About Plymouth

Plymouth was launched by Walter P. Chrysler in the summer of 1928 as Chrysler Corporation’s entry-level brand, built to compete directly with Ford and Chevrolet in the low-priced segment. The name is credited to Chrysler executive Joe Frazer, who suggested it after invoking Plymouth Binder Twine, a well-known American rope and cordage brand of the era; the twine maker’s own name traced back to Plymouth, Massachusetts. The car sold a million units within six years and helped make Chrysler the third member of Detroit’s “Big Three.”

Plymouth’s high-water mark came in 1973, when sales approached 750,000, driven largely by the muscle car lineup that still defines the brand’s reputation today: the Barracuda, Road Runner, GTX, Fury, Duster, and Valiant. Those cars predate the modern 17-character VIN standard, which is why classic Plymouths use shorter serial numbers rather than a standard VIN. In the 1990s Chrysler gave the brand one more push with the Neon and, later, the retro-styled Prowler, but it wasn’t enough to reverse decades of declining share. DaimlerChrysler announced in November 1999 that Plymouth would be retired at the close of the 2001 model year, and the final Plymouth ever built, a silver Neon LX, rolled off the line at Belvidere Assembly in Belvidere, Illinois, on June 28, 2001.

Plymouth was always a Chrysler Corporation brand, not an independent automaker, and many Plymouth models were close mechanical siblings of Dodge and Chrysler-badged counterparts built on shared platforms and, in some cases, the same assembly lines. VinDecoderPlus maintains separate Dodge and Chrysler VIN decoder hubs for those brands; this page covers Plymouth-badged vehicles specifically.

Plymouth WMI codes (positions 1-3)

The first three characters of your VIN, the World Manufacturer Identifier (WMI), tell you who built the vehicle and where. The WMI is assigned by SAE International on behalf of ISO. Plymouth never had its own manufacturing arm; its WMIs were registered to Chrysler Corporation and its successors (now part of Stellantis). Here are the WMIs confirmed on Plymouth vehicles:

If your Plymouth VIN begins with one of the codes above, it’s a genuine factory Plymouth. A VIN starting with an unlisted WMI may indicate a data-entry error, a rebadge, or a counterfeit plate. Decode the full VIN with the tool above to confirm.

How to read a Plymouth VIN: position by position

Every Plymouth built from the introduction of the modern standard in 1981 through the brand’s final year in 2001 uses the ISO 3779 17-character VIN format. The 17 characters split into three blocks:

Here is what each position means specifically on a Plymouth:

Positions 1-3: World Manufacturer Identifier

See the WMI table above. Plymouth’s US-built cars (1P3, 1P4) came primarily out of Belvidere, Illinois and Fenton, Missouri, while Canadian-built Voyager minivans (2P4) came from Windsor, Ontario. The country code at position 1 tells you where the vehicle was assembled, not where the Plymouth nameplate itself originated.

Positions 4-8: Vehicle Descriptor Section (VDS)

These five characters encode the model series, body style, and restraint system, with one position typically identifying the engine. Because Plymouth shared platforms with Dodge and Chrysler, the VDS logic on a Neon or Voyager closely mirrors the equivalent Dodge or Chrysler model of the same model year.

Position 9: Check digit

The check digit is the most important single character in any VIN. It is calculated from the other 16 characters using a fixed weighting table and modulo-11 math. If even one character of a Plymouth VIN is mistyped, the check digit will not match, and any compliant decoder, DMV, or insurance system will flag the VIN as invalid.

Position 10: Model year

The 10th character maps to a model year. Since Plymouth’s 17-character VIN era runs only from 1981 to 2001, that’s the full range you’ll ever need for a Plymouth:

The letters I, O, and Q are never used in any VIN, including Plymouth, because they look too similar to the digits 1 and 0.

Position 11: Assembly plant

The single character at position 11 identifies the specific factory. Confirmed Plymouth plant codes: D (Belvidere, Illinois, home of the Neon and the final Plymouth ever built), B (Fenton, Missouri, Voyager and Grand Voyager), R (Windsor, Ontario, Voyager and Grand Voyager for the Canadian-built run). Earlier Plymouth muscle cars like the Road Runner, GTX, and Barracuda came out of Lynch Road and Hamtramck in Michigan, the St. Louis area plant in Fenton, and Los Angeles Assembly in Maywood, California, though those predate the 17-character VIN and used shorter, plant-specific serial formats.

Positions 12-17: Serial number

The final six characters are the production sequence number stamped on your specific Plymouth as it rolled off the line. Combined with the previous 11 characters, this makes every Plymouth VIN globally unique.

Where to find the VIN on a Plymouth

You can find your Plymouth VIN in several places. The lower-left windshield and the door jamb are the easiest to read; the others are useful when one of those labels has been damaged or replaced.

• Lower-left corner of the windshield, visible from outside
• Driver’s side door jamb sticker (VIN, type code, paint, interior code)
• Stamped on the engine block or firewall under the hood
• Vehicle title, registration, and old dealership paperwork

If your Plymouth is a classic built before 1981, such as a Barracuda, Road Runner, GTX, or early Valiant, the chassis number is shorter than 17 characters and follows an older Chrysler-specific format rather than the modern VIN standard. For pre-1981 vehicles, use our classic car VIN decoder guide.

Check Plymouth recalls and safety information

Plymouth has had no dealer network of its own since the brand was discontinued in 2001, so open and historic recalls on Plymouth vehicles are now tracked and processed through Stellantis’s Mopar recall system, the same system used for current Jeep and Ram vehicles on this site. The fastest way to check a specific Plymouth:

1. Decode the VIN with the tool above to confirm the model and model year
2. Cross-reference the 17-character VIN with the Mopar recall lookup and NHTSA’s own recall database
3. Review any open safety actions and contact your nearest Chrysler, Dodge, Jeep, or Ram dealer for free repair, since those dealers now handle warranty and recall work for retired Chrysler Corporation brands including Plymouth

Recalls are repaired free of charge by the manufacturer regardless of vehicle age or ownership history, even for a brand that hasn’t sold a new car since 2001.

Frequently asked questions

How do I decode my Plymouth VIN?

Type the 17-character VIN from your Plymouth’s windshield, driver-side door jamb, or vehicle title into the decoder at the top of this page. Results return in seconds and include make, model, model year, body style, engine family, transmission, plant of origin, and open NHTSA recalls. No registration is required.

Where is the VIN on my Plymouth?

The two easiest spots are the lower-left corner of the windshield (visible from outside the car) and the driver-side door jamb sticker. Both locations were required by federal labelling regulation on every road-going Plymouth sold in North America from the early 1980s onward.

Is the Plymouth VIN decoder free?

Yes. VinDecoderPlus decodes every Plymouth VIN free of charge with no sign-up or credit card. Full vehicle history reports, including ownership records, accident history, and odometer history, are available as an optional paid upgrade.

What does the VIN tell me about my Plymouth?

A VIN decode confirms the original factory configuration of your Plymouth: model, year, body style, engine, transmission, trim level, factory options, country and plant of origin, and any recall actions issued against that VIN. It does not record colour (which is on the build sheet), current mileage, accident history, or ownership chain. For those, you need a paid vehicle history report.

Can a Plymouth VIN be faked?

The 17 characters themselves can be retyped, but the check digit at position 9 makes silent tampering nearly impossible: any single-character change breaks the math. This matters more with a discontinued brand like Plymouth, where fewer buyers are used to checking a VIN closely. If you suspect a cloned VIN, our guide how to check if a car is stolen by VIN walks through the next steps.
