The following table reflects our current coverage for Alphanumeric Sender ID worldwide. For countries where the “Alpha Support” column says “Yes”, you can use an alpha sender ID when sending messages to these destinations. For more info, see Getting Started with Alphanumeric Sender ID.
Pre-Registration Requirements
Some countries require a pre-registration process in order to use alpha sender ID. These are marked below with the note "Pre-Registration Required."
To qualify for pre-registration, all SMS sent to that country from your account must be "transactional" (such as as auth codes, one-time passwords / OTP, or account alerts). The only exception is Saudi Arabia, which also provides an option to register for sending promotional/marketing SMS.
To start the pre-registration process, contact Twilio Support and let us know the country where you wish to set up pre-registration.
