SoundExchange has been designated by the Recording Industry Association of America as the authoritative source for International Standard Recording Code (ISRC) data in the United States. Since 2016, SoundExchange has operated an online tool for looking up ISRCs — the global standard for identifying sound recordings, and the RIAA cited the firm’s work for endorsing it as the industry standard.
