MaxMind periodically tests the accuracy of the data used in GeoIP2 products and services. Accuracy is calculated by checking known web user IP address and location pairs against the data within MaxMind's GeoIP2 web service as well as the GeoIP2 City and GeoLite2 City database offerings.
The tool on this page enables you to compare the accuracy of MaxMind's GeoIP2 City Plus web service with the GeoIP2 City and GeoLite2 City database offerings by country. Leaving the Country text entry field blank will result in a display of accuracy data of the GeoIP2 City Plus web service for all countries.
Please enter a country in the text box to view accuracy data for that country or leave it blank to view data for all countries. The location is considered to be correctly resolved if it falls within the selected distance of the true location of the IP address.
|Correctly Resolved||Incorrectly Resolved||Unresolved|
|GeoIP2 City Plus web service||5%||90%||5%|
- IP geolocation is more accurate for broadband IP addresses and less accurate for cellular networks.
- Due to the nature of geolocation technology and other factors beyond our control, we cannot guarantee any specific future accuracy level. Nevertheless, we expect that the GeoIP2 City database will in the future correctly identify locations at the level of accuracy indicated in the table above.
- Fewer countries are available for cellular and IPv6 IPs due to limited test data.
