A method of reading an optical code is provided that encodes a message that has a character chain having a plurality of characters, said method comprising the steps: of recording image data having the optical code; evaluating the image data by reading the message; comparing the read characters of the message with at least one scheme that contains a character for at least one position of the message that is expected at this position in codes to be read; and checking or correcting the read message based on a scheme matching the message after the comparison. A prefabricated catalog of schemes is provided here and a subset of the schemes of the catalog is activated for the comparison with the read characters of the message.
