How SMS verification can boost your business
Build trust and fight fraud
SMS verification helps your business to limit spam accounts, fight fraud, build a better customer experience, and reduce churn. Defend login and sign up from unwanted visitors by verifying user possession of number - and make the process even more secure by adding second-factor authentication.
Optimize conversion rates
One of our clients boosted conversions by 11% using our SMS verification solution for single-factor authentication (SFA). In addition, Sinch helps you stay on top of your conversion rate with our reporting API and real-time statistics on user interactions - helping you achieve an optimal conversion rate.
Totally verified votes
Netherlands based Oceanwide Expeditions specialize in expedition-style journeys to Antarctica and the Arctic via their own fleet of ice-strengthened vessels. When the company needed a secure way to run a global competition based on votes, it was essential that all customer logins and votes were verified. Vote buying or fraudulent vote gathering was strictly off limits. That's where Sinch came in.
The SMS verification solution provided by Sinch was the answer to our problem. The implementation was straightforward; follow-up was quick and accurate - all we needed for a successful partnership.
