Usage

This template is intended to be used when a statement is sourced but it is questionable whether the source used is reliable for supporting the statement. It produces a superscripted notation like the following:

It was actually written by Francis Bacon.^[9]^{[unreliable source?]}

Articles tagged with this template will be categorized into Category:All articles lacking reliable references.

Place this template inline, {{Unreliable source?|date=December 2025}} following the questionable source. The template should be placed outside and immediately after the reference to the questionable source (<ref> ... </ref>), within the article's text:

Potentially controversial statement.<ref>some alleged source for this</ref>{{Unreliable source?|date=December 2025}} Next sentence.

Parameters

The template has the following optional parameters:

date: should be set to the month and year when the article was tagged. Example: {{Unreliable source?|date=December 2025}}
reason: a note explaining why you think the source is unreliable as per WP:RS. Displays as a tool tip. Keep it short (one sentence) as longer material belongs on the talk page. It is good to reiterate the reason in your edit summary. Example: {{Unreliable source?|reason=Your WP:RS-based reason here.|date=December 2025}}
sure or certain: if set to "y" or "yes" will remove the question mark from the template's output to denote a degree of certainty that the source is unreliable. Please use this with a |reason= parameter, and only after a good faith attempt to verify the reliability of the source in question. Example: {{Unreliable source?|sure=y|reason=Your WP:RS-based reason here.|date=December 2025}} NOTE: This parameter has an alias, |failed=, which may make more grammatical sense when used with certain redirects like {{verify credibility}}.

When to use and not use this template

This template should be used to express your doubt about the credibility of a source.

This tag should not be used on unreliably sourced contentious statements about living persons; if a source for such a statement is not reliable, the statement and the source should be removed immediately.

For whole articles or article sections that rely on suspect sources, considering using the banner template {{More citations needed}} or {{More citations needed section}}, respectively, rather than individually tagging a large number of statements.

For sources promoting fringe theories and pseudo-science, the more specific template {{Unreliable fringe source}} can be used. Even more specifically, flag improperly sourced medical claims with {{Unreliable medical source}}.

This tag should not be used to indicate that the sourced material could not be found within a given source. In that case, {{failed verification}} is a better template. For statements that have failed verification and have a questionable would-be source, consider removal of the source (and possibly the statement) over using both tags.
