• geoname_id
• country_name
• country_code
• city_name
• subdivision_1_iso_code
• subdivision_2_iso_code

Note that the values for the old_ and new_ columns for a given field only differ for the field defined in the diff_in column.

Effective tomorrow, Wednesday, January 7, 2026, we will be blanking out the city and postal fields more often for cell networks in the following countries:

We will also be blanking out the subdivision, city, and postal fields more often in:
