Telephone Verification

About

TeleSign’s Telephone Verification is the easiest and most powerful way to stop online fraud. Telephone Verification verifies users in real-time using their phone—the simplest and most widely deployed technology available.

Verifying a user's telephone number takes only a few seconds:

• User enters their telephone number on a website
• TeleSign immediately sends an automated voice call or SMS to the user with a one-time PIN code
• User enters this one-time PIN code onto the website
• User is verified

Traditional methods of verifying online users, such as CAPTCHA and email verification, are no longer effective at stopping spammers and fraudsters. The challenge for today’s global websites is to successfully block fraud while minimizing friction for legitimate users.

Many of the world’s leading web companies rely on TeleSign’s platform to achieve this balance.
