Real-Time Telephone Verification
Protect your business and your users with TeleSign
TeleSign's solutions allow internet-based companies to verify and authenticate their users using one of the simplest, most widely-deployed pieces of technology available: the telephone.

When you decide to use one of TeleSign's authentication solutions, you won't need to deploy any hardware or ask your users to download special software to verify their identity. Simply add a call to TeleSign's cross-platform SOAP API to your registration or checkout page, and you can verify your users seamlessly - and in real-time - directly from your own website.
