How $country_code is auto-filled by mixpanel?

Mixpanel automatically populates the `$country_code` property for both events and user profiles based on geolocation data derived from the IP address of the request. Here’s how it works: 1. For events, Mixpanel uses the property `mp_country_code`, while for user profiles, it uses `$country_code`. 2. When an event is tracked or a profile is updated, Mixpanel extracts the IP address from the request. 3. The IP address is then cross-referenced against MaxMind’s GeoIP database to estimate the country. 4. Mixpanel sets the country code as a 2-letter country code in the raw data. 5. In the Mixpanel UI, this 2-letter code is parsed and displayed as the full country name. It’s important to note that: - The IP address itself is not stored by Mixpanel and is discarded after geolocation data is derived. - For user profiles, geolocation properties are only updated when you send or update at least one property yourself. - You can manually set or override these properties if needed.
