How to find your Subaru Impreza radio serial number

Where it is

On the label

  1. Take the radio out.
  2. Find the barcode label (use the bottom one if there are two).
  3. Type in its last 4 numbers.

Photograph the label rather than copying it by hand — 0 and O, 1 and I are easy to mix up.

RADIOPush both keys in until they click, then pull the radio forward

It comes out with a pair of radio removal keys. Which keys, and where they go: how to remove a car radio.

Tips for your Subaru Impreza

  • On a Clarion radio, type in the last four numbers of the barcode on the label.
  • If there are two barcodes, use the lower one.
  • Japanese imports often have no code at all — if the radio never asks for one, nothing is locked.

Subaru Impreza radio code questions

Where is the serial on an Impreza radio?

On the label on the radio case, so the radio has to come out.

My Impreza is an import.

Subaru only gave UK cars the code feature, so many imports simply don’t ask for one.

Which numbers do I type in?

The last four of the barcode on a Clarion radio. The free check works it out if you type the whole thing.

Which radio does my Subaru Impreza have?

It depends on the year. 1992–2000 (First Impreza): Subaru radios built by Clarion, some Philips radios. 2000–2007 (Second Impreza): Subaru radios built by Clarion. Radios were often swapped, so the serial on yours is what counts.

Do I have to take the radio out of my Subaru Impreza?

Yes: the serial is on the label, not the screen. It comes out with a pair of radio removal keys.

How do I enter the code on a Subaru Impreza?

Presets 1 to 4 set each digit. Clarion codes only use the digits 1 to 6, so if one of yours is outside that range the barcode has been misread.

Another Subaru?
