VW Bus M-Plate Decoder

Read the whole plate.the way it's actually stamped.

Real M-plates are a few continuous lines of stamped text, not a row of separate boxes - and the option codes share lines with the date, destination, model, paint and chassis number. Type in what your plate shows and watch it lay out the same way as the real thing.

Splitscreens built before October 1958 carried their codes on a plate in the engine bay in a different layout - this tool covers the standard riveted M-plate used from late 1958 on.

How it works

How to read an M-plate.

Splitscreen, 1959-1967
Where to look

The plate is riveted behind the right-hand front seat on most models (bench, walk-thru, or single-cab position depends on your layout).

Bay Window, 1968-1979
Where to look

Early Bays (68-76): behind the driver's seat. Later Bays (77-79): on the fresh-air vent under the dash, left side. It's a small stamped-metal tag, easy to miss under grime.

Why it's not boxes
Stamped lines, not a grid

A real plate has 3-4 continuous stamped lines. Option codes often share a line with the date, engine code, or paint code - there's no dividing box between them.

A quick note on accuracy. This tool's layout was checked against photographed real plates and the most detailed classic-bus reference archives (TheSamba, Type2.com), not just a data-entry form. Option codes, export-destination codes, and the date decode from sourced references. Bay Window model/body-type codes (1968-79) are cross-checked against TheSamba's Transporter Type 2 model-code archive - only codes with a confirmed meaning are decoded, everything else is shown as recorded rather than guessed at. Paint/interior splits into lower-color, upper-color, and upholstery per the documented format, though exact color names aren't charted yet. Engine/gearbox codes are recorded exactly as stamped but don't have a verified meaning table yet - and one field on 1970-79 plates is a genuine unsolved mystery: even the researchers who catalog these plates don't know what it means. Beetle plates use a related but separately-documented code set - try our Beetle M-Code Decoder instead. When it matters - originality, a build sheet, a restoration - give the shop a call and we'll help you cross-check it by hand.
Questions

Bus M-plates, answered.

Where do I find the M-plate on a VW Bus?

On Splitscreens (1959-1967) the plate is riveted behind the right-hand front seat on most models (bench, walk-thru, or single-cab position depends on your layout). On early Bay Windows (68-76) it's behind the driver's seat; on later Bays (77-79) it's on the fresh-air vent under the dash, left side. It's a small stamped-metal tag, easy to miss under grime.

Why doesn't a real M-plate look like a row of boxes?

A real plate has 3-4 continuous stamped lines. Option codes often share a line with the date, engine code, or paint code — there's no dividing box between them.

Does this tool cover pre-October 1958 Splitscreens?

No. Splitscreens built before October 1958 carried their codes on a plate in the engine bay in a different layout — this tool covers the standard riveted M-plate used from late 1958 on.

Can I use this tool on a Beetle plate?

No. Beetle plates use a related but separately-documented code set — use our Beetle M-Code Decoder instead.

How complete is the Bus M-plate decoding?

Option codes, export-destination codes, and the date decode from sourced references. Bay Window model/body-type codes (1968-79) are cross-checked against TheSamba's Transporter Type 2 model-code archive — only codes with a confirmed meaning are decoded, everything else is shown as recorded rather than guessed at. Engine/gearbox codes are recorded exactly as stamped but don't have a verified meaning table yet.
