Calling India: your guide to India's country code (+91)
Product · 25 September 2025Clément Bolmont
Whether you're connecting with friends and family or reaching out to a business, calling India can be more straightforward than you might think. The first step is to master the India country code, +91, which is the key to connecting your call. For anyone outside India, understanding the correct dialling format, area codes, and common mistakes is essential for a successful connection.
This guide walks you through everything you need to know about dialling an Indian phone number from anywhere in the world.
What's the country calling code for India?
The country calling code for India is +91. This code is a universal identifier that tells a phone network your call is destined for India. It must be dialled at the beginning of every Indian phone number when you're calling from outside the country.
If you're calling from abroad on a mobile phone, the plus symbol (+) is a universal stand-in for your own country's international exit code, which means the +91 format will work automatically from anywhere. If you're using a traditional landline phone, however, you'll need to replace the + with the specific exit code of the country you're calling from. For example, if you're calling from Australia, you'd use the exit code 0011.
Your step-by-step guide to India's dialling code
Making a successful call to India involves combining a few key components in the correct order. By following this simple guide, you can ensure your call connects on the first try.
- For landline phones: to call an Indian landline from a landline phone in your country, you must first dial your country's international exit code, followed by India's country code (91), then the area code (without the leading 0), and finally the local number
The format: your country's exit code + 91 + area code + local number.
So, if you wanted to call a Delhi landline number, 011-5555-1234, from Australia (where the exit code is 0011), you'd dial: 0011 91 11 5555-1234.
- For mobile phones: calling from a mobile phone is often simpler. Instead of dialling a specific exit code, you can use the + symbol, which is a universal substitute. After the + symbol, you dial the India country code (91) and then the full 10-digit mobile number.
The format: +91 + 10-digit mobile number.
For example, to call an Indian mobile number like 9812-345-678, you'd dial: +91 9812-345-678.
What are Indian area codes?
An area code is a numerical prefix that routes phone calls to a specific geographical region within India. It's a crucial part of a landline number because it ensures your call reaches the right city or state. When calling an Indian landline from another country, you must include the correct area code to connect to the intended location.
Here's a breakdown of the area codes for some of India's major cities and regions:
City/region | Area code | How to dial |
Delhi | 011 | +91 11 |
Mumbai | 022 | +91 22 |
Bangalore | 080 | +91 80 |
Chennai | 044 | +91 44 |
Kolkata | 033 | +91 33 |
Hyderabad | 040 | +91 40 |
Mobile phone numbers are different. Indian mobile numbers all start with a specific network code and are 10 digits long, no matter where the person is in India.

What to do if your call won’t connect
If you've tried to make a call to India and it's not working, it's usually due to a small dialling error. Here are a few common issues to troubleshoot:
- Forgetting the country code: it's easy to accidentally skip the +91. Always double-check that it's there.
- Using the wrong exit code: when calling from a landline, ensure you're using the correct exit code for the country you're in. Using the + symbol on a mobile phone eliminates this error.
- Time zone differences: India Standard Time (IST) is UTC+5:30. This means it's ahead of many countries, so be sure to check the local time before you call to avoid waking someone up in the middle of the night.
Staying safe: Indian emergency numbers
While you'll hopefully never need them, it's a good idea to know the emergency numbers for India in case you or someone you know needs urgent assistance while there. The main emergency number for all services (police, fire, or ambulance) is 112. This is the national emergency number and costs nothing to call from any phone in India.

Beyond traditional calls: staying connected with apps
With the rise of smartphones and the internet, many people now use data-based apps to make calls and send messages. Services like WhatsApp, FaceTime, and Facebook Messenger allow you to make voice and video calls over an internet connection, normally at no extra cost beyond your data plan.

Rather than facing expensive roaming charges from your usual phone provider, an international eSIM gives you an affordable and reliable data plan without needing a physical SIM card. You simply buy the plan you need and get access to the internet on your phone.
