Twilio is an SMS provider that handles standard one-time password (OTP) delivery to your applicants. By default, SMS verification messages are dispatched through our managed Twilio account.

Get started with Twilio

Note

Make sure that target regions are enabled in your Twilio account.

SMS messages are only delivered via a digital channel, and not directly from Sumsub. We send SMS notifications via Twilio and SMSAPI, Lanck Telecom, and Prelude.

All countries are available and dynamically distributed between these providers, so there is no separate list of preset countries for each of them.
