This vehicle number identification device is provided with: a registered number information acquisition unit which acquires registered number information associated with an identification medium mounted in a vehicle; a number plate image acquisition unit which acquires an image of a number plate of the vehicle; an OCR processing unit which acquires OCR result information representing results of performing an optical character recognition process on the number plate image; an estimation processing unit which inputs the number plate image into a machine learning model and acquires estimation result information output from the machine learning model; and a match determination unit which, if it is determined that at least two of the registered number information, the OCR result information, and the estimation result information indicate the same vehicle number, identifies that vehicle number as a vehicle number of the vehicle.
