This key can be combined with
ISO3166-1:alpha3
=*
and
ISO3166-1:numeric
=*
, which are three-letter and three-digit codes assigned by the same agency. For backward compatibility,
ISO3166-1
=*
usually contains the same value as
ISO3166-1:alpha2
=*
, due to the two-letter code being the most commonly used code. See
Country code#ISO 3166-1
for more information about ISO 3166.

should only be used on the country itself. Other objects referring to a country use a different key to indicate the ISO 3166-1 alpha-2 code of said country, most commonly
country
=*
or a variation thereof.
