcing them from your favorite shop or printer ahead of each event.
