91 Country Code: India (+91)
Country code 91 (+91) belongs to India. India uses the international dialing code +91, assigned by the International Telecommunication Union (ITU) under the E.164 standard. The ISO 3166-1 alpha-2 code is IN.
You will see the same code written several ways depending on origin: +91 (universal + prefix, works from mobile), 0091 (from countries that use 00 as their international exit code — most of Europe, Asia, and Latin America), 011 91 (from the US and Canada), 0011 91 (from Australia), or the bare 91. All refer to the same India country code.
Other ways people search for the same thing: "country code for india", "india country code", "india international code", "india phone code", "india dial code", "india dialing code", "india country calling code", "india country prefix", "india isd code", "+91 country code", "91 country code", "0091 country code", "how to call india from us", "what is the country code for india", "what is the international code for india", "what country is +91", "what country code is 91", "indian country code", "india telephone code". All of these resolve to +91 for India.
Indian mobile numbers are always 10 digits and begin with 6, 7, 8, or 9 after the country code. Landline area codes are "STD codes" ranging from 2 digits (Mumbai 22, Delhi 11) to 4 digits for smaller towns. The domestic trunk prefix 0 must be dropped when calling from abroad — dial +91 followed by the 10-digit number directly.

India Telephone System Facts
Calling India Successfully: Common Mistakes & Best Practices
Most failed calls to India come from one of four mistakes, not from network problems. The most common is mishandling the leading 0: domestically, India numbers are written with 0 at the front (e.g. 09876543210), but that 0 is the domestic trunk prefix and must be removed when calling from outside India. Dial +91 followed directly by the local number without the 0.
The second is misreading the area code on landline numbers — India area codes are not uniform length (Mumbai 22, Delhi 11, Bangalore 80), so confirm the city before dialing. The third is dialing during off-hours — India uses Hindi business hours and consumer phones are usually answered between 8 AM and 9 PM local time. The fourth and most expensive mistake is assuming your US carrier's WiFi calling feature makes the call cheap. It does not — see WiFi calling vs VoIP for international calls for why.
For scam-call awareness: +91 is the legitimate India country code, and most unsolicited calls from +91 numbers are legitimate calls from India-based businesses, hospitals, family members, or call centers serving US customers. Caller-ID spoofing exists, so if a call from a +91 number claims to be from a US government agency, your bank, or the IRS, hang up and call the agency back on its published number. Real authorities never demand payment over the phone.
When you are ready to place a call, the cheapest reliable route is to dial +91 from your browser using Kinvo — no app, no carrier add-on, and the per-minute rate is shown before you connect so there are no bill surprises.
