The {{CountryAbbr}} template attempts to generate the ISO 3166-1 alpha-2 or ISO 3166-2 code for a named country or geographic region, for use in the region: parameter of {{Coord}}. It attempts a ISO 3166-2 region code for locations in Canada, France, Germany, India, and the United States. It attempts a ISO 3166-1 alpha-2 country code for all other locations.

The first (required) argument specifies the name of the country, such as "United States" or "Chile".

The second (optional) argument is the name of a state or province within the specified country, such as "Alaska".

Attempts have been made to recognize variations commonly seen in infoboxes, such as:

  • [[Chile]]
  • [[Image:Flag of Chile.svg|25px]] [[Chile]]
  • {{CHL}}
  • {{flag|Chile}}

So far, however, the template has failed to keep up with the ingenuity of infobox creators.

Locations in Canada, India, and the United States generate invalid region codes (CA-X, IN-X, and US-X) if the second argument is omitted, blank, or invalid.

{{CountryAbbr}} can handle many inputs simply and directly. In some cases, however, it invokes a helper template:

  • {{CountryAbbr2}} - (expensive) cases where the first parameter is a template
  • {{CanAbbr2}} - provinces, territories, etc. of Canada
  • {{FraAbbr}} - departments, etc. of France
  • {{IndAbbr}} - states, etc. of India
  • {{StateAbbr}} - states, districts, etc. of the United States
  • {{ISO 3166 code}} returns the ISO code given country name and, optionally, subdivision name. For example: {{ISO 3166 code|France|Paris}} returns Lua error in package.lua at line 80: module 'Module:ISO 3166/data/FR' not found.. Covers all ISO 3166-1 and ISO 3166-2 codes.
