BASED ON EU REGULATION
A VIN workflow built around the official EU structure
ManageVIN follows Annex II to Implementing Regulation (EU) 2021/535 for vehicle categories M, N and O. It separates WMI, VDS, the check digit and VIS so manufacturers can see the purpose of every position.

FROM STRUCTURE TO RECORD
Calculate one VIN or build a controlled production series
Use the calculator without an account. Create a free workspace when you need reusable profiles, VIN series and structured production records.
02
Calculate position 9
ManageVIN validates permitted characters and calculates the check digit using the fixed character values and position weights in Annex II.
03
Keep the production record
When signed in, save the VIN, add a reference or note, mark it as used and export the current list to Excel.
PRACTICAL GUIDE
The four functional parts
A VIN consists of WMI, VDS and VIS, with a mathematically calculated check digit in position 9.
WMI · positions 1–3
The World Manufacturer Identifier is assigned by the competent authority and identifies the manufacturer. If the manufacturer produces fewer than 500 vehicles worldwide each year, the third character is 9.
Learn moreVDS · positions 4–8
Five alphanumeric characters describe the vehicle’s general characteristics. Any unused positions must still be filled so the section remains five characters.
Learn moreCheck digit · position 9
Characters are converted to numerical values, multiplied by fixed position weights, totalled and divided by 11. A remainder of 10 produces X.
Learn moreVIS · positions 10–17
The Vehicle Indicator Section uniquely identifies the vehicle together with WMI and VDS. The last four positions must be digits.

VIN check-digit questions
Is the VIN check digit always position 9?
Under Annex II, Part 2 of Implementing Regulation (EU) 2021/535, the ninth VIN position is the mathematically calculated check digit.
Can the check digit be X?
Yes. When division by 11 leaves a remainder of 10, the check digit is X.
Does ManageVIN assign a WMI?
No. A WMI is assigned through the competent authority and the relevant international framework. ManageVIN uses the WMI you have already been assigned.
Are VINs saved automatically?
No. Guest calculations are not stored. Signed-in users save a completed VIN only when they select Save.
