Where to find the VIN on a Mercedes-Benz A-Class

A Mercedes-Benz A-Class VIN normally opens with WDD; the full number sits in four places, and all four must match.

Frequently asked questions

Is this Mercedes-Benz A-Class VIN decoder free?

Yes, with no account. Besides the year, plant and build characters it shows 16 recall campaigns and 6 owner complaints NHTSA holds on the Mercedes-Benz A-Class.

Why does my A-Class VIN start differently from another A-Class?

Because the Mercedes-Benz A-Class was built under several maker codes, by plant and period. Across the Mercedes-Benz A-Class VINs on record we see 2 of them: WDD (2019–2019), W1K (2020–2022). Each is genuine for its years.

What year is my A-Class by its VIN?

Read position 10: a 2022 A-Class carries N, a 2021 A-Class carries M, a 2020 A-Class carries L.

Where was my A-Class built?

Position 11 names the plant. Across 6 dated Mercedes-Benz A-Class VINs it reads W 50%, J 50%.

What does position 4 mean on a Mercedes-Benz A-Class VIN?

It is part of the maker's own build code, so read it against this model, not a generic chart. On 21 Mercedes-Benz A-Class VINs here, 3 is the most common character in position 4, on 100% of them.

What if the VIN on the dashboard doesn't match the door jamb?

On a Mercedes-Benz A-Class check the prefix first: most genuine ones open with WDD or W1K. A plate that starts with anything else, or disagrees with the other copies of the number, needs documents checked before any money changes hands.
