ISRC codes look like this: **-***-**-*****. They are structured using dashes for easier readability. However, the dashes are NOT considered to be part of the 12-digit ISRC code. When entering your ISRC codes at an online music distribution site like Apple Music (iTunes), registering at SoundScan, or encoding your ISRCs, you should enter it as a 12-digit code without dashes or spaces. (Unless, of course, they specifically instruct you to enter it differently.)
