Understanding bulk SMS and its regulatory guidelines using AM, VM, AD and other codes for promotional marketing purposes

SMS (Short messaging service) is part of telecom, which is regulated by Government of India. Few years ago, SMS prices were very low, as low as a paisa per SMS or free in some cases leading to SMS flood in the country. Every small, medium or large business uses this tool to communicate their business proposal with their potential customers using a new generation broadcasting tool called Bulk SMS.

This resulted in unwanted messages to mobile users and hence to regulate such unwanted messages or calls TRAI (Telecom Regulatory Authority of India) has given guidelines to regulate SMS for commercial purpose. With several amendments and guidelines around promotional SMS marketing there have been several changes and rules to govern.
MS is classified as Promotional SMS and Transactional SMS

Promotional SMS:

Mobile subscribers can register with NDNC with in following categories:
