The National Customer Preference Register (NCPR), formerly the National Do Not Call Registry (NDNC), is intended to give Indian consumers an opportunity to limit the telemarketing calls they receive. The Telecom Regulatory Authority of India (TRAI) is the Indian governmental agency tasked with defining various policies and regulations for wireless communication service providers in India. As per TRAI regulation, every mobile service provider in India is required to set up a National Customer Preference Register (NCPR). In practice, various service providers refer to it as the Do Not Disturb (DND) registry. Telemarketers, after registration from TRAI, receive permission to access the NCPR.
