Frequently Asked Questions
What is a VIN?
A Vehicle Identification Number (VIN) is a unique 17-character code assigned to every motor vehicle, encoding the manufacturer, vehicle attributes, and serial number.
What do WMI, VDS, and VIS mean?
WMI (World Manufacturer Identifier) is the first 3 characters. VDS (Vehicle Descriptor Section) is characters 4-9. VIS (Vehicle Identifier Section) is characters 10-17.
Is any data sent to a server?
No. VIN decoding runs in your browser using local lookup tables.
Does the tool validate the check digit?
Yes. The 9th character is the check digit; the tool verifies it using the NHTSA algorithm and flags invalid VINs.
