An ISRC (International Standard Recording Code) is a 12-character ISO 3901 identifier that uniquely tags a specific sound recording. The first two characters are the country code, the next three are the registrant (label or distributor), the next two are the year, and the last five are a unique recording number.
Is the ISRC the same as the ISWC?+
No. The ISRC identifies a specific recording, while the ISWC identifies the underlying musical composition. USAT21300935 is the ISRC for this recording; T-070056690-0 is the ISWC for the composition it is a recording of.
