Is admin2_code supposed to be unique within a country? The code 640 is used for two districts (admin level 2) in India, though they are under different states (admin level 1).
This is the only case in India, but there are similar cases under CI, FM, MX, US and UY.
Is it a mistake? Do we have to check both admin1_code and admin2_code to ensure uniqueness?
