By federal code, the VIN plate needs to be on the front half of the left side of the trailer in a place where it can be seen without having to move anything. Determine where, on the front half of the left side of your trailer, you will place the plate.
If the VIN plate already has holes, go to step three. If there are no holes in the VIN plate, use a clamp to firmly hold your VIM plant. Use a small pilot drill bit to drill a hole in each of the four corners. Using a pilot drill bit will minimize the damage to the reverse side of the plate. Depending on the size of the VIN plate, you may also wish to drill a hole in the middle of the VIN plate at the top and bottom.
Using the VIN plate's holes as a template, mark on the left front side of the trailer where to drill, with a pencil through each hole.
Hold the drill at a right angle to the trailer at one of the pencil points. Drill a starter hole for a screw. Repeat for each of the holes.
Change the bit on the drill to the screwdriver bit.
Screw the VIN plate onto the trailer.
