One vehicle. One permanent record.

● Reported

Information supplied by an external source — a state, an insurer, NHTSA. The source is always identified. CarKnown never implies it verified these.

Publishing shop — identity confirmed

Work recorded by the shop as it was performed and published by its platform, which confirmed the shop is the business it says it is — findings, parts, mileage, evidence. Not a judgement on the work.

Sealed

The finished record is hashed and signed when it is completed. Altering it breaks the signature, so a changed record cannot pass as the original.

How it works

01

Look up the vehicle

Enter a VIN. The vehicle is identified immediately from manufacturer data.

02

See reported history

Recalls and outside reports, each labeled with its source.

03

See verified service

Records created by the shops that did the work — sealed when the job closed.

04

Follow the record

The record belongs to the vehicle and grows with it, owner after owner.

Put your work on the vehicle's permanent record — created automatically from the work orders you already write.
