Bulk SMS FAQ

Bulk SMS is a service that enables individuals or businesses to send large volumes of SMS messages to multiple recipients simultaneously. It is commonly used for marketing, notifications, alerts, and promotions.
Yes, DLT registration is mandatory for businesses sending transactional and promotional SMS in India. TRAI (Telecom Regulatory Authority of India) has mandated DLT registration to ensure compliance, reduce spam, and ensure transparency in messaging.
DLT registration helps telecom operators verify the identity of the sender and the content of the message to ensure it complies with TRAI guidelines, reducing unsolicited messages and spam.
To complete DLT registration, businesses need to register with a telecom operator or DLT platform. This involves submitting documents like PAN, business address proof, and message templates for approval.
The following documents are typically required:
  • PAN card of the business
  • Proof of business address (e.g.: GST certificate, MSME, Incorporate certificate, and Company registration certificate etc..)
  • Authorized person’s ID proof (Pan, Aadhaar, Passport, Voter ID)
  • Letter of authorization
No, DLT registration is mandatory for all businesses that wish to send SMS in India. Without registration, messages will be blocked or fail to be delivered.
After DLT registration, you can send transactional and promotional SMS, as long as they comply with TRAI’s rules. Transactional SMS includes important updates, while promotional SMS includes marketing content.
A Sender ID is the name or number displayed on the recipient’s mobile phone when they receive the SMS. It can be a brand name, company name, or an alphabetic identifier, depending on the registration process.
You can register a Sender ID through your SMS service provider's DLT platform. It requires approval by the telecom operator after submission, and only registered Sender IDs can be used for sending SMS.
