MaxMind tests the accuracy of the GeoIP Databases on a periodic basis. In our recent tests, the GeoIP databases were 99.8% accurate on a country level, 90% accurate on a state level in the US, and 83% accurate for cities in the US within a 40 kilometer radius. For more details, see GeoIP City Coverage and Accuracy.
We cover all of the IPv4 space, including all publicly available IP addresses. Note that some IP addresses may not be in use or may be reserved for private networks. These addresses are not locatable. For example, the IP address 127.0.0.1 is used by each computer to refer to itself, so it cannot be located.
Please see our IPv6 Information and FAQ page.
Please see our page describing IP allocation details.
The ISP database generally contains the ISP name. However, when we are not able to obtain the ISP we include the name of the organization the IP address block was assigned to. For example, the ISP database often contains the names of universities instead of the universities' ISPs.
When only the ISP or organization name is available, both the GeoIP ISP and Organization databases return the same value. In such cases, the shared value usually represents the ISP. When both the ISP and organization names are available, the GeoIP ISP and Organization databases return the ISP and organization, respectively.
Please see our GeoIP benchmarks.
We offer a CSV file that contains all the cities in the GeoIP City database.
GeoIP Database Updates
The GeoIP Country, GeoIP Region and GeoIP City databases are updated every Tuesday. All other databases are updated on the first Tuesday of the month.
We recommend updating at least every 1-3 months, as the data changes frequently.
A cellular IP address is one assigned by a cellular carrier (Verizon, AT&T, T-Mobile, etc.), and the connection is made via the cell tower itself. These are also sometimes referred to as 3G or 4G connections. The GeoIP Netspeed database identifies cellular IP addresses. The GeoIP ISP database identifies who the carrier is.
Wi-Fi is a method of wirelessly connecting to a local area network (LAN), and is independent of any IP address that might be assigned to that LAN--a Wi-Fi connection could be made to a wireless router that is connected to a dial-up, broadband, or commercial modem, or a cellular connection (such as a "portable hotspot"). It is not possible to identify a connection that uses Wi-Fi with only the IP address.
About 50% of GeoIP City records in the United States have postal codes. About 2% of records in Australia, Canada, France, Germany, Italy, Spain, Switzerland, and the United Kingdom have postal codes. We cannot identify the postal code in some cases where we can identify the city, because cities often have multiple postal codes. We don't identify the postal code in such cases unless we are confident that the IP address is likely to be in that postal code and not one of the others in the city.
IP geolocation services are generally unable to identify the postal code for all IP addresses. Blocks of IP addresses are frequently assigned by the ISPs that operate them to users spanning multiple postal codes.
If accuracy is not a major concern, you may use one of the following solutions. With a postal code database you could lookup a US postal code using the city and state returned by the GeoIP City database. Alternatively you can use the GEO-132 binary Format (without metro and area codes) of GeoIP City, which contains postal codes for every US city-level resolution, even when we aren't confident in the accuracy of the postal code. For the CSV format, we have a location file with postal codes for every US city record.
GeoNames provides free worldwide postal code databases.
GeoIP Web Services
Search engine spiders may be crawling your site and depleting your GeoIP web service queries. The robots exclusion standard may help prevent search engines spiders from doing so.
You can write code to check the User-Agent header for the client to see if it's a spider.
If you implemented the robots exclusion standard and still are seeing queries being used up faster than expected, we recommend logging each request to our web service in order to better understand what is causing your code to make a web service request.
We will send a warning email when your remaining queries for a GeoIP web service falls below 10,000.
It depends on your needs. There are three main considerations.
Our web service has had very good uptime - 99.97% since October of 2002 - and responds quickly, but with a local copy of the database you are not dependent on the availability of our servers or a specific network route. Also, you can perform many more queries per second with a local database.
You need to download GeoIP databases yourself in order to have access to the latest and most accurate GeoIP data. With the web service, MaxMind maintains these databases on our servers. You always receive the latest data available.
Once you have purchased a license to a downloadable database, there is no limit on the number of queries you can perform on that database. Based on the number of queries you are doing per month, you may find that either the downloadable databases or the web services are less expensive.
I would like to use a GeoIP database on xyz.com, xyz.ca, and xyz.biz. Do I need more than one site license?
As long as you own, operate, and have sole access to those websites, you only need one site license.
We are a hosting provider and have a license to one of your GeoIP databases. Can we install it on the different servers that we provide to our hosting clients?
No. While you can install the databases on multiple servers, they can only be used for internal business purposes. Any company that has access to GeoIP data and databases must have their own license.
I would like to use the GeoIP data to power a web log/analytics service that I provide to my clients. Is this allowed with just one site license?
Only one site license is needed if the GeoIP data resides on your servers and one of the following two conditions is met:
2) GeoIP data is provided in aggregate, where the IP address is not presented with the associated GeoIP data.
You can use a GeoIP Web Service to offer this service.
Using the downloaded GeoIP database to offer this service is not permitted under the license agreement.
MaxMind's minFraud service is effective in detecting stolen card fraud. MaxMind's service does not protect against "friendly" chargebacks where the cardholder placed the order but later denies having placed the order and requests a chargeback.
By reporting fraud to us, you help us to improve our service.
You cannot change how MaxMind calculates the riskScore. However, our minfraud service returns many other data points besides the riskScore. You can implement custom rules based on this data in your own code.
If you report chargebacks to us, we use that information to improve the riskScore.
Changing your blocked country list will affect the riskScores you observe when you see orders from countries you designate as high risk.
First, if you are still using minFraud version 1.0, we recommend upgrading to the latest version of the minFraud service. Upgrading from version 1.0 gives you access to the riskScore, which represents the likelihood that a given transaction is fraudulent.
Second, we recommend you use the
riskScore rather than the
as you make decisions about whether to accept, reject, or review
riskScore is based on sophisticated statistical modelling and real-time data feeds while the
score uses a simple formula. As such, the
riskScore better indicates whether a given order is fraudulent.
Third, the more input fields you pass to the minFraud service, the more accurate the
riskScore will be. In particular, we recommend passing at least the
Fourth, you can help us improve the
riskScore by reporting fraud and chargebacks to us.
You can use both standard and premium minFraud queries if you subscribe to both services.
You can use requested_type to specify whether you would like to use the standard or premium minFraud service.
Most clients use the standard service. The premium service provides more information about the credit card's issuing bank and whether the card is a prepaid or gift card. For more details, see our minFraud Feature Comparison page.
Yes. The minFraud service can detect fraud from any country.
Yes, you can use the same minFraud account to screen orders from multiple sites. You can use shopID to specify which website the orders are from.
A minFraud Alert is a notification that a previously scored transaction may be higher risk. These alerts are sent as web requests to a URI that you specify. You can set the URI we make a request to for alerts. You will also receive an email for all alerts.
We have confirmed with Visa that the minFraud service is not required to be PCI compliant, since it doesn't receive the complete 16-digit credit card number. However, we still take data security very seriously.
Yes, unused queries carry over and do not expire.
No. While the minFraud service can be used to identify fraudulent transactions, the decision whether to accept or reject a given transaction is the responsibility of the client.
Can you identify whether the person placing the order lives at the given address (or uses the given credit card or phone number)?
The minFraud service does not collect personally identifiable information such as the cardholder name, street address, or full credit card number. Thus, we cannot perform address verifications.
Not at this time. We hope to have gibberish detection in the future.
