India Business Calling Etiquette
Cultural context for calling contacts in India — know what to expect before you dial.
Network & carriers
India operates one of the world's largest mobile networks by subscriber count, with numbering managed by the Telecom Regulatory Authority of India (TRAI).
Numbering format
Indian mobile numbers are 10 digits and always start with 6, 7, 8, or 9 — landlines use a mix of STD area codes plus local numbers.
Calling culture
India spans a single time zone (IST, UTC+5:30) despite its size, which simplifies scheduling — but confirm business hours around regional holidays, which vary by state.
Good to know
India expanded mobile numbers from 9 to 10 digits in the early 2000s just to keep up with the sheer scale of new subscribers joining the network.
