The cardback barcode is where you find the .10x number
Where
.100 = German
.101 = French
.102 = English
.103 = Italian
.104 = Not sure this has been identified yet
.105 = Spanish
Some of the .10x numbers are present as stickers over existing .10x numbers. So although the card may be in one language(s) the chip may actually speak in another language and this is where checking the .10x number comes in handy.
