Caterpillar Forklift Serial Number Lookup: Where Do I Find It?

Note: This page is for Caterpillar and Mitsubishi forklifts only. To find a serial number for a forklift of a different brand, click here for our other guides.The most direct way to find your Caterpillar forklift’s serial number is to check the forklift’s nameplate (also called a data tag). This helpful little label includes lots of various details about your lift–its model, its weight, its lifting capacity, and more. Most importantly, the nameplate also displays the forklift’s serial number. On a Caterpillar forklift, the nameplate looks like the image to the left and is often found near the dashboard, like in the image to the right:

Caterpillar is also associated with the Mitsubishi brand, so if you have a Mitsubishi forklift, the nameplate may look something like this:

Checking the nameplate is the quickest and easiest method of discerning the serial number of your forklift. But what if the nameplate wears down or has fallen off? You’re not out of luck just yet. Sometimes, a Caterpillar forklift’s serial number can be found physically stamped on its frame. Below is a list of different models of Caterpillar forklifts and some diagrams showing where their serial numbers can be found.

Models and serial numbers

In general, a Caterpillar forklift’s serial number is stamped on the chassis frame above the right-hand front wheel. For certain models that are represented by diagrams, see the highlighted portions of the figures below.
