The present disclosure discloses a method and device for matching a license plate number and a method and device for matching character information, and belongs to the field of an intelligent monitoring technology. The method for matching a license plate number comprises: obtaining a first license plate number to be matched; obtaining a license plate number library, wherein the license plate number library includes at least one second license plate number; calculating, based on a visual similarity of characters, a difficult degree in editing a character string required to converting between each second license plate number and the first license plate number; and determining, according to the difficult degree in editing a character string, at least one second license plate number matched with the first license plate number. The present disclosure can reasonably evaluate the similarity between the second license plate number and the first license plate number. Even if the license plate number is wrong, the license plate number identifying the same vehicle can be successfully matched, thereby ensuring the effectiveness and rationality of the monitoring function.
