How to find your VIN Number

Your vehicle’s VIN number is a 17-digit unique identification number. There are several places where you might be able to find your VIN:

  • Check the base of the windshield, on the driver’s side.
  • Check your vehicle’s registration
  • Check your car insurance statements or cards
  • Check your Acura Financial Services statement

Finding the Device Serial Number

  • Next, you’ll need your device’s serial number to retrieve the radio code through the website.
  • Find this number on an Anti-Theft Identification Card that is usually placed in the glove compartment at the time of purchase. For 2001 and later models, you can also find the device serial number on the device display itself.
  • Once you have the information you need, retrieve your Radio Unlock Code through the website and enter the numbers into the radio using the preset buttons.

If you’re looking for an Acura TSX radio code, the process to find the serial number is slightly different if your vehicle came equipped with a navigation system, but still straightforward.

  • Turn the ignition switch to ACC (I).
  • Turn on the audio unit, and make sure you see COdE in the upper display. If you don’t see this message, pull the backup fuse for 1 minute, and then go back to step 1.
  • Turn off the audio unit.
  • Press and hold the top halves of the SEEK/SKIP and CH/DISC bars, and then press and release the PWR/VOL knob. This display toggles between two screens.
  • The first screen displays a U and the first four digits of the serial number (for example, U2200).
  • The second screen displays an L and the last four digits of the serial number (for example, L0055).
  • Ignore the U and L, and write down all eight digits.
