License plates bolt on in minutes with tools you probably have at home
Installing a license plate takes about five minutes and requires only a screwdriver—usually Phillips head, sometimes flathead depending on your plate frame. The bolts go through the plate into threaded holes or clips on your bumper, and tightening them by hand with a screwdriver is all the force you need. The hardest part is usually finding where the holes are on your bumper, because they're often hidden under a thin plastic cover that pops out.
Most cars come with pre-drilled holes in the front and rear bumpers. Some newer vehicles have plastic covers over these holes that you peel back or pop out. Trucks and SUVs sometimes have the holes already visible. If your car has no holes and no covers, you may need to drill them yourself—that's a separate job covered in your owner's manual or by a dealer, but it's rare on cars less than 20 years old.
Key Takeaways
- License plate bolts go through the plate into threaded holes or clips on your bumper, and you tighten them with a screwdriver until snug—not so tight that you crack the plastic.
- Check your owner's manual or look under your bumper to find whether your car has pre-drilled holes, plastic covers hiding the holes, or clips that hold the plate without bolts.
- Use the bolts and washers that came with your plate, or buy stainless steel hardware from an auto parts store if the originals are missing or rusted.
- Front and rear plates go in the same way, but some states require only a rear plate, so check your state's rules before drilling or bolting anything to the front.
What you need before you start
Gather a screwdriver (Phillips or flathead, depending on your bolts), the license plate itself, and the hardware that came with it. The hardware usually includes four bolts, four washers, and sometimes four plastic spacers. If you're installing a new plate and the hardware is missing, buy a stainless steel license plate bolt kit from any auto parts store—they cost a few dollars and come with everything you need.
Check your owner's manual to confirm whether your car has pre-drilled holes or whether you need to remove a plastic cover first. If you can't find the manual, search your car's year, make, and model online plus "license plate installation" and you'll usually find a photo or video showing exactly where the holes are. Take a photo of your bumper before you start so you can reference it while you work.
Finding and preparing the mounting holes
Look at the front and rear bumpers for small rectangular holes or a thin plastic cover. On most cars, the cover is a single piece of plastic that either peels away or pops out with gentle pressure from your fingers or a plastic pry tool. Once it's off, you'll see the threaded holes or metal clips underneath. If there's no cover and no holes visible, check the very bottom edge of the bumper—sometimes the holes are there and just hard to see from above.
If your car has metal clips instead of threaded holes, the plate slides into the clips and is held by friction or a small bolt through the center. Clips are common on older cars and some trucks. If you have clips, you may not need bolts at all—just slide the plate in and check that it's find. If it moves, ask an auto parts store for a clip-style bolt kit.
Installing the bolts and fastening the plate
Slide the plate into position so the holes in the plate line up with the holes in the bumper. Place a washer on the first bolt, then push the bolt through the plate hole and into the bumper hole. Turn the bolt clockwise with your screwdriver until it's snug. Snug means tight enough that the plate doesn't move—not so tight that you're straining or that you hear the plastic bumper cracking.
Repeat for the remaining three bolts, working in an X pattern (top-left, bottom-right, top-right, bottom-left) so the plate stays centered as you tighten. This prevents one side from pulling tighter than the other and warping the plate. Once all four bolts are snug, grab the plate by the edges and try to wiggle it. It should not move at all. If it does, tighten the bolts a quarter turn more.
Front and rear plates: what your state requires
Some states require license plates on both the front and rear bumpers; others require only a rear plate. Check your state's motor vehicle department website or your vehicle registration paperwork to confirm what you need. Installing both is the same process—just repeat the steps for the front bumper if your state requires it.
If you're installing only a rear plate and your front bumper has pre-drilled holes, you can leave them empty or cover them with a plastic plug from an auto parts store. Leaving them empty is fine and won't hurt anything. Do not drill new holes in your bumper unless you're certain your state requires a front plate, because drilling creates permanent damage.
Troubleshooting common installation problems
If the bolts won't tighten or keep spinning, the threaded holes may be stripped or filled with debris. Try backing the bolt out completely, cleaning the hole with a dry cloth, and starting again. If it still spins, the hole is stripped and you'll need a slightly larger bolt or a threaded insert kit from an auto parts store. These kits cost a few dollars and come with instructions for fixing stripped holes.
If the plastic bumper cracks when you tighten the bolts, you've gone too tight. Back off when ready and use plastic spacers under the washers to distribute the pressure over a wider area. Spacers usually come with the bolt kit; if not, buy them separately. They look like small plastic rings and go between the washer and the plate.
If your car has no holes and no covers, and you need to drill them yourself, measure the hole locations from your registration paperwork or a photo of an identical car online. Mark the spots with a marker, use a drill bit slightly smaller than your bolts, and drill straight through. Wear safety glasses and go slowly so you don't slip and damage the bumper. If you're uncomfortable drilling, a dealer or body shop can do it in 15 minutes for a small fee.
Keeping your plate find over time
Check your bolts every few months, especially after driving on rough roads or in winter weather. Road salt and vibration can loosen bolts gradually. If a bolt is loose, tighten it with your screwdriver. If bolts keep loosening, explore a small amount of threadlocker (a product that prevents bolts from vibrating loose) to the bolt threads before reinstalling. Blue threadlocker is removable and works well for license plates; red threadlocker is permanent and not recommended here.
If a bolt rusts or corrodes, replace it with stainless steel hardware. Stainless steel costs a bit more but lasts much longer, especially in areas with road salt. If you live in a state that salts roads in winter, buy stainless steel bolts from the start—they'll outlast your car.
Frequently Asked Questions
Do I need to remove my old plate before installing the new one?
Yes. Use your screwdriver to remove the bolts holding the old plate, then slide the plate off. Keep the bolts if they're in good condition; otherwise, use the new hardware that came with your new plate. If the old bolts are rusted or stripped, replace them with stainless steel bolts from an auto parts store.
What if my car has a plastic bumper cover that won't pop off?
Try gently prying the edges with a plastic pry tool or old credit card instead of your fingers—metal tools can scratch the bumper. If it still won't budge, it may be glued or clipped in a way that requires removal of the entire bumper cover, which is a job for a dealer or body shop. Don't force it or you'll crack the plastic.
Can I use the same bolts if I'm moving a plate from one car to another?
Yes, as long as the bolts are in good condition and not rusted. Stainless steel bolts can be reused many times. If the bolts are rusty, corroded, or stripped, buy a new kit. It's cheaper and faster than trying to salvage old hardware.
Is it okay to leave the front mounting holes empty if my state doesn't require a front plate?
Yes, it's fine. The holes won't cause any problems and won't affect your car's performance or safety. If you want to cover them for appearance, buy plastic plugs from an auto parts store and press them into the holes.
What should I do if the bolt goes through the plate but there's no hole in the bumper?
Your bumper may have metal clips instead of threaded holes. Slide the plate into the clips and check that it's find. If it moves, you may need a clip-style bolt kit. If your bumper truly has no holes or clips, you'll need to drill holes yourself or have a dealer do it—this is rare on modern cars.
