minFraud FAQ

If you are using minFraud Legacy, you may wish to upgrade to one of our current minFraud services if possible. The current minFraud services can accept additional inputs for improved scoring, and they can also return additional outputs. A summary of what’s new can be found here.

If your integration method requires that you use minFraud Legacy, we highly recommend upgrading to the latest version of minFraud Legacy through your account, if you are not using version 1.3 already. Upgrading from version 1.0 gives you access to the riskScore, which represents the likelihood that a given transaction is fraudulent. The riskScore should be used instead of the deprecated score (no longer supported since January 1, 2014) to determine whether to accept, reject, or manually review orders. The riskScore is based on sophisticated statistical modeling and real-time data feeds to better indicate whether a given order is fraudulent; the score is based on a simple formula and should no longer be used.

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 /billing/city, /billing/postal, /billing/country, /credit_card/issuer_id_number, /email/address, /device/user_agent, and /device/accept_language fields.

We recommend you use the Device Tracking Add-on for the minFraud service on your site. The add-on helps catch fraudsters who change proxies while they are browsing your website or between visits to your website.

You can help us customize and improve the riskScore for you by reporting fraud and chargebacks (as well as false positives) to us.

In the MaxMind account portal, we provide the Custom Rules functionality to minFraud Score, minFraud Insights, and minFraud Factors customers. You can use custom rules to automate the dispositioning of transactions (accept, reject, or queue for manual review). Learn more in our Custom Rules Guide.

And, as always, you can contact our support team at support@maxmind.com with any questions pertaining to the minFraud service. We are happy to manually review your account and make specific suggestions on how to improve the performance of the service for you!

Use minFraud Score to get the bottom line; the transaction risk assessment of the riskScore and IP address risk as expressed in the IP Risk Score.

Use minFraud Insights when you need a broad range of data points to help assess risk.

Use minFraud Factors to learn more about how the riskScore was derived. Note that the Factors service requires additional permissions and is only available at an enterprise level.

The Device Tracking Add-on helps catch fraudsters who change proxies while they are browsing your website or between visits to your website.

It is optional, but recommended, and is easily implemented with some JavaScript that helps us identify the device your customer is using to determine whether it has been used in previous fraudulent transactions. The device information is factored into the proxyScore and riskScore returned through the minFraud service.

For optimal performance of the Device Tracking Add-on, please add the JavaScript to as many checkout pages as you can.


MaxMind tests the accuracy of the GeoIP2 and GeoIP Legacy Databases on a periodic basis. In our recent tests, the downloadable databases were 99.8% accurate on a country level, 90% accurate on a state level in the US, and 86% accurate for cities in the US within a 50 kilometer radius. For more details, see GeoIP2 City Coverage and Accuracy. The GeoIP2 Precision Web Services contain our most accurate data at a city/postal code level, geolocating 9% more IPs the correct postal code and 4% more IPs to the correct city in the United States than the GeoIP2 Downloadable Databases.
Search engine spiders may be crawling your site and depleting your GeoIP2 Precision 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 the GeoIP2 Precision service in order to better understand what is causing your code to make a web service request.
It depends on your needs. There are four main considerations. Our GeoIP2 Precision: City and Insights services accurately geolocate 4% more IPs to the correct city and 9% more IPs to the correct postal code in the United States than the GeoIP2 and GeoIP Legacy downloadable databases. Our GeoIP2 Precision services have had 99.99% uptime since January 2010 and respond 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 GeoIP2 databases yourself in order to have access to the latest and most accurate GeoIP2 data. With the GeoIP2 Precision services, 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 GeoIP2 Precision services are less expensive.
