// Calling Etiquette

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.
