A Sender ID (technically called a Header in DLT) is the 6-character sender name that recipients see on their mobile phones when they receive an SMS from your business (for example: SAMTEC or HDFCBK).
Types of Sender IDs (Headers)
- Promotional Headers: 6-digit numeric headers (e.g.,
654321) used exclusively for marketing offers and discounts. - Transactional / Service Headers: 6-character alpha headers (e.g.,
SAMTEC) used for OTPs, order updates, invoices, and service notifications.
Rules to Ensure Fast Approval
- Brand Relevance: The header characters must directly relate to your registered company name, trade name, or brand trademark.
- No Generic Names: Generic words like
OFFERS,DISCNT, orALERTwill be rejected immediately. - Exact 6 Characters: Transactional and service headers must be exactly 6 alphabetic letters (case-insensitive).
- Provide Justification: When submitting on the portal, provide a brief note explaining how the header represents your brand.
