Do you know what P, S, T, and G next to your SMS really mean?

The classification system for SMS messages by TRAI—Promotional, Service, Transactional, and Government—to help users identify message types and stay protected from spam.

The Telecom Regulatory Authority of India (TRAI) has classified SMS messages into four categories—P for Promotional, S for Service, T for Transactional, and G for Government—to help users better understand the nature of the messages they receive on their phones.

This classification aims to provide transparency in SMS communications and protect users from spam and scams.

•    P - Promotional: Messages from brands or businesses, including offers, advertisements, and marketing content.
•    S - Service: Informational updates, reminders, or general notifications related to services used by the recipient.
•    T - Transactional: Critical messages such as OTPs, bank transaction alerts, purchase confirmations, or other essential transaction-related communications.
•    G - Government: Official messages from government departments or bodies providing authorized information to citizens.

This classification system has been implemented to bring more clarity and transparency to SMS communication, enabling users to safely manage their mobile communications in an increasingly digital world.
