Run by Nielsen, Soundscan is the official method of tracking sales of music and music video products throughout the United States and Canada. They have been tracking sales since March of 1991. It is a common misconception that RIAA uses the Soundscan information to track sales and certify Gold and Platinum sales etc. They do not. On the other hand, Billboard uses the Soundscan information to create their music charts. Anyone selling music, as long as it has its own UPC (barcode) or ISRC, can register their product to be tracked (and its FREE!!). You fill out the Title Addition Sheet and send it in. It may take 4 to 6 weeks to get it in the system, so send it before you release your music. If you want to get on the Billboard charts you must register with Soundscan.
