This template is used to tag articles which satisfy the following three criteria:
- The subject is non-fictional.
- It is associated with a fixed location on Earth.
- The article lacks geographic coordinates (latitude and longitude) because the subject's location is disputed or unknown.
Evidence that the subject's location is disputed or unknown might include:
- a reliable source says the subject's location is unknown AND no reliable source gives a specific location for it, or
- reliable sources provide two or more contradictory locations.
If further research seems likely to uncover definite coordinates, do not apply this template; use {{Coord missing}} instead.
If the subject's location is known approximately, it may still be better to provide rough coordinates using {{Coord}} than to apply this template.
{{Coord unknown|countryname}}
- countryname:
- should be one of the country names used in the subcategories of Category:Articles missing geocoordinate data by country. Where a particular country cannot be identified, one of the continent names used in the subcategories of Category:Articles missing geocoordinate data by continent should be used instead.
- Note: this parameter is for future use. The template doesn't yet subcategorize articles by country or continent, but may begin doing so at a later date.
