ISBN Converter

Until 2006, the ISBN had 10 digits including the check digit. In 2007, a revision of the ISBN standard has been introduced that is compatible with the EAN (European Article Number) standard.For that reason, the number of digits has been increased to 13 digits. However, each ISBN10 has a corresponding ISBN13 which can be calculated by our ISBN Converter.

To convert an ISBN10 to ISBN13, please enter a valid ISBN10 and press the "convert" button.
