A complete version of the documentation for this template is provided at Template:Citation needed. If you are new to editing and instead just need a general overview of how sources work, please visit the referencing for beginners help page.

The {{Citation needed}} template aims to promote accountable discourse.
To ensure that all Wikipedia content is verifiable​, anyone may question an uncited claim. If your work has been tagged, please provide a reliable source for the statement, and discuss if needed.
You can add a citation by selecting from the drop-down
menu at the top of the editing box. In markup, you can add a citation manually using ref tags. There are also more elaborate ways to cite sources.
In wiki markup, you can question an uncited claim by inserting a simple
{{Citation needed}}
tag, or a more comprehensive
{{Citation needed|reason=​Your explanation here​|date=May 2021}}
. Alternatively,
{{fact}}
and
{{cn}}
will produce the same result. These all display as:
Example: 87% of statistics are made up on the spot.​[​citation needed]

When to use this tag
A "citation needed" tag is a request for another editor to verify a statement​: a form of communication between members of a collaborative editing community. It is never, in itself, an "improvement" of an article. Though readers may be alerted by a "citation needed" that a particular statement is not supported, many readers don't fully understand the community's processes. Not all tags get addressed in a timely manner, staying in place for months or years, forming an ever growing Wikipedia backlog​—this itself can be a problem. Best practice recommends the following:
When not to use this tag
Before adding a tag, at least consider the following alternatives, one of which may prove much more constructive:

How to help reduce the backlog
Currently, there are over 426,511 articles with "Citation needed" statements. You can browse the whole list of these articles at Category:All articles with unsourced statements​.
Frequently the authors of statements do not return to Wikipedia to support the statement with citations, so other Wikipedia editors have to do work checking those statements. With 426,511 statements that need WP:Verification​, sometimes it's hard to choose which article to work on. The tool Citation Hunt makes that easier by suggesting random articles, which you can sort by topical category membership.
