An ISRC (International Standard Recording Code) is a unique 12-character alphanumeric ‘digital fingerprint’ that stays with an individual recorded track forever, regardless of any changes in ownership of the track. The unique ISRCs for your tracks during the metadata and content stage prior to delivering your products to retailers. ISRC codes are used to trace sales of single tracks through various digital distributions and broadcast outlets.
A UPC (Universal Product Code or Barcode) represents the entire digital product (album, EP or single), as opposed to just an individual digital track. Manufacturer’s UPC codes are typically found on the back of the sound recording’s physical packaging, and are used by brick and mortar retailers and online outlets to gather and track sales information for the entire product.
