Step 1: Understand Basic International Dialing from USA
From the US, all international calls start with the exit code 011, followed by India's country code 91.
General format: 011 + 91 + [India number without leading 0]
Alternative: Use + on smartphones (hold 0) → +91 + [number]
Example for a Delhi mobile:
Domestic in India: 09876543210
From USA: 011 91 98765 43210 or +91 98765 43210
Step 2: Dialing India Mobile Numbers from USA
Mobile numbers are 10 digits, starting with 6–9.
Format: 011 91 [10-digit mobile number]
Examples:
- Mumbai mobile 98765 43210 → 011 91 98765 43210
- Bangalore Jio 70012 34567 → 011 91 70012 34567
Never add a leading 0 — it's only for domestic dialing in India.
Step 3: Dialing India Landline Numbers from USA
Landlines have area codes (2–4 digits) + subscriber number (total 10 digits).
Format: 011 91 [area code without 0] + [subscriber number]
Common area codes:
- Delhi: 11
- Mumbai: 22
- Bangalore: 80
- Chennai: 44
- Hyderabad: 40
Example: Delhi landline (011) 2345 6789 → 011 91 11 2345 6789
Step 4: Dialing India Toll-Free Numbers from USA
Toll-free: 1800-XXX-XXXX
Format: 011 91 1800 XXX XXXX
Note: Not free from USA — you'll pay international rates.
Step 5: Cheaper Alternatives – Use VoIP Apps
Carrier rates are $0.15–$0.30/min. Switch to VoIP for 1–2¢/min or unlimited.
