In order for your sales to be included in the reports, they need to fulfill a few conditions. First, for each album destined for the charts you’ll need to enter a valid UPC, and for each track, an ISRC.
Additionally, SoundScan requires that albums sell for at least $3.49 USD, and that single tracks be sold for at least $0.39 USD (or the equivalent in your currency).
In order to count toward Official Charts, albums must sell for at least $3.75 GBP, and tracks for at least $0.40 GBP (or the equivalent).
ARIA Charts and NZ Music Charts do not enforce any particular minimum price, but they do require the album or track be purchased in order to be counted.
