Easily verify users at signup by confirming phone number ownership, reducing fraudulent accounts and speeding up account onboarding.
Collect just a phone number and quickly verify account ownership, leading to quicker and easier signups.
Prevent fraud and spam
Verify a real person is registering by leveraging the phone in their hand. Not verifying users at sign up can lead to bad actors in your system. Twilio Verify stops accounts from being created by bots, and can reduce fraud and associated costs by blocking premium and toll-free numbers.
Verify translates both SMS and voice verifications into 29 languages, allowing for increased global usability. The service automatically selects the right translation based on the phone number country code, or you can override and choose the language.
Delivered as a modern REST API, you can implement the Verify solution in a single sprint without worrying about availability, reliability or service security. We handle that for you. Just sign up and get started within minutes. Everything can be accessed immediately; we don’t hide our API behind a sales person.
The less complexity we have to manage, the faster we can move. Twilio enables us to move quicker and focus on building the best experience for our users.
Verifying a number doesn’t require us to persistently store information about your customers, therefore we ensure our platform doesn’t maintain personally identifiable information.
Customizable code length
Choose the right level of security for your application and increase usability by specifying between 4 - 10 digits for the verification code.
We ensure that the SMS only goes to a real handset and not to web portals, reducing the risk of compromised desktops in the authentication chain.
Delivery to 205 countries. The Verify service is built on a world class communications platform, allowing for high rates of SMS and voice delivery around the world. Works with both landlines and mobile devices.
Pay only for verifications
With Verify you only pay for verified requests. We use a high quality SMS platform and automatically select the right route across our network of aggregators and carriers, giving us confidence to only charge you when the verification is complete.
We comply with changing carrier and country regulations and use multiple short and long codes and registered sender IDs to ensure your verification messages are not filtered out.
Twilio performance dynamically scales up and down as volume requires. We typically handle hundreds of verification requests per second. We also use positive feedback to replace failing routes on the fly.
