This guideline provides guidance about the suitability of charts for inclusion in Wikipedia articles, both in article prose and in the standard tables of charts. It does not provide specifics of formatting tables, which is the subject of Manual of Style (record charts).

Suitable charts
A chart is normally considered suitable for inclusion if it meets both of the following characteristics:
 * 1) It is published by a recognized reliable source. This includes any IFPI affiliate, Billboard magazine, or any organization with the support of Nielsen SoundScan. Recognized national measurement firms, such as Crowley Broadcast Analysis for Brazil or Monitor Latino for Mexico, are legitimate sources of charts.
 * 2) It covers sales or broadcast outlets from multiple sources.

Single-vendor/single-network charts
Charts which rank material from a single vendor or network are generally unsuitable for inclusion in articles. They should never be placed in discography tables or tables of charts. They may occasionally be mentioned in article prose if special circumstances warrant it. "Special circumstances" includes notable controversies alleging chart manipulation, or cases where eligibility requirements prevented standard charts from recognizing the sales. This would include, for example, the noted resurgence of Michael Jackson related sales at the time of his death, when many chart rules prevented any of his album sales from being credited towards a chart position. Similarly, some charts representing the home country of the artist or composer (this can mean country of origin, country of residence, official nationality or any country where the artist or composer has lived for a substantial part of their lives) or releases with a strong link to the country in question (e.g. Eurovision entries), can be included if no other suitable charts can be located.

Dependent ("component") charts
Charts are frequently related to one another mathematically. For example, the Billboard Hot 100 is derived by weighting positions on the Billboard Hot 100 Airplay and the Billboard Hot 100 Sales charts. This means that in the vast majority of cases, any song that charts on the Billboard Hot 100 can be presumed to have charted on both other charts, and specifically mentioning the position will simply clutter an article. In unusual cases, the subordinate chart can be mentioned: take, for example, a single which had no airplay because of objectionable content, but still charted extremely high on the composite chart due to sales. This would be unusual enough to potentially warrant mention.

Certifications
Certifications should be sourced directly to certifying agencies, most of which provide a searchable database. When such a database is not available, other reliable sources may be used, but they must directly state that the certifying agency has granted the certification. Many popular press articles will contain statements such as "... has gone gold ..." or "... has gone platinum ..." based on a sales figure, when, in fact, the certifying agency has not yet verified those sales and granted a certification.

Chart trajectories
A song/album's chart trajectory should not be included in an article as this constitutes an indiscriminate collection of information. Chart trajectories may be mentioned in the article text when there is sufficient reason to do so (for example, a song debuted at number 100, became a sleeper hit and peaked at number 1). Key facts, some examples being the debut position, number of weeks spent at peak position, and/or number of weeks in total on the chart may be mentioned within the article text, but should not be included as routine data for all charts.

Recommended charts
The following charts are recommended for use, although some archives of these charts are specifically deprecated. These are charts which are believed to meet all requirements for inclusion, and have reliable, licensed archives of positions which allow for stable and reliable referencing.

Many reliable charts are not included on this list, primarily due to archiving problems. The Romanian Top 100, for example, appears to be a reliable chart, but no stable searchable archive is available. These charts can be included so long as care is taken in providing a reliable source for the information.
