Truck Unit Number
Keep Your Fleet Compliant and Organized with Unit Number Stickers
Every commercial vehicle in your fleet plays a critical role — and needs to be clearly identified not just for your internal use, but also for DOT compliance and roadside inspections. These custom truck unit number decals are designed specifically to meet federal guidelines while giving your fleet a clean, unified look.
Why Unit Number Stickers Matter
The Federal Motor Carrier Safety Administration (FMCSA) recommends displaying unique unit numbers on each commercial motor vehicle. This helps:
- Law enforcement and DOT officers identify a vehicle quickly during inspections
- Dispatchers coordinate logistics across multiple trucks
- Maintenance teams assign service records by vehicle
- Insurance and safety audits verify fleet data easily
DOT-Compliant Sizing & Legibility
To ensure compliance, each unit number is:
- Printed in block letters/numbers
- Sized at a minimum of 2 inches in height
- Created using high-contrast colors (black, white, or others) for maximum visibility
These specifications are aligned with DOT standards for fleet marking and ensure the number is legible from the required viewing distance typically at least 50 feet under normal lighting conditions.
Made for the Road
Each decal is crafted from professional-grade vinyl that’s:
- UV resistant
- Weatherproof
- Scratch-resistant
- Built for long-term outdoor use
It applies easily to any clean, smooth surface including truck doors, hoods, or fenders, and will hold strong through heat, rain, snow, and washing cycles.
Installation is Easy
- Clean the surface thoroughly
- Peel and align the sticker
- Press down firmly and smooth with a squeegee or flat edge
- Done in minutes — no special tools required
Need to remove it later? With heat and a clean lift, these decals can be replaced without leaving adhesive residue behind.

Design Guidelines
Have a design file ready for print? We recommend that you review the following guidelines before placing your order.
Dimensions Required
Please select your product's width and height above to view the design guidelines and file setup specifications.
Understanding File Setup
Extend your background to fill the full "bleed area." This will make sure you do not end up with white edges when your product is cut.
This is where we aim to cut your final product size.
Keep all of the important elements of your design-text, logo, icons-inside this area. It's okay for backgrounds and images to run all the way to the bleed area.
What type of files will you accept?
We recommend vector-based .PDF design files. Most major design applications can generate a print-ready .PDF by using the Save As feature and selecting "Adobe PDF." If you are unable to obtain a .PDF file for your design, the best are those in .EPS or .AI (CS3 or higher) format with all text converted to outlines.
Recommended file types:
Vector-based .PDF, .PS, .PSD, or .EPS. Vector-based Adobe Illustrator .AI
Other accepted file types:
.PNG, .TIF, .BMP, .GIF, or .JPG
