+91 Country Code: India Dialing Guide
+91 is the country code for India. To call an Indian phone number from abroad, dial +91 followed by the 10-digit number. Mobile numbers start with 6, 7, 8, or 9. Landlines use area codes like 11 for Delhi and 22 for Mumbai. Here's everything you need to dial India correctly.
What Country Uses the +91 Code?
+91 is India's country code. Every phone number in India—mobile or landline—uses this code for international calls. When you see +91 at the start of a number, you're calling India.
All Indian phone numbers total 10 digits after the country code. That's it. No exceptions.
How to Dial India from the US
To call India from the US, dial +91 plus the 10-digit phone number. Skip any leading zeros you might see in locally-formatted numbers.
From a mobile phone: 1. Dial + (hold 0 on most phones) 2. Dial 91 (India's country code) 3. Dial the 10-digit number
From a landline: 1. Dial 011 (US exit code) 2. Dial 91 (India's country code) 3. Dial the 10-digit number
Example: Calling a Delhi landline
- Local format: 011-2345-6789
- International format: +91 11 2345 6789
Example: Calling an Indian mobile
- Local format: 098765 43210
- International format: +91 98765 43210
The most common mistake? Mixing +91 with the leading 0. If a number looks like 011-2345-6789 in India, drop the first 0 and dial +91 11 2345 6789.
India Area Codes by City
India's major cities use 2-digit area codes: Delhi is 11, Mumbai is 22, Bangalore is 80, and Chennai is 44. When dialing internationally, always drop the leading 0.
| City | Area Code | International Format |
|---|---|---|
| Delhi | 11 | +91 11 XXXX XXXX |
| Mumbai | 22 | +91 22 XXXX XXXX |
| Bangalore | 80 | +91 80 XXXX XXXX |
| Chennai | 44 | +91 44 XXXX XXXX |
| Hyderabad | 40 | +91 40 XXXX XXXX |
| Kolkata | 33 | +91 33 XXXX XXXX |
The area code plus local number always equals 10 digits total. Delhi uses 11 + 8 digits. Mumbai uses 22 + 8 digits. The math works the same for every city.
Calling India Mobile Numbers
Indian mobile numbers are 10 digits starting with 6, 7, 8, or 9. No area code needed—just the country code and the number.
Format: +91 [10-digit mobile number]
Example:
- Mobile: 98765 43210
- Dial: +91 98765 43210
If someone gives you an Indian mobile number starting with 6, 7, 8, or 9, it's a mobile. Dial +91 plus all 10 digits. Done.
