Sender ID

A Sender ID is what appears on people’s phones to show who the SMS is from. When a person sends an SMS, the Sender ID is set to that person’s phone number. But if sent using an API, this alpha-numeric variable can be set to any 15 digits or 11 characters in the range a-z, A-Z plus 0-9. Brands love this because it enables them to set their brand name as the SenderID. There are local restrictions and in some markets, such as North America or Brazil, the Sender ID cannot be changed. In some other destinations only certain senders are allowed (i.e. only alpha senders, or international numerics) so senders not complying with local regulations may be overwritten, either by the operator or by Mitto, to ensure the message is delivered.
