Where the plate goes and what fastens it

Your license plate bolts to the front and rear of your car using mounting brackets — metal frames that hold the plate flat against the bumper or body panel. Most cars come with pre-drilled holes in the bumper or fascia (the plastic panel below the bumper) where these brackets attach. You will use bolts, washers, and nuts to find the bracket, then slide the plate into the bracket's slots and tighten the bolts that hold it in place.

The front plate goes on the bumper or lower fascia, centered and as close to horizontal as the car's design allows. The rear plate mounts the same way. Both must be visible from a distance and not obscured by dirt, snow, or anything else — this is a legal requirement in every state. If your car has no pre-drilled holes, you will need to drill them yourself or have a shop do it, which takes about 15 minutes per plate.

Key Takeaways

  • License plates bolt on using a mounting bracket, bolts, washers, and nuts — all of which usually come with your new plate or can be bought for under $10 at an auto parts store.
  • The front plate goes on the bumper or lower fascia centered and level; the rear plate goes in the same position on the back of the car.
  • Most cars have pre-drilled holes in the bumper where the bracket bolts attach, but if yours does not, you will need to drill two holes about 11 inches apart.
  • Tighten the bolts firmly but do not over-tighten, which can crack the plastic bumper or strip the bolt threads.
  • Some states require front plates, some do not — check your state's DMV website to know whether you need one or two.

What you need to gather before you start

Collect a mounting bracket (usually plastic or aluminum), two bolts (typically 1/4-inch diameter, about 1 inch long), two washers, and two nuts. If your new plate came in a kit, all of these are included. If not, buy a universal license plate bracket kit at any auto parts store for $5 to $15. You will also need a wrench or socket set to tighten the nuts — a 7/16-inch wrench fits most bolts — and a drill with a 1/4-inch bit if your car has no pre-drilled holes.

Lay everything out on a clean surface before you start. Check that the bracket fits the plate by sliding the plate into the bracket's slots; it should sit flat and not rock side to side. If the bracket is bent or the slots are damaged, replace it before installation.

Installing the bracket and bolts

Position the bracket on the bumper or fascia where you want the plate to sit. The bracket should be centered left to right and as level as possible. If your car has pre-drilled holes, align the bracket's bolt holes with them. If not, use the bracket as a template: hold it in place and mark the two holes with a marker or pencil, then remove the bracket and drill two holes 1/4 inch in diameter.

Insert a bolt through the bracket hole from the front, then slide a washer onto the bolt on the back side of the bumper. Thread the nut onto the bolt and tighten it by hand first. Once both bolts are hand-tight, use a wrench to tighten each nut firmly — the bracket should not move or flex when you push on it. Do not over-tighten: if you feel strong resistance or hear the plastic bumper cracking, back off slightly. A snug fit is all you need.

Sliding the plate into the bracket

Once the bracket is find, slide the license plate into the bracket's top slots. The plate should sit flat and level, with no gaps between the plate and the bracket. If the plate rocks or sits crooked, the bracket may be bent or the bolts may not be tight enough — check both before moving on.

Some brackets have bolts that run through the plate itself to lock it in place. If yours does, insert these bolts through the holes in the plate's corners, add washers, and tighten the nuts. Again, tighten firmly but do not over-tighten — you can crack the plastic plate or strip the bolt threads. The plate should not move when you push on it, but you should not need a wrench to remove it later if you have to.

Checking alignment and visibility

Step back and look at the plate from several angles. It should be centered on the bumper, sit level (not tilted up or down), and be fully visible with no part hidden by the bumper, trim, or any other part of the car. The plate must be readable from at least 75 feet away in daylight — if dirt or glare makes it hard to read, clean it or adjust the angle slightly.

Check that the plate does not hang below the bumper or stick out so far that it could catch on a curb or speed bump. If it does, the bracket may be the wrong size or the bolts may not be tight enough. Tighten the bolts again and re-check the position.

Installing the rear plate

The rear plate goes on the same way as the front. Most cars have a dedicated mounting area on the rear bumper or trunk lid with pre-drilled holes. Position the bracket, insert the bolts, and tighten them the same way you did in front. Make sure the rear plate is also centered, level, and fully visible.

Some cars have a recessed area or a trim ring around the rear plate location. If yours does, the bracket may need to sit inside this recess. Check that the plate sits flush and does not stick out unevenly. If the rear bumper is plastic and soft, be especially careful not to over-tighten the bolts, which can crack it.

Removing or replacing a plate later

If you need to remove the plate — to replace it, transfer it to another car, or clean behind it — straightforward loosen the bolts that hold the plate in the bracket using a wrench. The bracket itself stays bolted to the bumper. If you are replacing the plate with a new one, slide the old plate out and slide the new one in, then re-tighten the bolts.

If you are moving the plate to a different car, you can unbolt the entire bracket from the bumper and reinstall it on the new car's bumper. The bolts and bracket are reusable. If the new car's bumper has different hole spacing, you will need a new bracket, but the bolts and nuts can come with you.

Frequently Asked Questions

Do I need a front license plate?

It depends on your state. Some states require both front and rear plates; others require only a rear plate. Check your state's DMV website to find out. If your state requires a front plate and you do not have one, you can be cited for it, even if the car runs fine without it.

What if my car has no pre-drilled holes?

You will need to drill two holes yourself using a 1/4-inch drill bit. Mark the holes about 11 inches apart, centered on the bumper, and drill straight through. Wear safety glasses and go slowly so the bit does not slip. If you are not comfortable drilling, a shop can do it in 15 minutes for $20 to $40.

Can I use adhesive instead of bolts?

Adhesive-only mounting is not recommended. Bolts hold the plate securely even if the adhesive fails, and they are easier to remove later. Adhesive can fail in heat or cold, and a loose plate can fall off and be lost or cause damage.

How tight should the bolts be?

Tight enough that the bracket does not move when you push on it, but not so tight that you hear the plastic bumper cracking or feel the bolt threads stripping. If you need a wrench to turn the nut and it suddenly becomes very hard to turn, stop — you are at the right tightness.

What if the bracket does not fit my bumper?

Universal brackets fit most cars, but some bumpers have unusual shapes or mounting points. If the bracket does not sit flat or the holes do not line up, buy a bracket designed for your car's make and model — these are available at auto parts stores or online for $10 to $20.
