What is a country calling code?

A country calling code is the numeric prefix you dial before a national phone number to route a call to a specific country. For example, +1 reaches the United States and Canada, +44 reaches the United Kingdom, and +91 reaches India. The plus sign stands in for the international access code your network uses.

How do I dial an international number correctly?

Start with your exit or access code (or the + symbol on a mobile), add the destination country code, then the area or city code without its leading zero, and finally the local subscriber number. So a London line looks like +44 20 7946 0000.

What does the plus (+) sign mean in a phone number?

The + is a universal placeholder for the international dialing prefix. Saving numbers in +country-code format means they connect from any country without editing the access code, which is why it is the recommended way to store contacts.

Why do the United States and Canada share the country code +1?

Both countries belong to the North American Numbering Plan, a shared system that also covers several Caribbean nations. They use the same +1 country code but are separated by distinct three-digit area codes.

Do I need to remove the leading zero from a phone number when calling internationally?

Usually yes. Many countries print a trunk prefix, often a 0, for domestic calls. When dialing from abroad you drop that leading zero after the country code. For example, a UK mobile written as 07700 900000 becomes +44 7700 900000.

How do I call India from the United States?

From the US, dial 011 (the US exit code) + 91 + the 10-digit Indian number. On a mobile, simply use + instead of 011 — so +91 98765 43210 dials correctly from anywhere. letsdial makes this automatic with one-click dialing.

Why do Indian mobile numbers always start with 7, 8, or 9?

India's telecom regulator (TRAI) reserves the 7xx, 8xx, and 9xx prefixes exclusively for mobile services. Fixed landlines use regional STD codes (e.g. 011 for Delhi, 022 for Mumbai). If a number starts with 6, it is also a mobile — that block was opened more recently.

What are the best hours to reach Indian businesses from the US or Europe?

Indian Standard Time (IST) is UTC+5:30 and does not observe daylight saving. Standard Indian office hours are 10 AM–6 PM IST. From New York, that is roughly 12:30 AM–8:00 AM ET — so early morning US time aligns best. From London, aim for 4:30 AM–2:00 PM GMT.

How does a local +91 virtual number increase answer rates when calling India?

Indian contacts are far more likely to pick up a call from a familiar +91 number than from an unknown international code. letsdial assigns you a real Indian virtual number — your outbound caller ID appears local, which typically lifts answer rates by 2–3× compared to calling from a foreign number.

Can I call India from my laptop or desktop using letsdial?

Yes. letsdial runs as a web app and desktop client — no hardware required. Your +91 virtual number works on iOS, Android, browser, and IP desk phone. You can switch devices mid-call without dropping the connection or changing your caller ID.

Tips for calling India

4 things to check before you dial internationally

Know India's mobile prefix

Indian mobile numbers start with 7, 8, or 9 under +91. Landlines use 2-digit city codes (011 Delhi, 022 Mumbai, 080 Bengaluru). Confirm the type before calling — mobile rates may differ on your carrier.

WhatsApp first, call second

India has one of the world's largest WhatsApp user bases. Sending a WhatsApp message before calling signals you are a real contact, warms the conversation, and is often preferred over a cold call.

Show a local +91 caller ID

India's TRAI-mandated DND registry blocks many international numbers. A letsdial +91 virtual number appears local, avoids spam filters, and is far more likely to be answered.

IST is UTC+5:30 — no daylight saving

India Standard Time never changes. Business hours are 9 AM–6 PM IST. From London, call between 3:30 AM–12:30 PM GMT. From New York (ET), the window is 10:30 PM–7:30 AM the following morning.
