<onlyinclude> <!-- See [[Wikipedia talk:Featured lists]] for an explanation of this and other inclusion tags below --> '''ISO 3166-1''', is part of the [[ISO 3166]] [[standardization|standard]]. It gives a [[Country code|code]] for the names of [[country|countries]] and [[dependent territory|dependent territories]], and is published by the [[International Organization for Standardization]] (ISO).

Using numbers is useful in countries that do not use the [[Latin alphabet]]. This is identical to codes defined by the [[United Nations Statistics Division]].</onlyinclude> ISO 3166-1 is not the only standard for country codes. Many international organizations use their own country codes, where some of them closely correspond to the ISO 3166-1 codes. == Rules for inclusion == Currently, 244 countries and territories have official ISO 3166-1 codes.
