Number Verification API

Number verification API uses a direct carrier connection to check that the phone number a user enters in a digital app is linked to their mobile data network device and paired with a valid SIM card. It efficiently confirms user possession without breaking their flow or requiring them to interact with any element of the platform, enabling a seamless and trusted authentication process that helps maintain the integrity of online platforms and fosters a safer user experience.

This API is ideal for a wide range of use cases that require secure and reliable authentication without relying on SMS OTPs, including social networks, second-hand fashion e-commerce (like Vinted) and password recovery services. The verification process is transparent and enables a seamless login for users, resulting in higher conversion rates and better customer experiences.

Number Verification API: Ensuring User Authenticity in Real-Time

Additionally, this service can be incorporated into 2FA and MFA protocols to create a more robust and secure user experience by helping prevent fraud and identity theft through confirming the user’s true phone number. Having a valid and connected mobile data network device is an essential signal of a genuine user and can help reduce false positives caused by OTP delivery failures.

The numverify API returns more than 20 valuable data points including the line type of a number, such as landline, cell phone, or VoIP, so that your application knows which kind of communications to send, ensuring full compliance with the Telephone Consumer Protection Act. It can also identify risky user signals, such as a high Fraud Score or recent abusive behavior, to help you take immediate action and protect your business.
