The +91 and the 0 do the same job, so a number is never written with both.
An Indian phone number checker reads a number's format first and then checks it against India's numbering plan.
This is the path one check takes. A number can be written correctly and still not be assigned to anyone, so the format check alone is not the answer.
- You enter the numberType it the way it is written at home, such as 081234 56789, or paste it with +91.
- Its format is checkedEach type of number has its own rules. A mobile needs 10 digits after +91 and starts with 06, 07, 08 or 09 at home.
- It is checked against the numbering planNumbers outside the US and Canada are checked against the numbering plan of their country, which for this page is India's.Nothing is sent to the number, so it never rings and its owner is never told.
- You see valid or invalidWith the line type and country in a few seconds, and the carrier or network where one is listed.
An Indian mobile number has 10 digits after +91 and starts with 06, 07, 08 or 09, so any other length is not a valid mobile.
These lengths come from the numbering data for India. A mobile number has 11 digits when it is written at home with its 0. Mobile and landline starts overlap, because 080 is Bangalore and 079 is Ahmedabad, so the first digit alone does not give the type.
| Number type | Starts with at home | Digits after +91 | Written at home |
|---|---|---|---|
| Mobile | 06, 07, 08 or 09 | 10 | 081234 56789 |
| Landline | 01, 02, 03, 04, 05, 06, 07 or 08 | 10 | 011 XXXX XXXX |
Eight big Indian cities have a two-digit area code, and each one leaves 8 digits for the subscriber's number.
A landline in India has 10 digits after +91, and the area code is part of them. These are the two-digit codes in the numbering data, and an X stands for any digit. The codes of other towns are longer, so they leave fewer digits for the subscriber.
| Area code | City | Written at home | Written from abroad |
|---|---|---|---|
| 11 | New Delhi | 011 XXXX XXXX | +91 11 XXXX XXXX |
| 22 | Mumbai | 022 XXXX XXXX | +91 22 XXXX XXXX |

About 15.83 million Indian subscribers asked to port their mobile number in August 2026, and seven service areas sent more than a million requests each.
Porting lets a subscriber keep a number and change network, so the digits at the start of a mobile number do not show which network it is on today. These are the seven service areas with more than a million porting requests in August 2026, and the total across all service areas was 15,829,976.

|---|---|---|---|
| UP (East) | Zone-I | 2,294,656 | 2,227,586 |

TRAI's February 2025 recommendations keep mobile numbers as they are and change how landlines dial each other.
TRAI issued its recommendations on a revised national numbering plan on 6 February 2025, in answer to a reference from the Department of Telecommunications. This table lists the points that touch how a number is written or dialed, and they are recommendations until the Department adopts them.
| Subject | What TRAI recommended |
|---|---|
| Fixed-line numbering | Move from numbering by short distance charging area to a 10-digit closed numbering scheme by licence service area. |
| Landline to landline calls | Dial a 0, then the STD code, then the subscriber number. |
| Calls to and from mobiles | Fixed to mobile, mobile to fixed and mobile to mobile dialing stays unchanged. |
| Existing subscriber numbers | They stay unchanged. |
| Time to put the scheme in place | Six months. |
| Caller ID spoofing | Put a calling line authentication framework in place, following ITU recommendation Q.3057, with a certification authority following Q.3062. |

Three common mistakes make an Indian number fail the check, and each one is quick to fix.
Keeping the 0 after +91 adds a digit.
The 0 is only for dialing inside India, so +91 081234 56789 is wrong. Drop the 0 and write +91 81234 56789.
Typing too few or too many digits makes a number invalid.
A mobile number has 10 digits after +91. With 9 or 11 it cannot be a valid mobile, so look for a missing or doubled digit.
Leaving the wrong country selected changes how the number is read.
The checker reads a number by the rules of the country selected above, so keep India selected for a +91 number. Paste a number with its + and country code and the country is read from the number itself.
These are the questions people ask most about checking Indian phone numbers.
How do I check if an Indian phone number is valid?
Enter the number in the box above with India selected. The free checker returns valid or invalid in seconds, with the line type and country. Type it the way it is written at home, such as 081234 56789, or in full as +91 81234 56789.
How many digits is an Indian phone number?
A mobile number has 10 digits after +91, or 11 written at home. A landline has 10 digits after +91, such as +91 11 XXXX XXXX.
What does an Indian mobile number start with?
Mobile numbers start with 06, 07, 08 or 09 at home, which is 6, 7, 8 or 9 after +91.
How do I write an Indian number for an app or an SMS tool?
Use the E.164 form: a plus sign, 91, then the number without its leading 0 and no spaces, such as +918123456789.
Does the Indian phone number checker show the carrier?
It shows the carrier or network where one is listed. Numbers outside the US and Canada are checked against the numbering plan of their country rather than live carrier data, so some come back with no carrier name.
Does valid mean the Indian number is active?
No. Valid means the number is real, correctly written for India and assigned. Whether a line is switched on and reachable right now is a different question, and the free HLR lookup answers it.
Can I check a whole list of Indian phone numbers?
Yes. This free tool checks one number at a time. A 7-day free trial opens CSV upload and the API, at 1 credit a number.
Does the person know I checked their number?
No. The check reads records only. No call or text goes to the number, so its owner is never told.
Why do some Indian landline numbers start with 6, 7 or 8 like mobile numbers?
Mobile numbers start with 6, 7, 8 or 9, and some landline area codes start with the same digits. Bangalore is 80 and Ahmedabad is 79, so a landline there is written 080 or 079 at home. The first digit alone does not give the type, and the line type in the result does.
What are the area codes of Delhi, Mumbai and Bangalore?
Delhi is 11, Mumbai is 22 and Bangalore is 80. Each is written with a 0 at home, such as 011, and with the +91 and no 0 from abroad, such as +91 11. The table above lists the eight cities with a two-digit area code.
Can I tell which network an Indian mobile number is on from its digits?
No. Mobile number portability lets a subscriber keep a number and change network, and about 15.83 million subscribers asked to port in August 2026 according to TRAI. The free HLR lookup shows the network a mobile number is on now.
How many phone subscribers does India have?
TRAI counted 1,360.70 million telephone subscribers at the end of August 2026, of which 1,312.25 million were wireless and 48.45 million were wireline. That is a tele-density of 95.07% when M2M cellular connections are included.
What does a number starting 1800 mean in India?
A number that starts 1800 at home is toll-free, which means the caller pays nothing and the business that holds the number pays for the call. It is a third kind of number, apart from mobiles and landlines.
You can check numbers from other countries on their own pages.
