Vonage Number Insight API identifies phone numbers around the world to ensure you have accurate and updated contact information and determines the best way to reach your customers.
Number Insight V2, now available in Beta, takes it a step further by providing you with real-time and accurate fraud assessment data for any global phone number. To get started, simply refer to the developer documentation.
Phone Identity Challenges
No company wants to become yet another victim of a fraud attack. It’s important to have the latest authentication and identity solutions to protect not only your company’s finance and reputation, but your customers from account takeover and SIM swap scams.
Vonage’s Number Insight V2 can help provide peace of mind by answering some of your most frequently asked questions:
- How do I know if a phone number is genuine for outbound marketing communications?
- Should I allow this phone number to sign-up for an account or perform a password reset?
- Is this phone number related to toll fraud or SIM swap?
- Which phone number should be sent through the two-factor authentication process?
Our easy-to-implement Fraud Score API assigns a score and risk recommendation to any phone number that you provide. Both the carrier and phone type (mobile, landline, VoIP, etc.) are provided, along with whether the number was reported for blocking.
The Fraud Score ranges from 0 to 100. The larger the score, the higher the risk. For each score a risk recommendation is indicated. The following highlights the risk score range and our recommended action for the assessed phone number.
0 - 45
46 - 60
61 - 100
SIM Swap Detection
SIM swap is a type of fraud that occurs when a scammer hijacks a victim’s mobile phone number. To hijack a mobile phone number, a bad actor will typically socially engineer a support agent at a mobile carrier, convincing the agent that the phone is lost, and port the victim’s phone number to a SIM card that the scammer controls. As a result, the scammer can receive the victim’s texts and phone calls.
Vonage’s solution is to take any mobile number and provide you with real-time data, directly sourced from mobile network operators, telling you if the SIM card linked to that phone number has changed in the last seven days. With a simple true/false indicator, it provides assurance that the user’s mobile number can be used for communications or authentication purposes and allows you to assess potential risk.
Fraud Score and SIM Swap Detection will be charged on a flat per phone number basis. There are no platform fees associated and the price is based on the usage of the insight parameter. More details are available on the Number Insight pricing page. Please contact your sales or account manager for exact pricing in your local region.
