Buying a used car always comes with risks, and one of the key points is checking the actual year of manufacture. Even the PTS may contain incorrect data, and altered body numbers or fake documents are not uncommon in the secondary market. VIN code (Vehicle Identification Number) is a unique “passport” of the car, which stores information about the production date, the country of assembly and other critical parameters. But how exactly can you isolate the exact month and year from 17 characters? Spoiler: it's easier than it seems if you know the algorithm.

Many people mistakenly think that it is enough to look at the 10th character of the VIN - and here it is, the true year. In practice, everything is more complicated: manufacturers use different encoding standards, and some brands (for example, Mercedes-Benz or BMW) can encrypt the date in other positions. In this article we will analyze 5 working methods, how to find out the production date by VIN, including free online services, official databases and “secret” symbols for Japanese and American cars. You will also learn why data from different sources may differ and how to avoid fraud.

What is a VIN code and where to look for it on a car

VIN (Vehicle Identification Number) is a 17-digit alphanumeric code that is assigned to a car at the factory and remains unchanged throughout its “life.” It consists of three parts:

  1. WMI (World Manufacturer Identifier) — the first 3 characters indicating the manufacturer and country;
  2. VDS (Vehicle Descriptor Section) — symbols from 4 to 9, describing the model, body type, engine;
  3. VIS (Vehicle Identifier Section) — the last 8 characters, where the year, plant and serial number are encrypted.

It is in VIS The release date is hidden, but its location depends on the manufacturer's standard.

Where is the VIN physically located on the car:

  • 🔹 On the sign under the windshield (driver’s side) is the most common place;
  • 🔹 In the driver's door opening (on a sticker or embossed on the body);
  • 🔹 Under the hood (on the side members or partition of the engine compartment);
  • 🔹 In the trunk (on some models Volkswagen and Audi).

⚠️ Attention: If the VIN on the plate and in the door opening do not match, this is a sign that the number has been altered. It is better not to buy such a car or to carefully check it through the traffic police.

Also the code is duplicated in the documents:

  • 📄 B PTS (string “VIN” or “Identification number”);
  • 📄 B STS (if the car is registered in Russia);
  • 📄 In the OSAGO insurance policy.

How to decipher the production date from the 10th character of the VIN

In most cases the year of production is encrypted in the 10th character of the VIN (if you count from left to right). However, there are nuances here:

  1. The symbol may be number (0–9) or Latin letter (A–Y, except I, O, Q).
  2. The encoding changed in 1980, 2000 and 2010 - this is important for older cars.
  3. Some brands (eg Toyota or Honda) use 11th character for a month.

Here is a table of decoding of the 10th character for machines produced with 2010 to 2039:

Symbol Year of manufacture Example (VIN)
A 2010 JT2AKFUH0A123456
B 2011 WDBBFA65JSF123456
C 2012 5XYZC3AB7CG123456
D 2013 2HNYD2H6GHM123456
E 2014 KNAEN4A76EA123456

For cars 1980–2009 a different table is used (letters A–Y correspond to 1980–2009, numbers 1–9 correspond to 2001–2009). For example, VIN with the symbol «Y» in the 10th position means that the car was produced in 2000, and «9» - in 2009.

⚠️ Attention: If the 10th character contains «0», this could mean either 2000, or 2010 — additional verification through databases is required.

Why are there no letters I, O, Q in the VIN?

These characters are excluded due to their similarity to the numbers 1 and 0, to avoid confusion when reading the code.

Features of determining the date for Japanese and American cars

Manufacturers from Japan and USA often use non-standard VIN formats, where the date may be encrypted differently. Let's look at the key differences:

Japanese cars (Toyota, Nissan, Honda, Mazda):

  • 🔹 10th character - year (as in standard VIN);
  • 🔹 11th character - month (letter A–L for January–December, where A=January, B=February, ..., L=December).

Example: VIN JT2BKFUH0A123456 stands for February 2011 (B=2011, K=November).

American cars (Ford, Chevrolet, Dodge):

  • 🔹 10th character - year;
  • 🔹 7th character - model year (may differ from the actual year of manufacture by ±1 year).

For example, Ford Mustang with VIN 1FAFP42X3NF123456 (F=2015) could have been released at the end of 2014 as a 2015 model.

German cars (BMW, Mercedes-Benz, Volkswagen):

  • 🔹 The date can be encrypted in 11–12 characters;
  • 🔹U BMW the month is sometimes coded as a number (1–9=A–I, excluding 0).

💡

If you check Toyota or Lexus, pay attention to first 3 characters of VIN: if they start with JT, this is guaranteed Japanese assembly. For American assembly it will be 5T or 4T

Free online services for checking VIN

If manual transcription seems difficult, you can use online services. Here are the top 5 proven resources:

1. Official databases of manufacturers

2. Universal decoders

⚠️ Attention: Some services (for example, CarVertical or AutoDNA) offer paid reports. Free versions often show only basic year information, without the month.

Why release date information may differ

Sometimes VIN decoders or documents show different years. Here are the main reasons:

1. Model year vs. actual year

  • 📅 The car can be produced in December 2022, but sold as a model 2023;
  • 📅 For example, Ford F-150 The 2023 model year could roll off the assembly line in October 2022.

2. Restyling or generation change

  • 🔄 The car may be released at the end of 2019, but belong to the 2020 model due to the update;
  • 🔄 This happens with Volkswagen Golf or Skoda Octavia.

3. Database errors

  • 🖥️ Some decoders use outdated algorithms (for example, for cars before 2010);
  • 🖥️ Official services (for example, traffic police) may display the year of registration rather than the year of issue.

4. “Gray” assembly or counterfeit

  • 🚨 The car could have been assembled unofficially (for example, Chinese replicas);
  • 🚨 There may be fake characters in the VIN (often found in Land Rover or Porsche).
💡

If the difference between the data from the VIN and the PTS is more than 1 year, this is a reason to suspect forgery or an error in the documents.

How to check the release date through the traffic police and other official sources

For maximum accuracy, it is worth checking with government databases. Here are 3 reliable ways:

1. Check through the traffic police website

  • 🔗 Go to car check service;
  • 🔢 Enter VIN or license plate number;
  • 📄 The report will indicate year of manufacture (but not a month!).

2. Request to Rosstandart

  • 📧 Write a letter to info@gost.ru asking for VIN information;
  • 📄 Attach a scan of the PTS;
  • ⏳ The answer will come within 10-14 days (free of charge).

3. Contact an official dealer

  • 🏢 Find a dealer of your car brand;
  • 🔧 Provide VIN and ask for an extract from the factory database;
  • 💰 The service may be paid (from 500 to 2000 rubles).

⚠️ Attention: If the traffic police refuses to register a car due to a discrepancy between the year in the VIN and the title, an examination will be required. It can be carried out in accredited centers (for example, US or FSUE "Standardinform").

What to do if the date in the VIN does not match the documents

Discrepancies in dates are a red flag. Here is the algorithm of actions:

1. Recheck the VIN

  • 🔍 Check the code on the body, in the documents and on the sign;
  • 📸 Take pictures of all the places where it is indicated;
  • 🖥️ Use 2-3 online decoders for cross-validation.

2. Order a car history

  • 📊 Services CarVertical, AutoDNA or Carfax will show actual mileage, accidents and number of owners;
  • 💰 Report cost: 300–1000 rubles.

3. Contact an auto expert

  • 🔧 An expert will check the body for traces of VIN interruption;
  • 📋 Will draw up an act with a conclusion (cost: 2000–5000 rubles).

4. Submit a request to the traffic police

  • 📝 Write an application to check the legality of the car;
  • 🚔 You will be provided with data from the federal database.
💡

If the seller refuses to provide a VIN for verification or a “fresh” car document (issued less than 3 months ago), this is a reason to doubt the purity of the transaction.

FAQ: Frequently asked questions about the release date by VIN

Is it possible to find out the exact date of manufacture using the VIN?

No, only the VIN is encrypted month and year. The release day is not indicated in any of the symbols. This information may only be in factory documents (for example, build sheet for American cars).

Why do decoders show different years for the same VIN?

This is due to:

  • 🔹 Using different algorithms (for example, for cars before 2010);
  • 🔹 Errors in databases (especially in little-known decoders);
  • 🔹 Confusion between model year and actual year of manufacture.

It is recommended to use the official services of the manufacturer.

How to check VIN for authenticity?

Signs of a fake VIN:

  • 🚨 Symbols I, O, Q (they are never used);
  • 🚨 Mismatch of font or depth of application on the body;
  • 🚨 Lack of code in the traffic police database or from the manufacturer.

To check use traffic police service or NHTSA (for American cars).

Is it possible to find out the country of assembly by VIN?

Yes, the first 3 characters of the VIN (WMI) indicate the manufacturer and country. For example:

  • 🔹 JT — Toyota (Japan);
  • 🔹 WDB — Mercedes-Benz (Germany);
  • 🔹 1F — Ford (USA);
  • 🔹 XTA — Hyundai (South Korea).

A complete list of WMI codes can be found on the website NHTSA.

What to do if the PTS shows a year later than the VIN?

It could be:

  • 📅 Model year (the car was released at the end of 2022, but is sold as a 2023 model);
  • 📝 Error when completing documents (needs to be corrected through the traffic police);
  • 🚨 Fraud (if the difference is more than 1 year, an examination is required).

To clarify, request a car history via CarVertical or contact your dealer.
