Interpretation of Language and Country Codes

Kiusau · June 9, 2019, 8:34pm

QUESTION ONE: I have noticed that Matomo language codes sometimes appear as two-characters and sometimes as two character pairs separated by a hyphen. When only two characters appear, how does one determine the country. For example, does en mean the UK, US, Australia, Canada, Nigeria, New Zealand?

QUESTION ONE: What code is used to determine the country on the world map used by Matomo?

Hi,

When you haven’t set up any geolocation, Matomo falls back to the default, very naive Location detection:

It maps Languages to Countries according to this list: (and is obviously an often incorrect guess)

github.com

matomo-org/matomo/blob/3.x-dev/core/Intl/Data/Resources/languages-to-countries.php

return array(
    'bg' => 'bg', // Bulgarian  => Bulgaria

My recommendation is to setup GeoIP to get proper location results.

When two characters appear it means matomo was not able to detect country. To improve the location detection, use geoIP 2 PHP(Recomended) or geoIP 2 Apache.
For using gepIP plugin go to matomo server-> administrator -> System -> Geolocation
