SMS Verify API
An API that enables SMS messaging for account security and business critical communications.
Secure and Engage Your User Base
Ensuring the validity of your users is extremely important in preventing fraud. A great way to do that is to attach a verified phone number to end-user accounts, ideally when they first register. From there, communicate more effectively and provide timely, personalized information in the form of text-based alerts, reminders, notifications, invites and other automated messages.
HIGH QUALITY, DIRECT-TO-CARRIER ROUTES
Connects directly to hundreds of carriers around the world and employs a waterfall approach across multiple routes to help ensure the highest delivery and conversion rates.
SECURE, TIME-BASED, ONE-TIME PASSCODE (TOTP)
Verifies users in real time by sending a one-time code via SMS that can be used to authenticate a known user, verify a transaction or block fraudsters from opening illegitimate accounts.
TeleSign sends an SMS with an OTP along with transaction details, and the user then replies with the code and approves or denies the request.

We were looking at several vendors, but TeleSign won out because of their demonstrated security expertise, the quality of their global SMS authentication offering, and because they understood the importance of the overall experience. TeleSign worked closely with us to ensure our UI/UX provided the best experience possible and would be easily adopted.
