Tire DOT Recognition
Description
Description
Each tire has a DOT (U.S. Department of Transportation) identification number printed on the sidewall. This code is made up of numbers and letters. Four blocks make up this identification number:
- a 2 to 3-character code identifying the factory that manufactured the tire,
- a 2-character dimension code specific to the manufacturer
- a manufacturing code specific to the manufacturer
- a 4-character code identifying the year and week of production.
For example, the following DOT code "DOT T7D3 1BH 3218" can be decoded as follows:
- Manufacturing plant: T7 - the list of plant codes can be found below (sourced from NHTSA)
- Size code: D3
- Manufacturer's code: 1BH
- Year and week of production: 3218 - week 32 of 2018

The DOT Recognition API transforms a photo of the DOT code on the tire sidewall into information that can be used by an information system. This API uses artificial intelligence (AI) functionalities, which transform an image into characters, and can read black characters printed on a black background.
Key features
Automated extraction of DOT code from tire sidewall image
Compatible with mobile applications for easy use
Allows photos to be submitted from a mobile application with image guidance
Benefits
Benefits
Automatic reading and decoding of a tire's DOT number automates tire maintenance processes, quality control and optimized stock management.
In fact, visually searching for the code, transferring it by hand to an IT tool or a paper file, and ensuring the quality of this transcription are tedious manual operations, with little added value and a source of error.
The benefits of automation include time savings in reading and encoding.
Reliability and the reduction of encoding errors in user applications are also significant gains.
Use Cases
Use Cases
The DOT identification number is used at various stages in the tire life cycle:
During quality controls for stock management: reading and automating the encoding and decoding of the DOT code enables optimized stock management, since it allows tires to be sorted according to their week and year of manufacture.
During tire maintenance: the automatic DOT code check integrated into the workshop tools ensures that the tire complies with the manufacturer's recommendations. This decryption also enables maintenance workshops to provide consumers with more information on the origin and age of their tires.
During tire recycling cycles: once again, relying on an automatic and reliable encoding of the DOT identification number enables tire recycling or retreading workshop managers to qualify the operations to be carried out, thus saving time in follow-up and sorting operations.

Prerequisites:
- Minimum image height should be 800 pixels
- Aspect ratio should be close to 2 (or 2.37)
- Text height should be around 15% of image height
- Orientation of image vs text should be as shown
- Avoid photo of mobile/laptop screens
For accurate results, the image of tire sidewall should be clear with the DOT code properly visible, as shown beside.
Use of the APIs
The use of all our APIs is subject to the use of a user token. To obtain this token, it is necessary to authenticate by an API call.
The authentication allows to get the user token which will be requested in all the API calls.
High Level Steps:
- When a consumer registers an app for any product, a client id and client secret is created.
- Client Id is treated as API Key and used to authenticate the consumer for subsequent API calls.
