Verify IP Addresses and Geolocate Visitors To Prevent Fraud

DOTS IP Address Validation

Mismatches between customers' device location and their physical address is a leading indicator of online fraud.

For example, if a customer is determined to be in Croatia, and the customer inputs a California home address, this likely indicates fraud. DOTS IP Address ValidationSM is a real-time web service API that identifies the location of an IP address from any location in the world. Global coverage includes Africa, Asia, Australia, Europe, North America and South America. By utilizing this service, companies can cross-reference the location of a visitor's IP address against other data points, including billing and shipping addresses, to prevent possible fraudulent transactions.

  • Our IP validation API is an important tool in the fight against online fraud. Using reverse IP lookup, this API helps you identify location mismatches and open proxies, protecting your company from suspicious activities. If an IP address geolocation doesn't match the customer's entered address, the transaction could be fraudulent. By using IP validation and receiving real-time results, you can evaluate risks based on the customer's actual location. IP verification can be used at the point of application or registration to provide you with real-time fraud prevention. Wouldn't you want an immediate heads-up when someone attempts to hide their true location or identity? IP address geolocation alerts you immediately, allowing you to abort a transaction before harm can be done.
