TRAI guideline for sender identification

TRAI directive regarding SMS sender ID

The directive no. 104-17/2008-MN dated 10th December 2008 issued by TRAI (Telecom Regulatory Authority of India) is to discourage un-solicited marketing communication being sent as SMS to mobile users. The directive mandates the prefixing of an Identification Code of three characters, consisting of Service Provider Code, Service Area Code and followed by a Hyphen. This immediately identifies the origin of the SMS, eliminates spamming and enhances the authenticity of your transactional alerts.
The regulations also required that we have unique sender id's based on criteria specified by TRAI:

  • Our SMS sender id for Transaction alerts is XY-dbAlrt
  • Our SMS sender id for Offer alerts is XY-160015
  • XY-code for access provider & service area. For e.g. AM is Airtel, Mumbai, TD is Tata Indicom, Delhi.
