vin-decoder-dart

A VIN decoding, validation, and generation library for Dart.

vin_decoder provides a simple decoding and validation library for Vehicle Identification Numbers (VINs) based on ISO 3779:2009 and World Manufacturer Identifiers (WMIs) based on ISO 3780:2009. It further supports generation of synthetic VINs derived from valid WMIs.

The decoder can be used standalone in an offline mode (the default behaviour, as per earlier versions of the API), or can be further enriched by querying additional VIN information from the NHTSA Vehicle API, such as the precise make, model, and vehicle type in extended mode. Note that synthetic VINs will fail lookup in the NHTSA API, and should only be used for experimentation.

Usage

A simple usage example:

import 'package:vin_decoder/vin_decoder.dart';

void main() async {
  var vin = VIN(number: 'WP0ZZZ99ZTS392124', extended: true);

  print('WMI: ${vin.wmi}');
  print('VDS: ${vin.vds}');
  print('VIS: ${vin.vis}');

  print("Model year is " + vin.modelYear());
  print("Serial number is " + vin.serialNumber());
  print("Assembly plant is " + vin.assemblyPlant());
  print("Manufacturer is " + vin.getManufacturer());
  print("Year is " + vin.getYear().toString());
  print("Region is " + vin.getRegion());
  print("VIN string is " + vin.toString());

  // The following calls are to the NHTSA DB, and are carried out asynchronously
  var make = await vin.getMakeAsync();
  print("Make is ${make}");

  var model = await vin.getModelAsync();
  print("Model is ${model}");

  var type = await vin.getVehicleTypeAsync();
  print("Type is ${type}");

  var generated = VINGenerator().generate();
  print('Randomly Generated VIN is ${generated}');
}

which produces the following:

WMI: WP0
VDS: ZZZ99Z
VIS: TS392124
Model year is T
Serial number is 92124
Assembly plant is S
Manufacturer is Porsche
Year is 1996
Region is EU
VIN string is WP0ZZZ99ZTS392124
Make is Porsche
Model is 911
Type is Passenger Car
Randomly Generated VIN is NM4BW3NK0WA418856
