Custom dealer license plate inserts are one of the simplest ways for automotive dealerships to extend their branding beyond signs, websites, and digital advertising.
Every vehicle sitting on the lot, being driven during a test drive, moving between dealership locations, or traveling through the community can become another opportunity for people to see and recognize your dealership.
The challenge is choosing the right insert for the job.
Dealer plate inserts are available in different material thicknesses, print styles, and designs. Some are best suited for temporary inventory use, while others are designed to stay on vehicles for long term dealership advertising.
In this guide, we will cover how dealerships use personalized license plate inserts for automotive branding, the differences between 18 mil, 23 mil, 35 mil, and 55 mil polyethylene inserts, when one color or full color printing makes sense, and how to create a design people can actually recognize while a vehicle is moving.
What Are the Best Personalized License Plate Inserts for Automotive Branding?
There is no single best license plate insert for every dealership.
The right choice depends primarily on how long the insert will remain on the vehicle and the type of presentation you want.
For short term vehicle merchandising and temporary dealership displays, 18 mil or 23 mil polyethylene inserts are generally the most practical options.
For dealerships that want their branding to remain on vehicles for a longer period, 35 mil polyethylene offers the best overall balance of durability, flexibility, appearance, and cost for most dealerships.
For luxury dealerships and other businesses looking for a heavier premium presentation, 55 mil polyethylene provides the most substantial option.
The design matters just as much as the material.
In many cases, a simple plate insert with a bold background and a large dealership logo can be more effective than a heavily designed insert containing a website, phone number, address, slogan, and multiple graphics.
The reason is simple.
Cars move.
Your branding has to be recognizable quickly.
Why Dealerships Use Custom License Plate Inserts
A dealership may spend significant money creating awareness through Google Ads, social media, third party automotive marketplaces, television, direct mail, and other advertising channels.
Custom dealer license plate inserts offer something different.
They put the dealership's brand directly onto the vehicles themselves.
That creates opportunities for dealership exposure while vehicles are:
- Parked throughout the dealership lot
- Positioned near high traffic roads
- Taken on customer test drives
- Moved between dealership locations
- Displayed at automotive events
- Parked throughout the local community
- Driven by customers after the sale where permitted
For dealerships that sell hundreds or thousands of vehicles each year, that can create a significant amount of recurring local brand exposure.
A customer does not necessarily need to read your phone number or remember your website.
Sometimes the value is simply seeing the same dealership logo repeatedly until the brand becomes familiar.
Dealer Plate Inserts Help Create a More Branded Car Lot
Before thinking about advertising outside the dealership, there is also value in how the vehicles look while they are still in inventory.
A coordinated plate insert program gives vehicles throughout the dealership a more consistent appearance.
Instead of seeing empty front plate areas, random mounting hardware, or different plate designs throughout the lot, customers see the same dealership branding repeated across the inventory.
That repetition reinforces the dealership name while helping the lot look more organized and professionally merchandised.
This can be especially noticeable on dealerships positioned along major roads where hundreds or thousands of drivers may pass the inventory every day.
Why Front and Rear License Plate States Can Still Use Dealer Inserts
Dealerships located in states that ultimately require both front and rear permanent license plates may assume there is little reason to invest in custom inserts.
There are still several potential applications.
Vehicles sitting in inventory do not necessarily have their permanent customer plates installed yet.
That creates an opportunity for dealership branding while vehicles are displayed on the lot or being used for test drives, subject to applicable state rules.
When a customer takes a vehicle on a test drive, dealership branding can leave the lot with the vehicle.
That means the car is creating impressions outside the dealership before it is ever sold.
Dealers should always follow their state's requirements regarding legal registration plates, temporary permits, and display placement. A custom dealership insert should not be considered a substitute for a state required registration plate or temporary permit unless the dealership has confirmed that the application complies with applicable state rules.
Rear Plate States Create a Long Term Front Branding Opportunity
The opportunity becomes even more interesting in states where standard passenger vehicles only require a rear license plate.
The unused front plate mounting area can provide dealerships with an additional branding location.
A custom dealership insert installed on the front of the vehicle can remain visible even after the customer's permanent rear license plate has been installed.
At that point, the insert becomes more than an inventory merchandising product.
It becomes mobile dealership advertising.
Vehicles may be seen at:
- Grocery stores
- Offices
- Restaurants
- Schools
- Sporting events
- Shopping centers
- Neighborhoods
- Highways and local roads
When enough customers drive vehicles carrying the same dealership branding, the effect becomes cumulative.
People begin recognizing the dealership without consciously trying to remember it. The additional benefit is each vehicle is social proof to potential customers as they recognize that others in their community have trusted the dealership enough to spend their hard earned money there.
Branding During the Temporary Registration Period
There is also a transition period between the vehicle sale and permanent registration.
The exact registration process varies by state.
States such as Georgia, Michigan, and South Carolina have their own specific temporary registration or temporary plate requirements. Dealerships should always comply with their state's current requirements and should never treat a decorative dealership insert as a replacement for a legally required temporary registration.
However, when dealership branding can legally be incorporated alongside the required temporary registration or used elsewhere in the plate area, this period can provide another branding opportunity.
The larger strategic point is to think about dealership branding throughout the entire vehicle lifecycle.
That includes:
Inventory.
Test drives.
The sale.
Temporary registration.
And, where possible, continued dealership branding after the customer's permanent plate is installed.
Keep Dealer Plate Insert Designs Simple
One of the easiest mistakes to make with a custom dealer plate insert is trying to fit too much information into a 12 inch by 6 inch space.
A plate insert is not a brochure.
It is not even really a business card.
People often see the insert while the vehicle is moving or while passing it from a distance.
That means the most important question is not:
How much information can we fit on the insert?
A better question is:
What do we want someone to recognize in two or three seconds?
Usually, the answer is the dealership name or logo.
A very effective design may be nothing more than:
- A vibrant background color
- A large dealership logo
- Strong contrast
- Plenty of open space
That simplicity can make the branding much easier to recognize.
Pair a Simple Plate Insert With a Custom License Plate Frame
One way to keep the plate insert clean is to let the license plate frame provide some of the supporting information.
For example:
Plate insert: Large dealership logo on a bold background
License plate frame: Dealership name and city
This allows each product to serve a different purpose.
The insert attracts attention.
The frame provides additional brand identification.
A dealership could also put the dealership name on the insert and use the frame for a website, location, or short slogan.
There is nothing wrong with putting additional information directly on the plate insert.
The point is to avoid sacrificing recognition just to fill every available inch of space.
A Real Example of Simple Dealership Branding Working
After US Auto Supplies moved to Oregon, there was one local dealership whose vehicles kept standing out.
We do not supply that dealership and had no previous relationship with them.
But their plate branding was simple and consistent enough that we kept noticing the dealership's vehicles around the area.
Eventually, it became one of the local dealerships we could recognize by name simply because we had seen the branding repeatedly.
That is exactly what dealership vehicle branding is supposed to accomplish.
Someone does not need to stop and study the advertisement.
They simply need to recognize the brand the next time they encounter it.
One Color vs. Full Color Dealer License Plate Inserts
Another important decision is whether to choose a one color design or full color printing.
More colors do not automatically make a better plate insert.
The best choice depends on the dealership's branding.
When One Color Makes Sense
One color license plate inserts work particularly well for dealerships with straightforward branding.
For example:
- Black logo on white
- Blue dealership name on white
- Red logo on a contrasting background
- One color logo paired with a custom plate frame
One color printing can produce a very clean, traditional dealership appearance.
It can also be a more economical option when purchasing larger quantities.
If your dealership already has a recognizable logo or wordmark, one color may be all you need.
When Full Color Makes Sense
Full color printing becomes valuable when the dealership's identity depends on multiple colors or more detailed artwork.
Full color inserts can support:
- Multicolor dealership logos
- Corporate branding colors
- Gradients
- Detailed graphics
- Promotional designs
- More visually complex artwork
Full color digital printing provides much more creative flexibility.
But the same design principle still applies.
Do not make the design complicated just because full color printing makes it possible.
Bold, simple artwork is often easier to recognize from another vehicle.
What Thickness Should a Dealer License Plate Insert Be?
US Auto Supplies offers custom polyethylene dealer license plate inserts in four primary thicknesses:
18 mil
23 mil
35 mil
55 mil
All four serve slightly different applications.
18 Mil Polyethylene License Plate Inserts
Best for: Economical temporary dealership branding
18 mil polyethylene is a lightweight and economical option for temporary vehicle displays and shorter term applications.
It works well for dealerships that frequently install and remove plate inserts or primarily want branding on inventory vehicles before the permanent plate is installed.
Typical applications include:
- Dealership inventory
- Temporary display
- Short term merchandising
- Vehicles where inserts will be removed relatively quickly
Our full color 18 mil inserts are digitally printed and receive a complimentary UV clearcoat to help protect the artwork during their intended service life.
If the insert is primarily being used while the vehicle is sitting on the lot, there may be little reason to purchase a substantially heavier material.
23 Mil Polyethylene License Plate Inserts
Best for: More durable temporary and medium term applications
23 mil polyethylene provides additional durability without moving all the way into a heavier long term insert.
This option can make sense for dealerships that want something more substantial than an 18 mil insert while still keeping the product flexible and cost effective.
The polyethylene material also performs well through changing temperatures and cold weather.
Typical applications include:
- Longer inventory cycles
- Medium term dealership displays
- Colder climates
- Dealerships wanting additional durability without moving to 35 mil
For some dealers, 23 mil provides an excellent middle ground.
35 Mil Polyethylene License Plate Inserts
Best for: Long term dealership branding
35 mil polyethylene is our most popular long term dealership plate insert.
It provides a stronger, more substantial construction while maintaining the flexibility and weather resistance that make polyethylene well suited to automotive applications.
For most dealerships that want a plate insert capable of remaining on vehicles for extended periods, 35 mil is the option we would recommend first.
It offers a strong balance between:
- Durability
- Weather resistance
- Flexibility
- Professional presentation
- Cost
It also performs well across a wide range of climates and helps reduce the cracking around mounting holes that can occur with more rigid plastic materials.
If your objective is long term dealership advertising rather than temporary inventory merchandising, 35 mil is usually the best place to start.
55 Mil Polyethylene License Plate Inserts
Best for: Premium and heavy duty dealership presentation
55 mil polyethylene is the premium option in our plate insert lineup.
The heavier material provides greater rigidity and a noticeably more substantial feel.
It is particularly popular with businesses where presentation matters as much as basic durability.
Common applications include:
- Luxury automotive dealerships
- Powersports dealerships
- Motorcycle dealerships
- RV dealerships
- Specialty vehicle retailers
- Premium dealer groups
The added rigidity also makes 55 mil inserts well suited for applications where the insert may be displayed without a traditional license plate frame.
If the dealership wants the plate insert itself to feel like a premium branded accessory, 55 mil is the strongest choice.
18 Mil vs. 23 Mil vs. 35 Mil vs. 55 Mil Dealer Plate Inserts
The easiest way to choose a custom dealer license plate insert is to think about how long the insert needs to remain on the vehicle and the type of presentation you want.
| Thickness | Best For | Durability Level | Recommended Use |
|---|---|---|---|
| 18 Mil | Economical temporary branding | Light Duty | Short term vehicle displays, dealership inventory, and applications where inserts are installed and removed frequently |
| 23 Mil | More durable temporary or medium term use | Medium Duty | Longer inventory cycles, changing weather conditions, and dealerships wanting more durability without moving to a heavy long term insert |
| 35 Mil | Most long term dealership branding | Heavy Duty | Year round outdoor use, ongoing dealership advertising, and vehicles where the insert may remain installed for extended periods |
| 55 Mil | Premium dealership presentation | Premium Heavy Duty | Luxury dealerships, powersports dealers, RV dealers, specialty vehicles, and applications where additional rigidity and thickness are preferred |
For most dealerships looking for long term automotive branding, 35 mil polyethylene offers the best overall balance of durability, flexibility, appearance, and cost.
The thickest insert is not automatically the best choice. An 18 mil or 23 mil insert may make more sense if the plate is only being used temporarily, while 55 mil is better suited to situations where a more substantial premium presentation is part of the goal.
Why Polyethylene Works Well for Dealer Plate Inserts
Polyethylene is particularly useful for automotive dealership applications because it combines flexibility with outdoor durability.
It performs well through changing weather conditions and remains flexible in colder temperatures.
The bright white material also helps dealership artwork maintain a clean appearance through outdoor exposure.
All of our polyethylene inserts include a complimentary UV clearcoat to help protect the printed artwork.
Depending on the specific product selected, custom inserts are available with standard 5/16 inch round mounting holes, with oval mounting holes available upon request.
The standard insert size is 12 inches by 6 inches, allowing them to work with common dealership license plate frames.
How to Design a Better Dealer License Plate Insert
When creating your artwork, start with the most important piece of information.
For most dealerships, that is the logo or dealership name.
Then decide whether anything else actually needs to be on the insert.
A useful design hierarchy might be:
- Dealership logo
- Dealership name
- Short slogan or location
- Website or other secondary information
Do not feel obligated to use all four.
If the logo alone provides strong brand recognition, let the logo breathe.
The goal should be a plate that looks good on the vehicle from several feet away, not just artwork that looks impressive when zoomed in on a computer.

The same license plate frame.
Repeated across hundreds of vehicles.
That consistency is what turns a relatively small dealership accessory into a recognizable piece of local advertising.
