The Challenge: Trust and Fraud Prevention
Mobile phone numbers have long become a part of our identity. At the same time, many online and mobile services deliver one-time passwords over SMS for account registration or two-factor authentication. This has created significant opportunities for fraudsters to exploit insufficiently secured services for their own gain.
A common scenario occurs when fraudsters create online accounts using inactive phone numbers. If the registration process doesn’t confirm the validity of the phone number, fraudsters can then automate the account creation. These fake accounts can be used afterward for spam or other illegal activities.
The netnumber Global Data Services NumeriCheck Solution
The netnumber Global Data Services NumeriCheck service brings in real-time phone number intelligence to help prevent such fraud. NumeriCheck determines if a phone number is assigned to a mobile subscriber, allowing financial institutions and all types of service providers (OTTs, social networks, mobile/online services, etc.) to enhance their user verification screening. This mitigates, and in some cases eliminates, the damage that can be caused by those attempting to create fake accounts using invalid numbers. NumeriCheck allows for existing user data to be scrubbed regularly, and users with inactive phone numbers can be prompted to update their accounts to keep them secure.
With NumeriCheck, brands, enterprises, and communications service providers can look up MSISDNs via query services, and netnumber’s servers respond within a second with a respective number status. Phone numbers are flagged inactive when they are either mis-formatted (e.g., wrong length or invalid prefix) or are not assigned to a subscriber by the operator. The error codes give details on why MSISDNs are not legitimate. With this insight, users are better equipped to intelligently combat fraud and build trust in the mobile ecosystem. Within the context of SMS and voice traffic, this ability to detect inactive phone numbers ensures providers can effectively avoid terminating traffic to these destinations, reducing the costs associated with delivering communications to invalid numbers.
Contact centers and marketers can also benefit from accurate phone number information. By not dialing out to invalid numbers, they are able to use the agents’ time more effectively and save money on marketing costs by not paying for SMS or calls which will not get through. In addition, mobile phone number intelligence can help enhance TCPA compliance.
NumeriCheck helps customers enhance their user verification screening.
Key Features
Real-Time Data
The Mobile Number Information API returns phone number data in less than one second for most countries. This makes it possible to integrate the service in existing flows such as user account registration.
Risk Scoring
The activity status of a phone number can be incorporated into risk scoring metrics and therefore bring in another signal in order to determine the likelihood of fraud.
Normalized Routing ID
MNI normalizes the data in each country and returns it in a common format, identifying each operator by its unique NNID.
Use Cases
User Account Verification
netnumber Global Data Services enables customers to strengthen their account verification upon new user registration. A customer prompts a new user to provide their phone number and then queries the NumeriCheck platform with the phone number as a parameter. The answer is sent in real-time by netnumber Global Data Services and includes a flag that indicates if the phone number is active or inactive. In the case of an inactive phone number, the customer can adapt the registration workflow by prompting the user to check the phone number format or by adding a CAPTCHA step for authentication.
Traffic Routing
Service Providers can save some of the cost of terminating SMS or voice calls by checking if the receiving phone numbers are active or not. Routing messaging or voice traffic to such numbers can be avoided, and the corresponding termination cost can be saved.
Fraud Prevention
Risk scoring of telephone numbers is essential for fraud prevention purposes. Different data points give useful information about the risk associated with certain actions, for example, a service sign-up attempt or a financial transaction. With NumeriCheck, fraud prevention algorithms can then attach a higher risk to inactive numbers.
