India was assigned +91 in 1949, putting it in ITU zone 9 with the rest of South + West Asia. Here is what every Indian number looks like and the quirks that catch most foreign callers.
India has used the +91 country code since 1949, when the ITU placed it in zone 9 alongside Iran +98, Pakistan +92, Afghanistan +93, Sri Lanka +94, Myanmar +95 and the Maldives +960. India was assigned the "1" suffix as one of the first members of the zone.
Indian landline area codes are called STD codes (Subscriber Trunk Dialing) — 011 Delhi, 022 Mumbai, 080 Bangalore, 033 Kolkata, 044 Chennai, 040 Hyderabad. Each city has 2-5 digits including the leading 0. The international call prefix from India to abroad is 00 (called the ISD code — International Subscriber Dialing).
Indian mobile numbers always start with 6, 7, 8 or 9 (the "+91 6/7/8/9 XXXXXXXXX" format). All Indian mobiles are 10 digits — same length whether you are dialing Reliance Jio, Bharti Airtel, Vi (Vodafone Idea), BSNL or MTNL. The first 4 digits are the operator prefix, the last 6 are the subscriber number.
India is the world's largest mobile market. As of 2024, India has 1.16 billion mobile subscriptions across Reliance Jio (~470M), Bharti Airtel (~390M), Vi/Vodafone Idea (~220M) and BSNL/MTNL (~80M) — more than China's mobile subscriber base. Jio launched in 2016 and became the largest single mobile operator in the world by 2020.
An Indian phone number in international format is written as +91 [STD code without 0] [local number] for landlines, or simply +91 [10-digit mobile]. For example, +91 22 1234 5678 for a Mumbai landline, or +91 98 1234 5678 for a mobile starting with 9.
The "0" that Indian landlines start with (011 Delhi, 022 Mumbai) is the national trunk prefix — dropped when dialing internationally. Indian mobiles do not use a leading 0; the 10-digit number 9812345678 is dialed identically domestically and internationally (just prefix with +91 from abroad).
From the financial corridors of Bandra Kurla Complex in Mumbai to the tea estates of Darjeeling, every Indian number lives behind a +91. Pick the STD code that matches your customer city.
Every country uses a different international exit code before the +91 India country code. From any mobile, the + symbol replaces the exit code automatically — so +91 98 1234 5678 works worldwide. Always drop the leading 0 from Indian landlines (011 Delhi → 11) when dialing from abroad.
