India Landline vs. Mobile Phone Numbers

Complete India landline and mobile phone numbers are both always 10-digits long, but they are structured somewhat differently.

Landline numbers have an area code and a local subscriber number that may or may not both be included when written. Mobile phone numbers are self-contained and are always written with all 10-digits.

In addition, with landline numbers, the area codes and the subscriber numbers can both vary in length. This can be quite confusing if you are not familiar with Indian phone numbers - and sometimes even if you are.

India Landline Phone Number Format *

0	aaa	nnn nnnn
NLD code	area code	local subscriber number

India Mobile Phone Number Format *

0	9x	nnn nnnnn
NLD code	mobile access code	mobile subscriber number

* Phone number formatting notes:

• The landline number format shown above is somewhat notional. In practice, area codes can vary in length from 2-digits to 4-digits and subscriber numbers from 6-digits to 8-digits. A complete landline number is exactly 10-digits and with any of the following combinations: 2:8, 3:7, or 4:6 (area code:subscriber number).
• Landline numbers are written in varying ways, such as: 11-digit number complete with NLD code (e.g., 080 45481800), as a 10-digit number without NLD code (e.g., 80 45481800), or as just the local subscriber number of 6- to 8-digits (e.g., 45481800). The area code may be broken out or may not be broken out (e.g., 80 45481800 vs. 8045481800)
• Mobile numbers may be written with or without the NLD code. And they may or may not break out the leading ' 9x ' access code (e.g., 94 45481800 vs. 9445481800)

India National Long Distance Dialing

Dialing an NLD call in India is easy if you follow these simple steps.

1. If you have an 11-digit local subscriber number starting with '0', you are ready to start dialing

If your India destination phone number starts with a '0' - e.g., 080 45481800 or 094 451 23456, then start dialing.

2. Otherwise, confirm that you have a proper 10-digit local subscriber number

If you don't have a 10-digit number, then you probably have a landline number without the area code. You can find the area code here.
