SMS Regulations for India

Businesses must adhere to strict regulations when conducting SMS marketing in India, including the National Do Not Call (NDNC) Policy and various rules that limit message volume and timing.

Prerequisites

Before sending SMS messages via the Marketing Engine, you must configure your SMS settings and set up your sender destination.

Key Regulations:

Sender ID

• The "From" address displayed on the recipient’s mobile device must be registered before sending SMS in India.

• Unregistered sender IDs may result in message delivery failure, but charges will still apply.

Message Volume

• A sender number can send a maximum of 6 identical messages per hour to a single recipient.

Timing Restrictions

• SMS marketing messages must be sent between 9 AM and 9 PM IST, as per TRAI regulations.

• Messages sent outside this window may be blocked.

NDNC (National Do Not Call List)

• Marketing Engine strongly recommends checking the NDNC list before sending promotional messages to prevent them from being blocked.

Opt-in Messages

• Opt-in messages can only be sent to users who have submitted an official approval document.

• Web-based opt-ins are not accepted for SMS approval.

• Transactional routes must not be used for opt-in messages.

Stock-Related Messages

• Messages related to shares and stocks require prior approval from SEBI-registered entities and stockbrokers.

• These messages cannot be sent via transactional routes.

Following these guidelines ensures compliance and prevents disruptions in your SMS marketing efforts in India.
