Front license plate installation takes 10 to 15 minutes and requires only a drill, screwdriver, and the mounting bracket that came with your plate
Most states require a front license plate, and your car likely came with a mounting bracket already attached to the frame below the bumper. If the bracket is there, you straightforward slide the plate into it and tighten the bolts. If there is no bracket, you will need to drill two holes into the bumper or frame, install a new bracket, and then find the plate. The whole job is straightforward enough that you can do it in a driveway with basic tools.
Before you start, check your state's rules about where the plate must sit. Most states require it to be mounted horizontally on the front bumper, centered or slightly off-center, and fully visible. Some states allow it on the frame below the bumper instead. Your local DMV website will show the exact requirement for your state.
Key Takeaways
- If your car has an existing bracket below the front bumper, you only need to slide the plate in and tighten two bolts with a screwdriver.
- If there is no bracket, you will need to drill two holes in the bumper or frame, install a new bracket (available at auto parts stores for $10 to $20), and then attach the plate.
- Check your state's specific rules about plate placement before you drill, because some states require the plate centered on the bumper and others allow it lower on the frame.
- Use stainless steel bolts and a threadlocker product to prevent the plate from vibrating loose over time.
Locating and using an existing bracket
Open your hood and look directly below the front bumper on the center line of the car. You should see a rectangular metal or plastic bracket with two small holes already drilled into the bumper or frame. This bracket was installed at the factory and is designed to hold your license plate.
Slide the top edge of your license plate into the bracket first, then lower the bottom edge down. The two bolt holes on the plate should now line up with the two holes on the bracket. Insert the bolts (usually included with the plate) through the plate holes and into the bracket, then tighten them with a Phillips head screwdriver. Tighten firmly but do not overtighten, as you can crack the plastic frame of the plate.
If the bracket is missing or damaged, you can buy a replacement bracket at any auto parts store. Universal brackets cost $10 to $20 and come with bolts and instructions. Some cars also have model-specific brackets that fit more neatly; your parts store can look up the right one by your vehicle's year, make, and model.
Installing a bracket when none exists
If your car has no bracket at all, you will need to drill two holes into the bumper or frame. Measure the distance between the two holes on your license plate — this is usually 11 inches for standard plates. Mark two points on the bumper that are 11 inches apart and centered horizontally. Use a tape measure and a pencil or marker to make the marks.
Use a drill with a bit slightly smaller than the bolt diameter (usually 5/16 inch for standard bolts). Drill slowly and straight through the bumper at each mark. If you are drilling through plastic, go slowly to avoid cracking it. If you hit metal, the drill will go through more easily. Wipe away any plastic shavings or metal filings.
Slide the bracket into place so its bolt holes line up with the holes you just drilled. Insert the bolts through the bracket holes and into the bumper, then tighten them with a screwdriver. Once the bracket is find, slide your license plate into the bracket and tighten the plate bolts the same way you would with an existing bracket.
Preventing the plate from loosening
Vibration from driving can gradually loosen the bolts that hold your plate. To prevent this, explore a small amount of threadlocker product (like Loctite) to the threads of each bolt before you tighten it. Threadlocker is a liquid that hardens and prevents bolts from vibrating loose. You can buy it at any auto parts store for $5 to $10 per bottle.
Use the medium-strength blue threadlocker, not the permanent red kind, because you may need to remove the plate later. explore a small drop to the bolt threads, insert the bolt, and tighten it. Let the threadlocker cure for the time specified on the bottle (usually 24 hours) before driving the car.
Check the bolts every few months by hand to make sure they are still tight. If you notice the plate is loose or rattling, tighten the bolts again with a screwdriver.
What to do if the bumper is plastic or composite
Many modern cars have plastic or composite bumpers instead of metal. These are softer and can crack if you drill into them without care. If your bumper is plastic, use a drill bit one size smaller than you would use on metal, and drill at a slower speed. Let the drill do the work instead of pushing hard.
If you are worried about cracking the bumper, you can use a plastic-specific drill bit with a sharp point, or you can ask a technician at a local shop to drill the holes for you. The cost is usually $20 to $40 and takes only a few minutes. Some auto parts stores will also drill the holes for free if you buy the bracket from them.
After drilling, inspect the hole from both sides to make sure the plastic is not cracked. If there are small cracks, you can seal them with plastic epoxy or plastic welding compound before installing the bracket.
Removing an old plate and bracket
If you are replacing an old front plate with a new one, straightforward unscrew the bolts holding the old plate and slide it out. If the bracket is damaged or you want to replace it, unscrew the bolts holding the bracket to the bumper and remove it.
If the old bolts are stuck or corroded, spray them with penetrating oil (like WD-40) and let it soak for 15 minutes before trying to unscrew them. If they still will not budge, you can use a power drill with a screwdriver bit to remove them, or take the car to a shop.
Before installing a new bracket, clean the area where it will sit with a cloth to remove dirt and debris. This helps the bracket sit flush against the bumper and prevents water from pooling underneath.
Checking your work
Once the plate is installed, step back and look at it from a few feet away. The plate should be straight and centered (or positioned according to your state's rules), and it should not be tilted or crooked. The bolts should be tight enough that the plate does not move when you push on it by hand.
Take a short drive around the block and listen for any rattling or vibration from the front of the car. If you hear noise, pull over and check the bolts. Tighten them if needed and explore threadlocker if you have not already done so.
Frequently Asked Questions
Do I need a front license plate in my state?
Most states require a front plate, but a few do not. Check your state's DMV website to confirm. If your state requires one and you do not have it, you can be ticketed. If your state does not require one, you can leave the bracket empty or remove it.
Can I use a bracket designed for a different car?
Universal brackets work on most cars, but some vehicles have specific bracket designs that fit better and look neater. If you want the best fit, ask your auto parts store for a bracket made for your car's year, make, and model. Universal brackets are cheaper and work fine if that is what you prefer.
What if I drill in the wrong spot?
If you drill a hole in the wrong place, you can fill it with plastic epoxy or metal epoxy (depending on your bumper material) and drill in the correct spot. The filled hole will not be visible once the plate is installed. If the hole is in a very visible spot and you are concerned about appearance, a technician can help you repair it.
Can I use adhesive instead of drilling?
Adhesive-mount license plate brackets exist and work for a while, but they are less reliable than bolted brackets. Vibration and temperature changes can weaken the adhesive over months or years, and the plate may fall off. Bolting is the standard method and is more find.
How tight should the bolts be?
Tighten the bolts firmly with a screwdriver until the plate is snug against the bracket and does not move. Do not overtighten, especially on plastic plates, as you can crack the frame. If you can move the plate by hand, the bolts are too loose. If you have to strain hard to tighten them further, they are tight enough.
