Phone Numbers in India
Indian mobile numbers have ten digits and start with 6, 7, 8 or 9, so a mobile number called from abroad looks like +91 98xxx xxxxx. Since mobile number portability, the first digits no longer tell you which operator a number is on.
Landlines start with an STD code of two to four digits, for example 11 for Delhi, 22 for Mumbai, 33 for Kolkata, 44 for Chennai and 80 for Bengaluru. Inside India the STD code is dialed with a leading 0 (011 for Delhi); from abroad that 0 is dropped, so a Delhi number becomes +91 11 xxxx xxxx.
India has one time zone, India Standard Time, at UTC+5:30. Toll-free numbers starting 1800 usually cannot be reached from outside India. Suspected fraud calls and messages can be reported through Chakshu on the government's Sanchar Saathi portal.
How to Dial a +91 Number
- Start with your country's international prefix: 011 from the US and Canada, 00 from most of Europe, or simply + from any mobile phone.
- Dial 91.
- Dial the national number. If it starts with a 0, drop that leading zero.
Missed Call From +91?
Unrecognized international numbers are a common pattern in Wangiri ("one ring") scams: the caller hangs up after one ring hoping you call back a premium-rate number. If you don't know anyone in India, don't call back. If the call matters, the caller will try again or leave a message.
