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

|---|---|---|
| Dashboard, driver side | Through the windshield, bottom corner | Easiest to check before you touch anything |
| Driver door jamb | Open the door, sticker on the pillar | Also lists tire pressures and build date |
| Under the hood | Firewall or strut tower plate | Survives a windshield replacement |
| Title and insurance | Paper documents | Must match the car — a mismatch means fraud or a swapped panel |

Frequently asked questions
Is this Mercedes-Benz S-Class VIN decoder free?
Yes, with no account. Besides the year, plant and build characters it shows 87 recall campaigns and 9 owner complaints NHTSA holds on the Mercedes-Benz S-Class.
Why does my S-Class VIN start differently from another S-Class?
Because the Mercedes-Benz S-Class was built under several maker codes, by plant and period. Across the Mercedes-Benz S-Class VINs on record we see 3 of them: WDB (2006–2006), WDD (2007–2011), W1K (2021–2022). Each is genuine for its years.
What year is my S-Class by its VIN?
Read position 10: a 2026 S-Class carries T, a 2025 S-Class carries S, a 2024 S-Class carries R. A 1996 and a 2026 share T; position 7 tells them apart, a number for 1980–2009 and a letter from 2010 on.
Where was my S-Class built?
Position 11 names the plant. Across 9 dated Mercedes-Benz S-Class VINs it reads A 100%.
What does position 4 mean on a Mercedes-Benz S-Class VIN?
It is part of the maker's own build code, so read it against this model, not a generic chart. On 213 Mercedes-Benz S-Class VINs here, U is the most common character in position 4, on 36% of them.
What if the VIN on the dashboard doesn't match the door jamb?
On a Mercedes-Benz S-Class check the prefix first: most genuine ones open with W1K, WDD or WDB. A plate that starts with anything else, or disagrees with the other copies of the number, needs documents checked before any money changes hands.
