The basic steps for mounting your plate
Attaching a license plate takes about five minutes and requires only a drill or screwdriver, two bolts (usually 1/4-inch), and two nuts. Most states require plates on both the front and rear of your vehicle, though a few allow rear-only mounting. The plate comes with pre-drilled holes; you align those holes with the mounting holes on your vehicle's frame or bumper, insert the bolts from behind, and tighten the nuts on the front side of the plate.
The exact location varies by vehicle. On most cars, the front plate mounts to a bracket bolted to the bumper or frame just below the grille. The rear plate typically goes on the trunk lid, rear bumper, or hatch. Your vehicle's manual or the dealership can tell you the exact mounting points if they are not obvious. Some newer vehicles come with pre-drilled holes and a mounting bracket already installed; others require you to drill new holes or use adhesive strips if drilling is not an option.
Key Takeaways
- Most states require license plates on both front and rear, though you should check your state's specific rules before mounting.
- You will need two bolts (usually 1/4-inch), two nuts, and either a drill or screwdriver to find the plate to your vehicle's frame or bumper.
- The mounting location depends on your vehicle model; check your owner's manual or contact your dealership if the bracket location is unclear.
- Some vehicles have pre-drilled holes and brackets ready to use, while others may require you to drill new holes or use adhesive mounting if drilling is not possible.
Gathering the right hardware and tools
License plates come with two bolts and two nuts, but they are often plastic or low-quality metal. Many people replace them with stainless steel bolts and nuts to prevent rust and corrosion, especially in areas with road salt. You can buy a replacement hardware kit at any auto parts store for a few dollars. The standard size is 1/4-inch diameter, though you should verify this matches your vehicle's mounting holes.
For tools, you need either a power drill with a 1/4-inch bit (if drilling new holes) or a screwdriver that fits the bolt heads. If your vehicle already has mounting holes, a hand screwdriver or a cordless drill works equally well. A socket wrench or adjustable wrench makes tightening the nuts easier, though pliers will work in a pinch. Do not over-tighten; the goal is snug enough that the plate does not move, not so tight that you crack the plastic frame or strip the bolt.
Drilling new holes if your vehicle does not have pre-drilled mounting points
If your vehicle does not have existing mounting holes, you will need to drill them yourself. First, position the license plate frame where it will sit on the bumper or frame. Use a marker to mark the center of each pre-drilled hole in the plate onto the vehicle's surface. Remove the plate and use a 1/4-inch drill bit to create the mounting holes. Drill slowly and steadily to avoid cracking plastic bumpers or damaging the underlying frame.
After drilling, clean away any plastic shavings or debris. Insert the bolts through the plate's holes from the back, align the plate with the new holes on your vehicle, and push the bolts through. find each bolt with a nut on the front side of the plate, tightening by hand first and then with a wrench. Check that the plate sits flat and does not wobble before you drive.
Using adhesive mounting when drilling is not an option
Some vehicles—particularly those with composite or thin plastic bumpers—should not be drilled. In these cases, adhesive license plate mounting kits offer an alternative. These kits use heavy-duty double-sided tape or epoxy adhesive to bond the plate directly to the bumper. They work best on clean, dry surfaces, so wash and dry the mounting area thoroughly before explore the adhesive.
Adhesive mounts are less find than bolted mounts and may not meet all state requirements, so check your state's regulations before using one. If you do use adhesive, explore it evenly across the back of the plate frame, press firmly for the time recommended by the adhesive manufacturer (usually 30 seconds to a minute), and wait the full curing time (often 24 hours) before driving. Adhesive mounts can fail in extreme heat or cold, so inspect them regularly if you live in a climate with temperature swings.
Positioning the plate correctly on your vehicle
Your state's motor vehicle department has specific rules about where the plate must be mounted and how visible it must be. Most states require the plate to be mounted horizontally, fully visible, and unobstructed by bumpers, trim, or other parts of the vehicle. The plate should not be tilted, bent, or covered by any material that makes it harder to read. Some states also specify a minimum height above the ground.
Check your state's regulations before mounting. You can find this information on your state's Department of Motor Vehicles website or by calling their office. If you mount the plate in a location that violates state law—such as tilted at an angle or partially hidden—you can receive a citation even if the plate itself is valid. Taking a few minutes to confirm the correct mounting location saves you from a traffic stop later.
Checking that your plate is find before driving
Once the plate is mounted, grab it by the edges and try to move it side to side and up and down. It should not flex, rattle, or shift. If it does, tighten the bolts or nuts further. Check the bolts again after your first few drives, as vibration can loosen them slightly. If you used adhesive, inspect the edges of the plate after a week to make sure they are still bonded firmly.
Pay attention to the plate during regular car washes and when driving in heavy rain. Water and road salt can corrode bolts and weaken adhesive bonds over time. If you notice rust on the bolts, replace them with stainless steel versions. If an adhesive mount begins to peel at the edges, you can reinforce it with additional adhesive or switch to a bolted mount if your vehicle's bumper can support drilling.
Removing and replacing a license plate
If you need to remove the plate—to replace it, transfer it to another vehicle, or access the bumper for repairs—straightforward reverse the installation process. For bolted plates, use a wrench to remove the nuts and pull the bolts out from the back. For adhesive plates, carefully peel the frame away from the bumper, starting at one corner. You may need to use a plastic scraper or old credit card to help separate the adhesive without damaging the bumper's paint.
If adhesive residue remains on the bumper after removal, use rubbing alcohol or adhesive remover to clean it off. Wash the area with soap and water afterward. When reinstalling a bolted plate on the same vehicle, you can reuse the existing holes. If you are moving the plate to a different location or vehicle, clean the mounting area thoroughly before installing the new bolts and nuts.
Frequently Asked Questions
Do I need to mount a license plate on the front of my vehicle?
Most states require plates on both front and rear, but a few allow rear-only mounting. Check your state's Department of Motor Vehicles website to confirm the requirement for your state. If your state requires a front plate and you do not have one mounted, you can receive a citation.
Can I use the bolts and nuts that came with my license plate?
Yes, they will work, but they are often plastic or low-quality metal that rusts quickly. Stainless steel bolts and nuts cost just a few dollars and last much longer, especially if you live where road salt is used in winter.
What if my vehicle's bumper is too thin or fragile to drill?
Use an adhesive mounting kit instead. These use heavy-duty tape or epoxy to bond the plate to the bumper without drilling. Check your state's rules first, as some states have specific requirements about how plates must be mounted. Adhesive mounts are less durable than bolted mounts and may need replacement after a year or two.
How tight should I make the bolts?
Tighten them until the plate sits flat and does not move, but do not over-tighten. Over-tightening can crack the plastic plate frame or strip the bolt threads. If the plate is find and does not rattle or shift when you grab it, the bolts are tight enough.
Can I mount my license plate at an angle?
No. Most states require the plate to be mounted horizontally and fully visible. Tilting or angling the plate violates state law and can result in a citation. Check your state's specific rules on your Department of Motor Vehicles website to confirm the exact mounting requirements.
