As you might expect, we get a lot of questions about VINs. There is a lot of confusion about what a VIN is, how it is used, what information is captured within it, and what is not. In this series, we hope to provide a good resource that you can use to educate yourself on Vehicle Identification Numbers (VINs) and VIN Decoding. The articles will progressively build from very basic and general information about VINs to more detailed and specific aspects of using them and vehicle data in business and technical settings. We hope you find them useful.
The VIN (Vehicle Identification Number) refers to the unique sequence of characters assigned to a vehicle that contains information to identify and describe each vehicle. This article covers the history of VINs and how they have evolved to their current format.
There are different VIN standards internationally, including ISO and NHTSA, that have similar sequence requirements such as a 17-character length. This article focuses on the components of a VIN created to meet the NHTSA standard for passenger and light-duty vehicles.
Almost all vehicle markets around the world follow the ISO recommendations for the standardized 17-digit VIN. However, there are still some differences in VIN standards across various markets internationally, highlighted in this article, as well as how this can impact your decision when choosing a vehicle data provider.
VIN decoding has a unique set of terminology that may not be intuitive to the average user. This article will define 25 common terms that you will likely see when working with automotive and VIN data.
Not all end-users expressing interest in a VIN data solution are familiar with what to expect, often starting at a new company/role or exploring new business applications for the data. This article outlines the top 10 things you can expect to receive when decoding US passenger or light-duty VINs.
As noted in previous articles, the VIN pattern is required to encode specific information, even more so in the US and Canadian markets. However, you will come across exceptions to even these basic rules. This article addresses a couple of these common VIN rule exceptions.
Potential customers often inquire about identifying specific vehicle details/attributes by VIN. While a fair amount of details can be determined from the VIN Pattern alone, there are some limitations to the data returned without 17-digit decoding. This article goes over vehicle details that the VIN pattern is not going capture, or capture consistently.
The NHTSA VIN standard applies to vehicles destined for use on US roads, however, they do not have jurisdiction over off-road recreational vehicles. Still, there is a need for these VINs to be decoded for sales, registration, insurance, and taxation. Can they be decoded using the same principles and VIN decoders?
While light-duty and passenger vehicles make up a large portion of VIN decoding, segments like mid-duty, heavy-duty, and motorcycles also represent significant markets with strong business opportunities, driving interest in decoding services for these vehicles. This article is a brief overview of decoding vehicles outside the light-duty and passenger segments.
For many applications, a basic VIN decoder provides all the necessary details, but advanced VIN decoders offer much more precise and detailed information. This article explains how a commercial VIN decoder can deliver greater accuracy than a basic one.
VIN decoders, VIN check tools, and vehicle history reports offer valuable data for automotive businesses, but the data they provide differs. This article clarifies the key differences between these services by detailing their core functionalities.
Getting an invalid VIN message can be frustrating, especially when the cause isn’t obvious. This article discusses the most common reasons a VIN may fail to decode and how businesses can address these challenges.
Quickly and accurately identifying vehicle specifications is essential for many businesses in the automotive and allied industries. This article highlights how businesses can retrieve detailed vehicle specs using a VIN decoding solution, the types of specifications available, and which industries benefit most from VIN-based data retrieval.
VIN Decoding 201 dives deeper into the complexities behind the 17 characters of a VIN and why not all VIN decoding solutions are created equal when it comes to obtaining a highly granular level of detail in a consumable format. We hope the articles in this series will help better inform your decision in vetting your potential vehicle data partner.
