Learn about the history of Vehicle Identification Numbers and how VIN decoding works across various markets and vehicle classes.
In 1981, the 17-digit VIN was standardized by the NHTSA for vehicle destined for use in the U.S.

VIN numbers encode much of the core vehicle information, including make, engine, body and drive type, passenger restraint system, when and where they were manufactured, and the serial number. However, some of the information can vary greatly between OEMs, especially in the vehicle descriptor positions (4-8).
See detailed descriptions on what's encoded in the VIN in this blog article.
Many VIN decoder solutions provide more vehicle information than what is encoded in the VIN by tying additional vehicle details to the VDS positions. Learn more in the section "Vehicle details you should expect from a commercial VIN decoder."
For that very reason, many VIN decoding solutions specialize in certain vehicle markets. View our blog article "The Market's effect on a VIN" to learn more
What's a VIN Squish or VIN Pattern? These two terms are actually interchangeable, both describing the portion of the VIN where core information is encoded. The VIN pattern/squish is made up of positions 1-8, 10, and 11.
These are just two of the many terms centered around VINs and vehicle data. View this blog article to become a master on VIN terminology.
There is often some confusion about what information can actually be obtained from a VIN number. For example, year, make and model
All commercially available VIN decoders will extract the information encoded in the VIN Pattern or VIN Squish (What's a VIN Squish?). However, the good ones will also pass along additional information that they know about the vehicle and its configuration. Some of these inputs may include the OEM Model number, package code, installed equipment and option codes. This is sometimes referred to as VIN explosion.

Decoding a VIN can return a large amount of useful information. However, there are still many vehicle details that can't be determined from a basic decode of the VIN pattern alone. There are some vehicle details that are sometimes encoded in the VIN and others that are never encoded.
Fortunately, a commercial VIN decoder such as DataOne's is able to identify many of these details not encoded in the VIN by pulling in additional data sources.

Here are some of the major challenges with the following vehicle segments:

The good news is that many of the major manufacturers will still assign a VIN compatible with the ISO VIN Standard. If you are looking to decode off-road vehicle(s) in the North American market, here are some more details in this blog article.
