Get an user country or trend_location (not authenticating user)


Hello, for a proper customer service I need to know in which country is the user who is mentioning me in his tweets. Language is not enough as Spanish and English could be from a great variety of countries, also, location field seems to be a free text where the user can type anything.

Is there any other way, apart from tweet geo or place information (which might not be enabled) where I can get user country or trend_location? I don’t have this user’s acces token, so I can’t use GET account/settings.

Thank you
