The most common Sender ID for one-way or outbound SMS applications is an 11-character Sender ID. It is an alphanumeric string that can be applied as the “from” address in the forwarded SMS text messages, MTs. It is similar to ‘Originator’ In Text-to-Join programs.
Sender ID ability is based on country and carrier requirements and is not supported or adaptable for use in the USA or Canada.
Sender IDs are not suitable for incoming SMS messages ー a short or long code is required for inbound messages instead.
