GeoIP Release Notes

GeoNames monthly diff report (January 2026)

GeoIP and GeoLite databases incorporate GeoNames geographical data, which is made available under the Creative Commons Attribution 4.0 License.

Monthly updates to GeoNames data are incorporated into our databases as we refresh them. Above you will find a CSV report of these changes as they apply to English place names for the month of January as they relate to the following fields:

• 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:

• Argentina
• Australia
• Germany
• France
• Japan
• Poland
• Spain
• Turkey

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

• Finland
• Switzerland

This change is to reduce false positives when the end users of a network are dispersed all over the subdivision or country.

The update will be reflected in the following products and services:

• GeoIP City database
• GeoIP Enterprise database
• GeoIP City Plus web service
• GeoIP Insights web service
• minFraud Factors web service
