Whether you're a traveler needing to reach a business in New York, an expat trying to connect with family in California, or someone working with American clients, knowing how to call the USA from abroad is essential. But international calling isn't always intuitive—between country codes, formats, and calling apps, it's easy to get confused.
In this guide, we'll walk you through exactly how to call the USA from another country, including:
Let's break it all down step by step.
Here's a quick checklist:
Here's the general format you'll use:
+1 (area code) (local number)
Let's break that down:
Let's say you want to call a number in Miami, Florida, with the local number 555-1234 and the area code 305.
You would dial:
+1 305 555 1234
Let's take a few popular countries and show exactly how you'd call the USA:
| From | Format | Example |
|---|---|---|
| UK | +1 (XXX) XXX XXXX | +1 212 555 7890 |
| India | 00 1 (XXX) XXX XXXX | 00 1 323 444 7890 |
| Colombia | +1 (XXX) XXX XXXX | +1 917 222 3344 |
| Australia | 0011 1 (XXX) XXX XXXX | 0011 1 415 999 4567 |
| Mexico | 00 1 (XXX) XXX XXXX | 00 1 646 777 1212 |
🔔 Note: The prefix (00, 0011, etc.) depends on your country's international dialing code. Most mobile phones automatically convert the + symbol for you.
International calls can be expensive if you're using traditional mobile carriers. Here are smarter alternatives:
Apps like:
💡 ZenCall lets you make pay-per-minute calls directly from your browser with no subscription required, making it perfect for quick calls or business communication. For detailed comparisons, see how ZenCall stacks up against other popular services when making international calls.

| Carrier | Sample Add-On |
|---|---|
| Vodafone | Unlimited USA calls for $10/month |
| Claro (Latin America) | USA calls for COP$500/min |
| T-Mobile (USA) | Free Wi-Fi calls to U.S. |
In countries like India or the Philippines, you can purchase credit from a local carrier to call the U.S. These rates vary but are usually higher than online alternatives. For those looking to avoid traditional phone cards entirely, there are modern alternatives for international calling that offer better rates and convenience.
U.S. phone numbers follow a standard format:
(Area Code) - XXX - XXXX
Example:
(312) 555-1212 → Chicago, Illinois
Always include +1 or the international dialing prefix before the area code.
U.S. numbers are 10 digits long, not including the +1. Don't add international prefixes after the country code.
Use the full international format with +1 even if the number looks local. Mobile networks abroad won't recognize 1-800 or local-only numbers.
Toll-free U.S. numbers (like 1-800, 1-888) often don't work from abroad, or they may incur charges. Workaround:
The USA spans six time zones, so be careful about when you call.

| Denver | Mountain | UTC -7 / -6 (DST) |
| Los Angeles | Pacific | UTC -8 / -7 (DST) |
| Alaska | AKST/AKDT | UTC -9 / -8 |
| Hawaii | HST | UTC -10 |
💡 Use tools like timeanddate.com to avoid waking someone at 3AM.
