Why my sender ID isn't honored in some countries?

A sender ID is a customizable, short alphanumerical name (up to 11 characters) that appears as the sender name of your messages. It is useful to make your messages more easily identifiable by your customers.

Unfortunately, some countries (United States, Canada, India...) do not accept custom sender ID. In United States and Canada, sender ID is automatically replaced by a local phone number. For other countries that do not support it, it is overwritten by a short, generic name to help improve deliverability (like "NOTICE").

Sender ID is supported in most European countries.
