If you are uploading files, you will be offered the option of providing ISRC codes for each song. If you do not have any ISRC codes assigned yet, we'll supply them for you at no additional cost. (We assign the codes after the order has been placed)
If you prefer not to have ISRC assigned you can opt out of this by checking the box on the Audio Intellectual Property Rights (IPR) Page form you will be presented with after uploading and sequencing your tracks.
If you're looking for the ISRC codes that we've already assigned to your order - https://support.discmakers.com/hc/en-us/articles/115006451527-Can-I-see-what-ISRC-Codes-have-been-assigned-to-my-tracks-
