It’s Number Day!
Join us in celebrating a day taking a look at all things racing numbers on Trading Paints.

Today is 8/3 (we know, we know — it’s 3/8 in much of the world, but 8/3 looks like the Number Builder logo), the first-ever Trading Paints Number Day. Throughout the day, we’ll be celebrating all things numbers in iRacing (and surely having a great time playing around with Number Builder).
Here’s what’s on deck for this Number Day.
Giveaway: What’s your racing number?
Everybody’s car number has a story, and we want to know why you picked it. Share the special meaning of yours with us on our Instagram post. We’ll randomly give away some credits to the Trading Paints Store.
Most popular Custom Numbers
We’ve crunched the numbers (lol) and these are the most popular Custom Number paints assigned to Trading Paints since their introduction in 2019.
10th most popular: #17
With 62,626 uses, the #17 barely cracked the top 10 over #18, the 11th-most-popular number.
9th most popular: #24
Yeah, this one makes sense. Raced 66,345 times, there must be an awful lot of racers doing their best Gordon (or William Byron, for these modern times) impression.
8th most popular: #7
Seven is a lucky number. At least that’s what somebody thought 67,728 times over.
7th most popular: #88
To be honest, this one surprised the Trading Paints team; we thought it was a surefire top-three number given the unstoppable force that is JR Nation. Alas, there are 67,861 paints bearing the #88 on Trading Paints.
6th most popular: #3
Another number we expected to rank a bit higher with 74,346 total uses. They’re doing it for Dale.
5th most popular: #2
Two is a good number. It’s humble. You aren’t like the braggadocious #1; you’ve got to prove yourself. A total of 74,751 #2 paints live on Trading Paints.
4th most popular: #9
There’s quite a jump from fifth to fourth on our list: 84,963 paints — over 10,000 more than the #2 — bear the #9.
3rd most popular: #8
OK, maybe this is where 85,855 of JR Nation painters went — their ranks splintered between the #88 and the #8. (Or maybe they’re just big Hut Stricklin fans. Circuit City, baby.)
2nd most popular: #5
It’s a racer’s number, plain and simple. From Speed Racer to Penelope Pitstop to a host of NASCAR stars, 93,350 times a car has been assigned on Trading Paints with the #5.
Most popular: #1
Of course, it could only be #1 in P1. There are 95,389 Custom Number paints assigned as #1, and none of them belong to Smitty Werbenjägermanjensen.
Least popular Custom Numbers
Since we shared the top 10, it’s only fair to share the bottom 10.
These numbers are the least-frequently used as Custom Number paints (from 0-99, including numbers with leading zeroes). If you’re shopping around for a unique new number, this might be a great place to look.
10th least popular: #70 (7,015 paints)
9th least popular: #68 (6,677 paints)
8th least popular: #65 (6,127 paints)
7th least popular: #06 (6,123 paints)
6th least popular: #04 (5,842 paints)
5th least popular: #80 (5,340 paints)
4th least popular: #03 (5,143 paints)
3rd least popular: #59 (4,947 paints)
2nd least popular: #08 (4,271 paints)
…and the least popular custom number on Trading Paints: #05 (3,754 paints).
Number Builder inspo from the team
The Trading Paints team put together a few “starter projects” with Number Builder, our free web app for making your car number your very own.
