1963-1967 Accessory codes


Using the charts below, you can decode some or all of your ACC codes on your 1963-1967 Chevrolet.


How to read these codes:

Example: E2EM3C5V

The first E is part of group 1 (note-a 1 is never used on the tag for group 1) By looking on the Group 1 chart below this tells us that the car has tinted windows.

The next digit shows group 2 followed by code E & M. Looking at code E & M on the Group 2 chart below shows that this car has air conditioning and a powerglide.

Group 3 is next followed by code C for padded dash

Next is Group 5 code V. Notice there is nothing for group 4. This particular car has no options from group 4 so it is omitted. Looking at the chart under Group 5, we see that code V is for seat belts.

* Note-some plants didn't use the codes listed below but would put the actual RPO numbers on the tag instead. (example: A01, D55, etc) If you car has this type, go to the RPO codes page.
