How to Dial India from the USA: Step-by-Step

Before comparing prices, let's cover the basics of dialing India from any US phone.

Dialing Format

To call India from the United States, use this format:

011 + 91 + Area Code (if landline) + Phone Number

Or on mobile phones:

+91 + Area Code (if landline) + Phone Number

Breaking it down:

• 011 — US international exit code (use + on smartphones). This is the ITU-T E.164 standard exit code for North America.
• 91 — India's country code (ISO 3166-1 alpha-2). This is assigned by the International Telecommunication Union.
• Area code — Required for landlines (2-4 digits depending on city). India uses a hierarchical numbering plan managed by the Telecom Regulatory Authority of India (TRAI).
• Phone number — The local number (remaining digits)

Important: Always remove the leading "0" from Indian mobile numbers when dialing internationally. For example, if the local number is 09876543210, dial +91 9876543210 (without the leading 0).

Example: Calling a Mobile Phone in India

Indian mobile numbers are 10 digits and don't require an area code. The first digit indicates the mobile operator (6, 7, 8, or 9).

Example 1: Calling a mobile number starting with 9

From US landline: 011-91-98765-43210
From US mobile: +91 98765 43210

Example 2: Calling a mobile number starting with 8

From US landline: 011-91-81234-56789
From US mobile: +91 81234 56789

Important: Never include the leading "0" when dialing from outside India. The "0" is only used for domestic calls within India.

Example: Calling a Landline in Mumbai

Mumbai's area code is 22, and landlines have 8 digits. Mumbai is in the Maharashtra state and uses the STD code 022 for domestic calls, but you only need "22" when calling internationally.

Example: Calling a Mumbai landline

From US landline: 011-91-22-2345-6789
From US mobile: +91 22 2345 6789

Format breakdown:

• 011 or + = US exit code
• 91 = India country code
• 22 = Mumbai area code (remove leading 0)
• 23456789 = 8-digit landline number

Example: Calling a Landline in Delhi

Delhi's area code is 11, and landlines also have 8 digits:

From US landline: 011-91-11-2345-6789
From US mobile: +91 11 2345 6789

India Area Codes: Complete Reference

When calling landlines in India, you'll need the city's area code. Here are the codes for major Indian cities:

Note: Mobile numbers in India always start with 6, 7, 8, or 9 and are 10 digits long. They don't require area codes. This numbering system was standardized by the Department of Telecommunications, Government of India.

Additional Major Cities

For a complete list of all Indian area codes, refer to the TRAI numbering plan. Here are more cities you might need:

Best Time to Call India from the USA

India Standard Time (IST) is UTC+5:30, which creates a significant time difference with US time zones. India does not observe daylight saving time, so the time difference remains constant throughout the year. Here's when to call for a reasonable hour on both ends:

Pro tip: If you're on the West Coast, evening calls work well—when it's 9 PM in Los Angeles, it's 10:30 AM in India (next day), perfect for a morning conversation.

Comparing All Methods to Call India from USA

Here's a comprehensive comparison of every method available, with current pricing as of December 2025:

Method 1: Traditional Phone Carriers

Major US carriers charge premium rates for international calls without a plan:

Rates as of December 2025. Source: AT&T International Rates, Verizon International Calling, T-Mobile International Rates. Always verify current rates with your carrier.

Total cost for a 30-minute call: $75 - $120

These rates make occasional international calls extremely expensive. A weekly 30-minute call to family would cost $300-$480/month.

Method 2: Carrier International Plans

Some carriers offer international calling add-ons:

Limitation: These plans require a monthly commitment whether you use the minutes or not.

Method 3: Prepaid Calling Cards

Traditional calling cards advertise low rates but come with significant drawbacks:

Advertised rates: $0.02 - $0.05/minute

Hidden fees to watch for:

• Connection fees: $0.50 - $1.00 per call
• Weekly maintenance fees: $0.50 - $2.00/week
• Rounding: Calls rounded up to nearest 3-5 minutes
• Expiration: Balance expires after 30-90 days of inactivity

Real cost example: A card advertising $0.03/min might actually cost $0.15-$0.25/min after fees.

Method 4: VoIP Services (Best Value)

Voice over Internet Protocol (VoIP) services route calls through the internet, dramatically reducing costs:

Rates as of December 2025. Source: HelloAirDial Rates, Google Voice International Rates, Skype Rates.

Total cost for a 30-minute call: $0.30 - $2.70

VoIP services offer 95% savings compared to traditional carriers.

Method 5: Free App-to-App Calls

If both parties have internet access and the same app, calls are completely free:

• WhatsApp — Free voice and video calls
• Google Duo/Meet — Free video calls
• FaceTime — Free (Apple devices only)
• Facebook Messenger — Free voice and video

Limitation: Requires both parties to have the app installed and a stable internet connection. Not suitable for calling landlines or when the recipient doesn't have data access.

Cost Comparison: 30-Minute Weekly Call to India

Let's calculate annual costs for someone calling India for 30 minutes every week:

*Free apps require recipient to also have app and internet access.

VoIP saves you $6,200+/year compared to pay-per-minute carrier rates.
