Unfortunately, if they reside outside of the UK, artists are required to provide their own ISRCs. However, this is a simple process and any good internet seach engine will provide a list of companies that will help. Just search <ISRC application form for (yourcountryhere)> and several links should appear. If artists are resident to the UK they should leave the ISRC field clear an RouteNote can automatically generate one for them. RouteNote will also generate UPCs for artists of all nationalities so please leave this field clear too.
