Phone number risk detection API fraud and spam calls have become more common in recent years, and pose a threat to personal data and business security. In response, businesses that rely on phone communication have increasingly sought out ways to verify and validate user information such as phone numbers.

One solution is to use a phone validation API, which provides an automated way to check whether phone numbers are properly formatted and active, enabling businesses to keep their contact databases clean, reduce data entry errors, improve efficiency, and enhance security. A phone validation API can also confirm a number is compatible with two-factor authentication (2FA) by sending verification codes via SMS or call, making it easier to implement secure systems and processes.
