Like en_US equals English - United States. es_AR equals Spanish - Argentina.
Solution for future users:

Take a look here:

One approach is to download both text files (listed in the first paragraph), and combine the values the codes map to.
For example "en" is defined as "English" in the first file, and "US" as "United States" in the second file. These appear in separate files, because the list would be exhaustive if every combination of language+country was listed.
