What to know when calling India

  • DND (Do Not Disturb) registration with TRAI is mandatory to scrub; commercial calls to DND-registered numbers attract fines up to ₹10,000.
  • Hindi/English bilingual greetings are universal for business; regional language opening matters in Tamil Nadu, West Bengal, and Kerala.
  • Indian mobile numbers are 10 digits starting with 6, 7, 8, or 9. Operators have been free to port across these prefix ranges since MNP, so prefix no longer reliably identifies the carrier.

Regulation & compliance (India)

  • TRAI's TCCCPR 2018 mandates principal-entity registration for any commercial calling/SMS; un-registered traffic gets blocked.
