iHeartRadio has no artist claim portal. There is nothing to claim.
iHeartRadio accepts artist image and bio updates by email. Send an 800x800px JPEG artist image and a short bio to [email protected], referencing your artist name exactly as it appears on iHeartRadio. If you'd rather we handle it, send the same materials to [email protected] and we'll route it.
Mapping corrections go through iHeartRadio support. Email [email protected] with the UPC, track ISRCs, and both artist page URLs, and we'll escalate.
