Telephone numbers in India

Fixed (landline) numbers

Subscriber Trunk Dialling (STD) codes are assigned to each city/town/village, with the larger cities having shorter area codes (STD codes), the smallest being 2 digits. For example,

11 - New Delhi, Delhi
22 - Mumbai, Maharastra
33 - Kolkata, West Bengal
44 - Chennai, Tamil Nadu
20 - Pune, Maharashtra
40 - Hyderabad, Andhra Pradesh
80 - Bangalore, Karnataka
1572 - Sikar, Rajasthan

A full list of area codes in India is [http://www.bsnl.co.in/stdsearch.php available with BSNL]

Landline numbers are at most 8 digits long (usually in major metros). The total length of all phone numbers (STD code and the phone number in India is constant at 10 digits, for example 5623200000 signifies a STD code i.e. 562 Agra & the phone number 3200000. Due to the availability of multiple operators offering fixed line services (either over wire or wireless), there is an operator-code for each telephone number, which is the first digit in the phone number. These are:

2 - BSNL and MTNL
3 - Reliance Communications
4 - Bharti Airtel
6 - Tata Indicom

Thus, a number formatted as 020-30303030 means a fixed-line Reliance number in Pune, while 011-20000198 is an MTNL fixed line in Delhi and 033-45229320 is an Airtel number in Kolkata, and 01572-212334 is an BSNL number from Sikar.

No prefix is required to call from one landline to another in the same STD area. A prefix of "0+STD code" is required to dial from a landline phone in one STD code area to another. A prefix of "0+STD code" is required to dial from a mobile phone in India to any landline number, irrespective of STD area.

For example, to call a landline number in Delhi, one would have to dial
* from a land line in Delhi : only the required phone number
* from a land line in Mumbai : 011 and then the required phone number
* from a mobile phone anywhere in India : 011 and then the required phone number

There are some exceptions to this general rule for STD areas falling close to each other, where "0" is sometimes replaced with "95" e.g. to dial Delhi from Gurgaon, one dials 9511+landline number.
