India Phone Number Format: Mobile, Landline and +91 Examples

Perkenalan

The India phone number format is simpler than it first looks: a regular Indian number, mobile or landline, has 10 digits.

What changes is how those digits are grouped, whether a 0 goes in front, and whether the number is written for someone in India or for a reader abroad with +91.

This guide follows the Department of Telecommunications (DoT) numbering plan and papers from the Telecom Regulatory Authority of India (TRAI), covering mobiles, landlines, the +91 form, special series and clean storage. Every example uses X in place of real digits.

India Phone Number Format: How Numbers Are Structured

India's rules come from the National Numbering Plan 2003. It set a 10-digit national number for both fixed-line and mobile services. That core stays the same wherever the call comes from; only the prefix in front of it changes.

The first digit has a job. 0 is the trunk prefix and 1 is kept for special services such as 1800 toll-free numbers.

The 2003 plan reserved level 9 for mobiles; TRAI papers from 2019 and 2024 show mobile numbers in levels 8, 7 and 6 as well.

Indian Mobile Number Format (10 Digits)

An Indian mobile number always has 10 digits. TRAI describes mobile service as a closed numbering system, meaning all 10 digits are dialed for calls within India, whether the other phone is next door or in another state.

There is no area code to add or remove.

The first five digits are what TRAI calls the MSC code, allocated to operators in blocks, and the last five identify the subscriber, hence the written form 98XXX XXXXX.

Nationwide mobile number portability means the prefix doesn't reliably reveal the network. Calling a mobile from a landline needs a 0 in front: the DoT accepted TRAI's May 2020 recommendation, and the 0 has been mandatory for fixed-to-mobile calls since 15 January 2021.

Indian Landline Number Format and STD Codes

A landline number in India has two parts: an STD code for the local charging area (the numbering plan calls it an SDCA or trunk code) and a subscriber number.

STD codes are 2, 3 or 4 digits and subscriber numbers are 8, 7 or 6 digits, so the pair always totals 10. The largest cities have the shortest codes.

Within the same area, a landline caller dials only the 6 to 8 digit subscriber number. From a landline in another area, or from any mobile, you dial 0, the STD code and the subscriber number.

That is why landlines are written with the 0 in front, as in 011-XXXX XXXX for New Delhi.

Writing an Indian Number With +91 (International Format)

The international version is +91 followed by the 10-digit number, with any domestic 0 removed. The ITU assigns country code 91 to India, and India's numbering plan follows the ITU's E.164 layout of country code plus national number.

1. 1Start with the complete number. For a landline, include the STD code: 011-XXXX XXXX.
2. 2Delete the leading 0. The landline becomes 11 XXXX XXXX. A mobile such as 98XXX XXXXX has no 0 to delete unless it was saved as 098XXX XXXXX.
3. 3Put +91 in front: +91 11 XXXX XXXX or +91 98XXX XXXXX.
4. 4Remove spaces and dashes for software: +9111XXXXXXXX or +9198XXXXXXXX, 13 characters including the plus sign.

To dial the number from another country, replace the plus sign with that country's exit code.

Indian Mobile and Landline Number Examples

Each sample shows one number in three contexts. X stands in for real digits, so none of these is a working line; keep the grouping and put in the digits you actually have.

For readers in India, 98XXX XXXXX is enough. Anywhere seen abroad, such as a website or email signature, use +91 98XXX XXXXX, and always keep a landline's STD code.

Toll-Free and Special Numbers in India

Special numbers sit in level 1 and don't follow the 10-digit subscriber pattern. The best known is 1800. TRAI describes it as a free phone service: the caller pays nothing and the called party bears all charges.

These numbers run from 8 to 13 digits, written as 1800, a service code and the number, for example 1800 XXX XXXX.

• 1800: toll-free. The organization receiving the call pays.
• 1860: Universal Access Service. Calls are charged to the caller or split between caller and receiver.
• 140: 10-digit numbers (140XXXXXXX) allocated to telemarketers.
• 160: a series the DoT created in May 2024 only for service and transactional calls. Calls from financial entities such as those under the RBI, SEBI, PFRDA and IRDA start with 1601.

The DoT says operators must verify each entity before assigning a 160 number, and it asks people to report suspected fraud through the Chakshu facility on the Sanchar Saathi portal.

Formatting Indian Numbers in Forms, CRMs and Spreadsheets

One badly stored number can break a dialer import or a text campaign. Keep a single format for storage and add spacing only for display.

• Store +91 and 10 digits: no spaces, dashes or brackets, giving +9198XXXXXXXX for a mobile.
• Validate by length: require exactly 10 digits after +91. A rule that insists on 6 to 9 as the first digit rejects every landline.
• Strip the trunk 0 on import: an 11-digit entry that begins with 0 loses the 0 before +91 is added.
• Give toll-free numbers their own type: 1800 and 1860 numbers vary in length, so a mobile rule will misread them.
• Format spreadsheet columns as text: otherwise the software may drop a plus sign or leading 0, or turn a long number into scientific notation.

The same habits carry over to other countries. The US phone number format guide covers +1 numbers, the Canada phone number format guide explains the shared +1 layout, and the UK phone number format guide shows +44 replacing the 0.

Common Formatting Mistakes

1. 1Keeping the 0 after +91. +91 011-XXXX XXXX has one digit too many. The trunk prefix belongs only to dialing inside India.
2. 2Dropping the STD code. A landline saved as XXXX XXXX works only for a landline call within the same area.
3. 3Saving mobiles with a 0. The 0 is dialed from a landline, but it isn't part of the number. Store the 10 digits or +91 and the 10 digits.
4. 4Saving 0091 instead of +91. 00 adalah awalan internasional yang digunakan di India, dan negara lain menggunakan kode keluar yang berbeda. Tanda plus memungkinkan setiap telepon menyediakan pasokannya sendiri.
5. 5Membaca awalan sebagai operator. Dengan portabilitas, digit pertama menunjukkan operator mana yang menerima blok tersebut, bukan siapa yang melayani pelanggan sekarang.

Kesimpulan

Format nomor telepon India memiliki panjang tetap dan dua awalan. Nomor ponsel dan telepon rumah memiliki 10 digit, angka 0 berada di depan jika aturan panggilan domestik mengharuskannya, dan +91 menggantikan angka 0 untuk siapa pun yang berada di luar negeri.

Telepon rumah membawa kode STD 2 hingga 4 digit, ponsel ditulis sebagai dua kelompok yang terdiri dari lima orang, dan 1.800 nomor tidak membebankan biaya apa pun kepada penelepon.

Penomoran di India terus berkembang, dan TRAI membuat rekomendasi telepon rumah lebih lanjut pada tahun 2025, jadi periksalah pemberitahuan terkini dari Departemen Pertahanan sebelum mengubah aturan validasi.
