Finding my RPO code by VIN

Let me start by defining what VIN is. VIN, known as a vehicle identification number, is a 17-digit character manufacturer assigns to every car upon production. And it contains information about your car. This includes manufacturer, production year, model, production plant, engine types, vehicle history, etc. You can find your VIN in several locations depending on your car.

They can be on the driver’s side dashboard, engine block, car window, beneath the spare tires, etc. Cars like GM also have them on their vehicle title, insurance card, or vehicle registration. So whatever car information you need, your VIN can provide, including your RPO codes. So here is how to find RPO code with VIN number.

You can visit or call your dealer requesting your RPO codes. But if you’re calling, ensure you have your VIN by your side so you can call it for them when needed. They should be able to help you with this code. Importantly, you may need to specify which RPO code you need, especially if you’re calling.

Every part in your vehicle has a designated RPO code. Each RPO code is basically a three-digit alphanumeric number representing specific parts of your vehicle. And there are over 77 of these codes. So stating which code you need will make the process much easier.

For example, when I need to change my shocks, I specify that I need the shock’s RPO code. Thus, I ensure I get only the correct shocks. This even removes the burden of decoding these codes, especially if you don’t know how to read RPO codes.
