Trailer ID Numbers – Trailer Side (Set of 2)
Trailer ID Numbers – Trailer Side (Set of 2)
High-visibility vertical fleet number decals designed specifically for semi-trailers and box trailers. This product produces stacked, vertical numbers for trailer identification — no layout selection required.
This product is for numeric fleet or unit numbers only. No logos, words, or regulatory markings.
Each order includes a set of two matching decals, intended for placement on both sides of a trailer.
Orientation (Important)
Trailer numbers are produced for vertical installation, with digits stacked top-to-bottom (as shown in the product images). This orientation is standard for trailer identification and does not require any customization selection.
If you need horizontal numbers for truck doors, please select the Fleet Truck Number Decals product instead.
How Sizing Works
You are choosing the height of ONE digit, not the total height of the whole stack.
Digit Height = the height of each individual number (top to bottom).
Total stack height depends on how many digits you enter.
Example:
Choosing 4" digit height means each number is 4" tall.
A 3-digit number will be ~12–14" total height.
A 6-digit number will be ~24–28" total height.

Frequently Asked Questions
Collapsible content
Is this one decal or a pair?
This listing includes a set of 2 decals — one for the driver door and one for the passenger door.
What material are these made from?
We use Oracal® 651 professional-grade vinyl, the same material used by commercial sign shops. It’s rated 5–7 years outdoors and designed for vehicle use.
Will the decals hold up to weather, highway speeds, and washes?
Yes. The vinyl is UV-resistant, waterproof, and weather-safe, and holds up to sun, rain, and normal highway use.
We recommend waiting 72 hours after installation before washing.
Are these easy to install?
Yes. Each decal comes pre-spaced with transfer tape for a DIY install.
Clean the surface, apply pressure evenly, and peel the transfer tape slowly.
Can I see a proof before you cut it?
Yes. Select “Request Proof” at checkout if you’d like to review the layout before production.
What if I make a mistake entering my information?
Please double-check all spelling and numbers before checkout.
We cut exactly what is submitted. Returns are not accepted for custom items.
