A method, system and computer program product for increasing automation of license plate reading accuracy, can involve searching by a correlation search process, ALPR (Automatic License Plate Recognition) results against an ALPR database of previous ALPR results, when an ALPR read by an ALPR search engine occurs with respect to a license plate, and constructing a confidence level for a correlation to a known previous license plate read based on a number of parameters and a number of times that the parameters match, when a match is found in the ALPR database for a parameter contained in the ALPR database as a result of the correlation search process.
