On Monday, October 1st, we will be changing a large amount of our U.S. coordinate (latitude & longitude) data* to use GeoNames coordinates for postal codes. This change will ensure greater consistency during our build processes. Around 95% of US coordinates will change with most moving about 1 mile. About 5 to 10% of US coordinates will move by more than 10 miles.
* Coordinate data is approximate and is not precise. It should not be used to identify a particular street address or household as it refers to a larger geographical area instead of a precise location.

Effective August 21st, we will be mapping IP addresses to Districts (Gu) of Seoul instead of Seoul. This will allow customers to have a more precise mapping, similar to how we map IPs to New York City and London boroughs, and Tokyo’s special wards. We will continue to map some IPs to Seoul if we are unable to determine the specific district the IP is located in. We will also continue to map IPs located in the central Jung District to Seoul, similar to how we map IPs in Manhattan to New York and IPs in Chūō to Tokyo.

Effective July 24th, we will be mapping more IP addresses to special wards of Tokyo instead of Tokyo itself. This will allow customers to have a more precise mapping, similar to how we map IPs to New York City and London boroughs. We will continue to map some IPs to Tokyo if we are unable to determine the specific special ward the IP is located in.

- Effective July 10th, we will update the ISP and Organization data to replace the Time Warner Cable name with the name Spectrum, as these two ISPs have merged and Time Warner Cable has been rebranded as Spectrum.

We completed our most recent review and update of Geolocation for Crimea. Our accuracy has increased as follows:
Approximately 89% of website visitors who are from Crimea are currently located by GeoIP as being in Crimea. Approximately 97% of the visitors who are located in Crimea by GeoIP are actually in Crimea.
We currently locate Crimea in Ukraine, as we use GeoNames data and they locate Crimea in Ukraine. If GeoNames locates Crimea in Russia in the future, we will follow their change and post an announcement here as well as on https://twitter.com/maxmind.
In legacy GeoIP, we return a FIPS region code of 11 or 20. In GeoIP2, we return a iso code of 40 or 43 in the subdivision object.
Due to the nature of geolocation technology and other factors beyond our control, we cannot guarantee any specific future accuracy level. Further, accuracy figures are subject to change as IP networks are reallocated.

- Our Account Portal has been updated to include the ability for our customers to create and manage multiple license keys.

- Our GeoLite2 ASN database is now provided in a CSV format suitable for importing into a SQL database as well as a GeoLite2 ASN database in our MaxMind DB binary format. You can download the database here. GeoLite2 databases may also be downloaded and updated with our GeoIP Update program.

- We’ve updated the ISP and Organization data to replace the Charter Communications and Bright House Networks data points with the data point Spectrum, as these two ISPs have merged and been rebranded as Spectrum.
- March 5, 2017
The GeoIP databases and services providing ISP and Organization data have been updated. The change is to a number of European and Latin Americans ISPs. We’ve updated the ISP name to use the common trade name instead of the legal name. This will make it easier to recognize the ISP.
Please note that if you use this data point, for example, to flag a visitor if they change ISP, you may need to adjust your implementation in order to avoid false positive flags.
The ISP name changes include the following:
Telefonica Movil De Chile S.A.to
Movistar Movil Chile
- November 8, 2016
We’ve updated any GeoIP database or service providing ISP and Organization data to return Comcast Business rather than Comcast Business Communications. We are doing so in order to use the trade name of the ISP and also because it is shorter.
Please note that if you use this data point, for example, to flag a visitor if they change ISP, you may need to adjust your implementation in order to avoid false positive or negative flags.
The following GeoIP databases and services are affected by this change:
- GeoIP2 ISP database
- GeoIP2 Enterprise database (Update will apply to November 15th release)
- GeoIP Legacy ISP and Organization databases
- GeoIP2 Precision and Legacy City Service
- GeoIP2 Precision and Legacy Insights Service
- September 15, 2016
- The GeoIP City databases now provide significantly improved accuracy for countries outside the US, especially China, India, and Japan. See more information about GeoIP accuracy on https://www.maxmind.com/en/geoip2-city-database-accuracy
- April 26, 2016
MaxMind will be adding accuracy radius to the GeoLite2 City and GeoIP2 City databases as well as the GeoIP2 Precision City service.
The Accuracy Radius is an indication in kilometers of geolocation accuracy for the latitude and longitude coordinates we return for an IP address. The actual location of the IP address is likely within the area defined by this radius and the latitude and longitude coordinates.
As a reminder, the latitude and longitude coordinates we return for a given IP address are near either the population or geographic center of the most granular location data we return for that IP address (i.e., country, region/state, city, or postal code) and should not be used to identify a particular address or household.
For the binary databases and web service, this field will be available at
/location/accuracy_radius. All official GeoIP2 client APIs already support this field.
For the CSV databases, a new
accuracy_radiuscolumn will be added to the end of the IPv4 and IPv6 blocks files. Please test your integration to ensure compatibility before updating. You may test your integration by downloading the latest copy of the GeoLite2 CSV database, which already has the accuracy_radius column appended.
Target availability dates:
- GeoLite2 City – May 3, 2016
- GeoIP2 City – May 17, 2016
- GeoIP2 Precision City – May 19, 2016
- April 11, 2016
- We are changing the latitude and longitude for two locations in our GeoIP and GeoLite databases. For IPs in the United States that we are unable to locate to a particular state or city, we will return 37.751, -97.822. For IPs that resolve to Ashburn, Virginia with zip code 20147, we will return 39.018, -77.539. We would like to remind customers that latitude and longitude values contained in the GeoIP databases are not precise and should not be used to identify a particular address or household.
