A free tool that looks up the ISRC of any song on Spotify, or the UPC of any album, from a Spotify link.
How to use it
Head to submithub.com/isrc-finder and paste a Spotify track or album link. You don't need an account. Guests get 2 free lookups a day; sign in for 10 a day, or 100 a day with SubmitHub Plus. Re-checking something you already looked up that day doesn't count.
For a track you'll see the artist, song, ISRC, album, UPC, label and release date. For an album you'll see every track with its ISRC.
ISRC vs UPC
An ISRC identifies one recording. Every version of a song, from the album cut to a remix or radio edit, gets its own. A UPC identifies the release as a whole, so a ten-track album has one UPC and ten ISRCs. Streaming services and collection societies use these codes to track plays and pay royalties, and you'll need them when registering with a PRO or filing a copyright claim.
Your distributor also lists both in your release dashboard, and they appear on your royalty statements.
