What Does a VIN Tell You? How to Decode All 17 Characters, Whether a VIN Check Shows a Salvage Title, and What It Can't Tell You (2026)
October 7, 2026
Short answer: a VIN tells you who built the car, what kind of car it is, its model year, which plant built it and its serial number. That is all it was ever designed to do. A free VIN check can also flag a reported theft or salvage record. What a VIN cannot tell you is how serious a car's history was, what was repaired, or whether the price is fair. Here is every one of the 17 characters, decoded.
Key takeaways
- Every VIN is 17 characters under the federal standard, 49 CFR Part 565, for most vehicles built after April 30, 2009.
- The letters I, O and Q are never used, so a VIN with one in it was copied wrong.
- The 10th character is the model year; the 9th is a check digit that catches typos.
- A free check from NICB can flag a reported salvage-declared or stolen vehicle, up to five searches a day per IP address, as published.
- For a rebuilt title car, the VIN does not grade the history. A ReVroom Report does.
What does each part of a VIN mean?
Short answer: think of a VIN like a mailing address read from the country down to the house number. The first characters say who made it, the middle says what it is, and the end says which one it is.
| Position | What it means | Example of what it tells you |
|---|---|---|
| 1 to 3 | World manufacturer identifier (WMI) | Who built the car and where the maker is registered |
| 4 to 8 | Vehicle descriptor section | Model line, body style, engine and other attributes the maker encodes |
| 9 | Check digit | A math check that catches a mistyped VIN |
| 10 | Model year | L is 2020, R is 2024, T is 2026 |
| 11 | Assembly plant | Which factory built it |
| 12 to 17 | Production sequence number | This specific car's serial number |
Source: the federal VIN standard, 49 CFR Part 565, as read October 7, 2026. Low-volume manufacturers use a slightly different layout in positions 12 to 17.
Which character of the VIN is the model year?
Short answer: the 10th. It runs through letters and numbers in a fixed cycle, skipping the ones that look like other characters.
| 10th character | Model year |
|---|---|
| A | 2010 |
| B | 2011 |
| C | 2012 |
| D | 2013 |
| E | 2014 |
| F | 2015 |
| G | 2016 |
| H | 2017 |
| J | 2018 |
| K | 2019 |
| L | 2020 |
| M | 2021 |
| N | 2022 |
| P | 2023 |
| R | 2024 |
| S | 2025 |
| T | 2026 |
Handy at a glance: if a listing says 2022 and the 10th character is an L, something does not match, and that is worth a question before you go any further.
Can a VIN check tell you if a car has a salvage title?
Short answer: it can flag a reported one. NICB's free VINCheck searches for vehicles reported stolen and not recovered and for salvage-declared vehicles from participating insurers, and it allows up to five searches in 24 hours per IP address, as published. If the title is already branded rebuilt, the title itself will say so.
What a check like that does not do is tell you how serious the history was. A salvage flag on a hail car and a salvage flag on a car with structural repairs look the same. For the step-by-step on checking a title, see our guide to how to tell if a car has a salvage or rebuilt title.
What do the free VIN tools show?
| Tool | What it shows, as published | What it does not show |
|---|---|---|
| NHTSA VIN decoder | Information reported by the manufacturer, such as the build plant and country | Anything that happened after the car left the factory |
| NICB VINCheck | Free check for theft not recovered and salvage-declared records from participating insurers | How serious the history was or what was repaired |
| A paid history report | Its own mix of records; read what each provider says it covers | An in-house grade of a rebuilt car's history |
| ReVroom Report (rebuilt and branded titles) | In-house severity grade, a severity graphic, an estimated savings percentage, and where and when the car was auctioned | It is not a vehicle history report and does not replace one; photos live on the listing |

What can't a VIN tell you about a rebuilt title car?
Short answer: the three things a rebuilt title buyer cares about most: how serious the history was, what was fixed, and whether the price is right for it.
That is the gap a ReVroom Report fills. It grades the history minor, moderate or severe in-house, shows a severity graphic with highlights, estimates the savings against comparable clean title cars, and tells you where and when the car was auctioned. On the listing itself you see what was repaired, with photos where they are available. And you can skip the guesswork entirely by shopping minor-graded cars only.
Our take
A VIN is a birth certificate, not a medical chart. It is the first thing I check on any car, because a mismatch there ends the conversation early. But on a rebuilt title car, the real question is what happened after the birth certificate was printed, and that takes a grade, not a decoder.
Frequently asked questions
What does a VIN tell you?
The 17 characters identify the manufacturer (positions 1 to 3), the vehicle's attributes such as model, body and engine (4 to 8), a check digit (9), the model year (10), the assembly plant (11) and the production serial number (12 to 17), under the federal VIN standard in 49 CFR Part 565.
Which letters are never used in a VIN?
I, O and Q, so they cannot be confused with the numbers 1 and 0. If a VIN contains one of them, it has been copied wrong.
Which digit of the VIN is the model year?
The 10th. It cycles through letters and numbers, with A standing for 2010, B for 2011 and so on; R is 2024, S is 2025 and T is 2026.
Can a VIN check tell you if a car has a salvage title?
A free check can flag it if the record was reported. NICB's free VINCheck looks for vehicles reported stolen and not recovered and for salvage-declared vehicles from participating insurers, and it allows up to five searches per 24 hours per IP address, as published. It does not tell you how severe the history was or whether the repair was done well.
Is NHTSA's VIN decoder free?
NHTSA's decoder is publicly accessible on its website, and it shows information reported by the manufacturer, such as the build plant and country.
What can't a VIN tell you about a rebuilt title car?
How serious the original history was, what was repaired, and how the price compares with a clean title version. For rebuilt and branded title cars, a ReVroom Report adds an in-house severity grade, a severity graphic, an estimated savings percentage and where and when the car was auctioned. It is not a vehicle history report.
