Unlock Full VIN ReportEvery S Class since the W126 has a 17 character VIN, also called the chassis number. It sits in the same places on most cars. On a car this valuable, check the number on the windshield, the door pillar and the paperwork all match before anything else.
A US S Class has two numbers for the same car. The VIN on the title, and a Mercedes identification number, called the FIN, on the data card. Both end in the same six digit serial number.
Mercedes uses two formats. US and Canadian cars use a VIN with a check digit and a model year. UK and European cars use the FIN, which puts the Mercedes model number straight into the number, so a W222 shows 222 in positions 4 to 6. Every US S Class was built in Sindelfingen, so position 11 is almost always A.
Example US format: W1K6G7GB4MA123456, a 2021 W223 S 580 4MATIC built in Sindelfingen
On the W220, positions 6 and 7 of a US VIN match the end of the model number. WDBNG70J is a 220.170 S 430.
Example FIN: W1K2231761A123456, a W223 S 580 4MATIC long wheelbase. Model number 223.176. The same car in the US carries VIN W1K6G7GB4MA123456
The FIN doesn't carry a model year or a check digit. Use the V5C first registration date or the data card for the year.
These come from real US VINs and Mercedes VIN filings. The characters after the manufacturer code tell you the generation, the body and on newer cars the exact model.
| VIN starts | Model | Years |
|---|---|---|
| WDBC | W126 S Class, like the 300 SD, 420 SEL and 560 SEL | 1981 to 1991 |
| WDBG | W140 S Class, like the S 320, S 420, S 500 and S 600 | 1992 to 1999 |
| WDBNG70J | W220 S 430 | 2000 to 2006 |
| WDDNG71X | W221 S 550 | 2007 to 2013 |
| WDDUG8GB | W222 S 560 4MATIC | 2018 to 2020 |
| WDDUG7D | W222 S 560e plug in hybrid | 2019 to 2020 |
| WDDUG8J | W222 AMG S 63 4MATIC | 2018 to 2020 |
| WDDUX8G, WDDUX8A | X222 Mercedes-Maybach S 560 4MATIC and S 650 | 2018 to 2020 |
| WDDXJ8J, WDDXJ7K | C217 AMG S 63 and S 65 coupe | 2018 to 2021 |
| W1K6G6DB | W223 S 500 4MATIC | 2021 on |
| W1K6G7GB | W223 S 580 4MATIC | 2021 on |
Position 10 on US and Canadian VINs only. The 17 character VIN started with the 1981 model year, the same year the W126 arrived in the US.
Mercedes model years start mid year, so an S Class built in summer 2020 can be a 2021 car.
Every S Class generation has a W number, and the body styles get their own letter. W is the standard wheelbase sedan, V the long wheelbase, C the coupe and A the cabriolet. Mercedes-Maybach versions use X on the W222 and Z on the W223. US cars from the W221 on are long wheelbase.
W126, C126
Sedan in two lengths plus the SEC coupe. The 560 SEL and 560 SEC are the collector cars, and the 300 SD diesel was common in the US.
W140, V140, C140
The big, over engineered S Class, with the first V12 in the S 600. The coupe was later sold as the CL.
W220, V220
Smaller and lighter, with AIRMATIC as standard. The S 55 AMG and twin turbo S 600 sat on top. Sold in the US from 2000 to 2006.
W221, V221
The S 550 was the core US car. The S 63 AMG and S 65 AMG sat on top, with the S 400 Hybrid and S 350 BlueTEC later on.
W222, V222, C217, A217, X222
Sedan, coupe, cabriolet and the return of Maybach as the X222. Facelifted for 2018 with the S 560 and new engines.
W223, V223, Z223
Sedan only, with MBUX screens, rear axle steering as an option and the Maybach Z223. The S 500 and S 580 are the US cars.
| Chassis code | Body | How to confirm it |
|---|---|---|
| W126 to W223 | Sedan, standard wheelbase | The FIN shows the number in positions 4 to 6 |
| V140, V220, V221, V222, V223 | Sedan, long wheelbase | The model number on the data card, and an L in older badges like 560 SEL |
| C126, C140, C217 | Coupe | Two doors. A US C217 VIN shows XJ. |
| A217 | Cabriolet | Soft top. The model number on the data card proves it. |
| X222, Z223 | Mercedes-Maybach | A US X222 VIN shows UX. Check the data card for the Maybach model number. |
Mercedes paint codes are three digits, and the data card often adds a letter, so Brilliant Silver shows as 744 or 744U. The code is on the data card and on the data plate in the door pillar or under the hood, so a resprayed S Class is easy to spot.
Swatches are a guide only, and designo and Maybach offered many more colors and two tone paint to order. The code on your car is the proof.
Not from the 17 characters. The VIN gives you the generation, the body, the engine on US cars and the plant, but not the options, the suspension or the rear seat package.
Mercedes keeps a data card for every car. It lists the FIN, the VIN on US cars, the engine and transmission numbers, the paint code, the upholstery code and every option code. Here's how to get it.
Ask the service desk to print the vehicle data card from the VIN. It lists every factory option code with a description.
Parts staff look up the data card to order the right parts, so they can often read out the option codes too.
The original US window sticker or the UK order confirmation lists the packages and options by name. Match them to the codes below.
Sit in the back, check the rear seat controls and screens, look up at the roof and check the suspension menu. They back up the paperwork.
Copy the codes from the data card and paste them into the decoder below to get your full S Class options list.
Paste the option codes from your S Class data card and get a readable options list, grouped by system. Paint codes with a letter on the end, like 744U, work too.
Separate codes with spaces, commas or new lines.
Search by code or keyword. Covers option codes, packages, paint and engine codes.
Type a code or keyword to see matches.
Tip: click any code to copy it. Some codes changed meaning between generations, so check anything important against the data card.
The S Class has carried six, eight and twelve cylinder engines, diesels and hybrids. The badge doesn't always match the engine size, so the engine code on the data card is the one to trust.
| Generation | Common US models | Engines |
|---|---|---|
| W126 | 300 SD, 300 SE, 420 SEL, 560 SEL, 560 SEC | OM617 diesel, M103 straight six, M116 and M117 V8 |
| W140 | S 320, S 420, S 500, S 600 | M104 straight six, M119 V8, M120 V12 |
| W220 | S 430, S 500, S 55 AMG, S 600 | M113 V8, M113 supercharged, M137 then M275 V12 |
| W221 | S 550, S 600, S 63 AMG, S 65 AMG, S 400 Hybrid, S 350 BlueTEC | M273 V8, M275 V12, M156 then M157 V8, M272 V6 hybrid, OM642 diesel |
| W222 | S 450, S 550, S 560, S 560e, AMG S 63, S 600 | M276 V6, M278 then M176 V8, M157 then M177 V8, M279 V12 |
| W223 | S 500, S 580, AMG S 63 E Performance, Maybach S 680 | M256 straight six, M176 V8, M177 V8 hybrid, M279 V12 |
Most S Classes ride on AIRMATIC air suspension, code 489. V12 and some V8 cars use hydraulic Active Body Control, code 487. Both are expensive to fix, so check which one the car has before you buy.
A Mercedes-Maybach has its own model number and, on the W222, its own US VIN letters, UX instead of UG. Badges and wheels are easy to add, the data card isn't.
An S Class is full of complex systems, and an older one costs as much to run as a new one. The chassis code and the option codes tell you what to check.
| Generation or system | What to look for | Why it matters |
|---|---|---|
| W126 V8 | Timing chain and guide wear, rattle on start up | A broken guide can wreck the engine. Ask when the chain and guides were done. |
| W140 from 1993 | Engine wiring harness insulation breaking down | Causes misfires and running faults. Ask if the harness was replaced. |
| AIRMATIC, code 489 | Car sitting low after parking, compressor running on | Air struts and compressors wear out. Check the ride height after the car has sat overnight. |
| Active Body Control, code 487 | Warning messages, leaks, a hard or bouncy ride | Hydraulic pumps, struts and lines are expensive. Get it checked by a specialist. |
| V12 engines | Ignition coil packs, oil leaks, high service costs | Everything costs more on a V12. Ask for the full service history. |
| W223 electronics | Screen and software faults | Make sure every software update and campaign was done. |
Recall campaigns differ by market and generation, so check through the channel that covers where the car was sold.
Use the DVSA vehicle recall checker on GOV.UK with the make, model and year, then ask a Mercedes dealer to run the VIN.
Run the VIN through the decoder above for NHTSA recall records, or use the NHTSA recall lookup or Mercedes' own recall check.
An S Class imported from another market may never have had recall work done. A Mercedes dealer can check the VIN against every open campaign.
On a W223, many campaigns are software updates. Ask for proof every recall and update was completed, not just booked.
The full list behind the data card decoder, grouped by system. Codes vary by generation, year and market, so verify anything important against your own data card.
S Class packages changed a lot by year and market. Newer data cards also list engine and drive as codes, like M176 and M005.
Engine codes show on the data card and the engine itself. Newer data cards list the engine as a code too, like M176.
Swatches are a guide only. Data cards often add a letter, so 744U is paint code 744. The decoder accepts both.
Suspension is the most expensive thing to fix on an older S Class, so check which system the car has.
Rear seat equipment matters on an S Class, so check the back as well as the front.
Roof and light codes are easy to check by looking at the car.
Assistance systems are mostly software and sensors, so check the code, then check the menus.
These codes don't add equipment, but they explain where and when a car was built for.
The names you'll see in listings, on order forms and in the menus. Search any of them in the decoder above to find the code behind it.
On a plate at the bottom of the windshield, on the data plate in the door pillar, and stamped into the body. It's also on the V5C in the UK and the title in the US.
The FIN is the Mercedes identification number, with the model number built in. UK and European cars use the FIN as their VIN. US cars have a separate VIN on the title, and both numbers end in the same six digit serial.
On a UK or European car, read positions 4 to 6. WDD222 is a W222 and W1K223 is a W223. On a US car, UG after the manufacturer code is a W222 and 6G is a W223.
WDDUG is the start of a US W222 S Class sedan VIN, sold from 2014 to 2020. The next characters show the engine, like 8G for an S 560 4MATIC.
W126, W140, W220, W221, W222 and W223. V marks the long wheelbase, C the coupe, A the cabriolet, and X222 and Z223 the Mercedes-Maybach.
Every US S Class from the W221 on is long wheelbase. On older cars, an L in the badge like 560 SEL means long. The model number on the data card proves it either way.
Not from the 17 characters alone. The options are on the Mercedes data card, which a dealer can print from the VIN. Paste the option codes into the decoder above.
Look on the data card. Code 489 is AIRMATIC air suspension and code 487 is Active Body Control.
US S Classes were built in Sindelfingen, Germany, which shows as A in position 11 of the VIN.
