GeoIP2 and GeoLite2 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 September 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.
* In this month's update, a large number of geoname IDs have been updated for Brazil.
Improved confidence factor scores
August 16, 2024On September 3, 2024, we will be releasing a significant improvement to our geolocation confidence factors. This improvement will impact around 30% of the networks in the GeoIP Insights web service and the GeoIP Enterprise database.
Increase in geolocation database sizes
August 13, 2024Our IP geolocation databases released on Tuesday, August 13, 2024 will be significantly larger than our last release.
This increase in size is due to a new data source providing improved geolocation resolution for a large number of networks in Germany and Finland.
The following databases will be affected:
- GeoIP City database
- GeoIP Enterprise database
- GeoLite City database
Off-schedule release for the GeoIP City, GeoIP Country, and GeoIP Enterprise databases
August 12, 2024Today, we are issuing an off-schedule release of the following GeoIP databases:
- GeoIP City database
- GeoIP Country database
- GeoIP Enterprise database
We are correcting country-level information for a small number of networks associated with Microsoft Teams.
Updated postal codes for some cities in Portugal
August 12, 2024We are updating postal code data for the following major cities in Portugal:
Amadora
Portoand
Vila Nova De Gaia
When an IP address is geolocated to any of these cities, the last three digits
of the postal code will be set to 001
. This change will be implemented over
time, with some networks being updated starting on Tuesday, August 13, 2024, and
more networks to follow.
The last three digits of postal codes are used in larger cities to provide
geolocation information that is more specific than our underlying data allows
for, so these digits will be set to 001
. In more rural areas, the last three
digits will be maintained.
The changes will be reflected in the following products and services:
- GeoIP Enterprise database
- GeoIP City database
- GeoIP Insights web service
- GeoIP City Plus web service
- minFraud Insights web service
- minFraud Factors web service
- GeoLite City database
- GeoLite City web service

Upcoming changes to ISP names
June 27, 2024We are updating several ISP names in our data. We expect to release these changes in new database updates and web service requests beginning Friday, July 12, 2024.
There are two kinds of changes to expect.
First, we will update several popular ISP names to match their current naming and branding conventions:
Current ISP name in MaxMind data | Updated ISP name in MaxMind data |
---|---|
Korea Telecom | KT |
Telecom Italia | TIM |
Telecom Italia Mobile | TIM Mobile |
SaudiNet | stc Saudi |
Lg Powercomm | LG Uplus |
Versatel Deutschland | 1&1 Versatel |
Telefonica O2 UK | O2 UK |
INDOSAT Internet Network Provider | Indosat |
Telefonica del Peru | Movistar Peru |
TDC Danmark | TDC Net |
T-mobile Polska | T-Mobile Polska |
Atlantic Broadband | Breezeline |
Vodafone New Zealand | One NZ |
Second, we will be updating the ISP name for a number of AT&T networks. About
1,000 (0.003%) AT&T networks in the United States will have an updated ISP name,
either AT&T Internet
or AT&T Wireless
.
Updated AT&T networks will have corresponding updates to their connection_type
value as well. For most networks, this will mean:
Updated ISP name | Updated connection type |
---|---|
AT&T Internet | Cable/DSL |
AT&T Wireless | Cellular |
Please note that some AT&T networks may not have the corresponding connection type, because connection type values are dependent on additional signals.
These changes will be reflected in the following products and services:
- GeoIP Insights web service
- GeoIP City Plus web service
- GeoIP ISP database
- GeoIP Connection Type database
- GeoIP Enterprise database
Change to GeoLite2 ASN update schedule
June 18, 2024The GeoLite2 ASN database will now be updated on a daily cadence instead of every Tuesday and Friday.

Upcoming changes to our TLS certificates may impact customers with unusual server configuration
April 8, 2024Starting in May, Let's Encrypt will no longer use a cross-signed root
certificate, and the primary TLS certificate handling the *.maxmind.com
domains will be impacted by this change.
Most customers will see no impact from this change.
This change should only be of concern if the servers interacting with MaxMind domains are running a very old or out of date operating system, or if you manage your own local Certificate Authority store.

API policies are now permanently enforced
March 13, 2024To improve our server infrastructure and allow for better performance and efficiency, our API policies are now being permanently enforced as of March 13, 2024.
What are the policies?
- MaxMind only accepts API and database download requests sent with the more secure HTTPS protocol.
- MaxMind only accepts API and database download requests that are sent to the appropriate hostname as documented in the integration instructions on our Developer Portal (see direct links below).
What do I need to do? If you download GeoIP or GeoLite databases and you use
an up to date version of
our geoipupdate
program, you
do not need to take any action.
If you are using web services, or if you do direct downloads of GeoIP or GeoLite databases, you should ensure that you are using the correct hostname for your API requests, and that you are using HTTPS. Failure to do so will result in web service or database download requests failing.
You can view the appropriate URIs for GeoIP and GeoLite services and downloads on our Developer Portal using the links below:
- GeoIP Country, City Plus, and Insights web services
- GeoIP and GeoLite database downloads
- GeoIP Legacy web services
- GeoLite web services
Please note: This enforcement also affects minFraud API requests. If you are also a minFraud user, see our minFraud release note on this issue.
No GeoNames Monthly Diff Report for February 2024
February 13, 2024Due to irregularities in the latest GeoNames data, we will be maintaining the location names and codes from January. See the Monthly Diff Report for January 2024.
When the irregularities in the GeoNames data are resolved, we will update the data and post a new Diff Report.
API policies - temporary enforcement on February 7, 2024
January 25, 2024To improve our server infrastructure and allow for better performance and efficiency, MaxMind will begin enforcing our policies around our API and database download requests March 13, 2024. To help customers get ready for this change, we will have a planned, temporary enforcement of these policies on February 7, 2024.
What are the policies?
- MaxMind will only accept API and database download requests sent with the more secure HTTPS protocol.
- MaxMind will only accept API and database download requests that are sent to the appropriate hostname as documented in the integration instructions on our Developer Portal (see direct links below).
What do I need to do? If you download GeoIP or GeoLite databases and you use
an up to date version of
our geoipupdate
program, you
do not need to take any action.
If you are using web services, or if you do direct downloads of GeoIP or GeoLite databases, you should ensure that you are using the correct hostname for your API requests, and that you are using HTTPS, prior to February 7, 2024.
If you have not made the requested changes before Wednesday, February 7, 2024, you might experience a period where web service or database download requests fail.
You can view the appropriate URIs for GeoIP and GeoLite services and downloads on our Developer Portal using the links below:
- GeoIP Country, City Plus, and Insights web services
- GeoIP and GeoLite database downloads
- GeoIP Legacy web services
- GeoLite web services
Please note: This enforcement will also affect minFraud API requests. If you are also a minFraud user, see our minFraud release note on this issue..
Presigned URLs for database downloads
January 17, 2024We will begin using R2 presigned URLs for all database downloads in order to increase the security and reliability of our services. Database download links and integration methods will not be changing.
What do I need to do?
MaxMind users who download databases should make sure that their HTTP client follows redirects and there are no proxy or firewall settings that would block requests to the host we are redirecting to. We will redirect requests using HTTPS on the following hostname:
mm-prod-geoip-databases.a2649acb697e2c09b632799562c076f2.r2.cloudflarestorage.com
If you use a direct-download method (most CSV downloaders):
The permalinks for downloading databases will not be changing. You will be redirected from those permalinks to the R2 presigned URLs.
If you use geoipupdate
(most MMDB downloaders):
We will be releasing a new major version that uses redirecting links. You can test your server configuration by updating to this new major version in a controlled environment before updating your version on production.
If you download directly from the account portal:
Check your firewall and browser security settings if you get errors when trying to download.
If you need more help:
Review our documentation on how to update and download databases.
Anycast flag available for CSV format databases
January 17, 2024The Anycast data point is now available in all CVS format databases—and, as announced in a prior release note, it’s also available in all GeoIP web services and all MMDB format databases.
In most cases, the addition of a new field to CSV databases should be a non-breaking change, but we recommend checking your integration to make sure that it can accommodate the addition of new fields.
The field is present in the following GeoIP databases:
- GeoIP Country database
- GeoIP City database
- GeoIP Enterprise database
GeoLite databases
The Anycast field has also been added to the CSV version of GeoLite geolocation databases, but the new field is intentionally blank. This allows the GeoIP databases to continue to be drop-in replacements for GeoLite databases, so that it's easy to upgrade.
The field is present in the following GeoLite databases:
- GeoLite Country database
- GeoLite City database
Confirming your integration allows for new data points
The new field has been added to the Blocks CSV files:
{GeoIP2,GeoLite2}-{Enterprise,City,Country}-Blocks-IPv4.csv
and
{GeoIP2,GeoLite2}-{Enterprise,City,Country}-Blocks-IPv6.csv
The new field name, is_anycast
, has been added to the right of existing fields
and the cell will either contain 1 (if the network is an Anycast network) or be
blank (if it is not). The overwhelming majority of networks are not Anycast, and
so this field will be blank in most cases.
If you're not sure whether you're using the MMDB format, the CSV format, or both, you can learn how to check your account's database download history to determine whether you are downloading CSV files.
Please use the following example CSV files to test your integration:
We have also updated our tutorials on importing GeoIP databases. Please see relevant links below:
