RIAA certification
In the United States, the Recording Industry Association of America (RIAA) award certification based on the number of albums and singles sold through retail and other ancillary markets.[1] Other countries have similar awards (see music recording certification). Certification is not automatic; for an award to be made, the record label must first request certification.[2] The audit is conducted against net shipments after returns (most often an artist's royalty statement is used), which includes albums sold directly to retailers and one-stops, direct-to-consumer sales (music clubs and mail order) and other outlets.
