Sender ID Registration Requirements Per Country
International support for Alphanumeric Sender ID
The following table captures our up-to-date coverage for Alphanumeric sender support.
For countries where the “Alpha Support” column says “Yes”, you can use an alpha sender when attempting to send messages to these destinations.
Among these supported countries, some only support sending transactional messages and require sender ID pre-registration, meaning that you can only use the alpha sender you pre-register with us.
You can start the pre-registration process by contacting our support team. It's important that you test out the Alphanumeric support first before sending large batches.
