Music recording sales certification is a system of certifying that a music recording has shipped or sold a certain number of copies, where the threshold quantity varies by type (such as: album, single, music video) and by nation or territory (See also: List of music recording certifications).

Almost all countries follow variations of the RIAA certification categories, which are named after precious materials. The thresholds below are used in the United States and United Kingdom only. For other countries definitions, see List of music recording certifications:

The number of sales or shipments required for these awards depends upon the population of the territory in which the recording is released. Typically, they are awarded only to international releases and are awarded individually for each country in which the album is sold. Different sales levels, some perhaps 10 times lower than others, may exist for different music media (for example: videos versus albums, singles, or downloads).

Originally applied to LP records, certification is now most commonly awarded for compact disc (CD) sales.^{[citation needed]} Certification is often awarded cumulatively, and it is possible for a single album to be certified silver, gold, and platinum in turn. An album that becomes platinum twice over is said to be "double-platinum"; three-times over, "triple-platinum", etc., which can all be generalized with the term "multi-platinum". Artists can also become multi-platinum sellers if they have at least two albums in the same territory both going single Platinum. A poor-selling record is often jokingly said to have "sold lead" (the heavy metal lead), in contrast to attaining high status as a gold or platinum album.
