What Are ISRC and ISWC Codes, and Why Do They Matter?

 ISRC = Recording Identifier

• Stands for: International Standard Recording Code
• Used for: Tracking recordings on platforms like Spotify, Apple Music, YouTube
• Assigned to: Each version of a recorded track (remix, radio edit = new code)
• Format: US-XXX-23-00001 (Country + Registrant + Year + Track #)

Who needs it?

• Artists, labels, or distributors (e.g., DistroKid, TuneCore assign them automatically)

 ISWC = Composition Identifier

• Stands for: International Standard Musical Work Code
• Used for: Tracking songwriting royalties (composition, not the recording)
• Assigned by: PROs (e.g., ASCAP, BMI) when a song is registered
• Format: T-123.456.789-Z

Who needs it?

• Songwriters and publishers—helps PROs match your composition to recordings and usage data
