Alphanumeric Senders
Overview
Alphanumeric originators are combinations of letters (alphabets) and numbers (digits) for sending SMS messages to mobile phones. Alphanumerics work one way and are the most common form of originator worldwide except for the USA and Canada.
Alphanumeric originators do not have a country of origin and have to be registered in destination countries individually. Some countries may require additional registration processes to ensure the alphanumeric sender ID meets local compliance requirements.
