Sender ID / Header Registration
Lock in the letter- and number-based headers that put your brand at the top of every message you send.
The Sender ID — also called a Mask or Header — is one of the pieces that matters most when you register on any operator's DLT platform.
Transactional and Service (Implicit/Explicit) traffic runs on alphabetic headers, while Promotional Sender IDs are numeric. Whichever the type, each one has to be registered on its own with every operator's DLT platform.
You will need a completed Principal Entity registration and the Entity ID it produces before any Sender ID can be registered with the operators.
