Full Form of DND
What is DND?
Do Not Disturb (DND) is a telecom service in India, regulated by the Telecom Regulatory Authority of India (TRAI), that allows mobile users to block unsolicited commercial communications (UCC), commonly known as spam calls and messages. Users can register their mobile numbers on the National Do Not Disturb Registry by dialing 1909 or through their service provider’s app. Once registered, telemarketers are prohibited from contacting the registered number for promotional purposes unless the user has given explicit consent. DND is widely used by Indian consumers to reduce nuisance from telemarketing, and it is enforced through strict penalties on violators. The service categorizes messages into transactional and promotional, with promotional ones blocked by default. For government exams like IBPS, SSC, and UPSC, knowledge of DND and TRAI’s role is relevant under the consumer protection and telecom regulatory framework. DND is also a common phone setting for silencing notifications during meetings or sleep, but in Indian regulatory parlance, it specifically refers to the anti-spam registry.
