You're standing there with your thumb hovering over the call button, staring at a string of digits that looks more like a math equation than a phone number. It happens. Honestly, figuring out how to make international calls from USA used to be a nightmare of expensive calling cards and confusing prefix codes that changed depending on whether you were calling a landline in London or a cell phone in Tokyo.
Things are different now.
But even with WhatsApp and FaceTime dominating the scene, sometimes you just have to pick up the actual phone. Maybe it’s a government office, a bank that won't accept "app calls," or a relative who still thinks a smartphone is a fancy paperweight. You need to know the sequence. It’s basically a digital handshake. If you miss one finger, the whole thing falls apart and you get that annoying "your call cannot be completed as dialed" recording.
The Secret Code: 011 and Why It Matters
Before you do anything else, you have to tell the American phone system to let you out. That’s what 011 does. It’s the US exit code. Without it, your phone thinks you’re just trying to call someone in another state.
Wait.
There is one big exception. If you are calling Canada, Puerto Rico, or most Caribbean nations, you don't use 011. These places are part of the North American Numbering Plan (NANP). For them, you just dial 1 followed by the area code, exactly like you’re calling from New York to Los Angeles. It’s a weird quirk of geography and telecom history that trips people up constantly.
For everywhere else—France, India, Brazil, Australia—the sequence is non-negotiable:
- Dial 011 (the exit code).
- Punch in the Country Code (e.g., 44 for the UK, 91 for India).
- Add the Area Code or City Code.
- Finish with the Local Subscriber Number.
If you're using a mobile phone, you've got a shortcut. You can hold down the "0" key until a + symbol appears. That "+" basically tells the network, "Hey, I’m making an international call," and it automatically replaces the 011. It’s way easier. You should probably just use the plus sign.
Stop Giving Your Mobile Carrier Free Money
Let’s be real for a second. If you just dial an international number directly from your Verizon or AT&T plan without a specific international add-on, you are going to get slaughtered on the bill. We’re talking $2.00 or $3.00 a minute. It’s highway robbery.

If you do this often, you need to look at VoIP (Voice over Internet Protocol).
Google Voice is a classic for a reason. It’s free to set up, and the rates for calling abroad are usually just a few cents per minute. You load $10 onto the account, and it lasts for months. Rebtel is another one that people swear by because it uses local phone lines to bridge the gap, meaning the call quality doesn't drop just because your Wi-Fi is acting sketchy.
Then there are the "Big Three" apps: WhatsApp, Signal, and Telegram.
They’re great. They’re encrypted. They’re free. But they only work if the person on the other end has the app too. If you're calling a hotel in Italy to confirm a reservation, WhatsApp isn't going to help you if they only have a desk phone. In those cases, Skype is still a surprisingly solid backup. You can buy "Skype Credit" and call any landline in the world for basically nothing.
The "Zero" Trap and Mobile Formatting
This is where most people mess up.
A lot of international numbers are written with a (0) in the middle. For example, a UK number might look like +44 (0) 20 7946 0000. When you are learning how to make international calls from USA, you must remember to drop that zero. That leading zero is only for people calling within that country. If you include it while calling from the States, the call won't go through.
- Wrong: 011 + 44 + 020...
- Right: 011 + 44 + 20...
It seems like a small detail, but it’s the number one reason international calls fail.
Time Zones Are Your Worst Enemy
It’s 2:00 PM in New York. You’re feeling productive. You decide to call your business partner in Berlin.
Stop.

It’s 8:00 PM there. They’re having dinner. Or maybe you're calling Sydney? It's 6:00 AM the next day. You’re literally calling from the past. Always check the UTC (Coordinated Universal Time) offset. The US has multiple time zones, and Europe is generally 6 to 9 hours ahead of the East Coast.
The easiest way to check? Type "time in [City Name]" into Google. Don't guess. Being the person who wakes up a client at 3:00 AM is a bad look.
Landlines vs. Mobile Costs
Did you know it actually costs more to call a mobile phone in many countries than it does to call a landline?
In the US, we’re used to the person receiving the call paying (or using their minutes). In most of Europe and Asia, the "Calling Party Pays" system exists. This means if you call someone's cell phone in Spain from the USA, you might be charged a higher rate by your provider to cover the "termination fee" that the Spanish mobile network charges.
Digital Nomad Hacks and Virtual Numbers
If you’re running a business and need to receive calls from abroad while you're in the USA, look into getting a virtual local number.
Services like Zadarma or OpenPhone allow you to buy a "local" number in London or Tokyo that rings right on your smartphone in Chicago. This way, your international contacts don't have to worry about how to call the USA—they just dial a local number, and you pick up. It makes you look way more established than just being "that guy in America."

Common Country Codes You’ll Actually Use
It helps to have a few of these memorized so you aren't constantly googling.
- Mexico: 52
- United Kingdom: 44
- India: 91
- China: 86
- France: 33
- Germany: 49
- Japan: 81
- Brazil: 55
- Australia: 61
Checking Your Equipment
Sometimes the tech just fails.
If you are using a workplace PBX (those big office phone systems), you might need to dial "9" first just to get an outside line before you even start with the 011. And if you are on a "Wi-Fi Calling" setting on your iPhone or Android, ensure your internet connection is stable. A jittery connection will make you sound like a robot underwater, which is frustrating for everyone involved.
Actionable Next Steps to Save Money Right Now
Don't just start dialing. You'll regret the bill.
First, check if your current mobile provider has a "World Saver" or "International Preferred" add-on. Often, for $5 or $10 a month, they’ll drop the per-minute rate from $2.50 down to $0.05. If you're going to talk for more than four minutes, the plan pays for itself instantly.
Second, download a secondary app like Google Voice or Skype for those moments when you need to call a non-app number. Keep $5 of credit on there just in case of emergencies.
Third, double-check the destination's current time. Use a site like TimeAndDate.com to be 100% sure you aren't calling in the middle of the night.
Finally, remember the "+" trick. Save your international contacts in your phone with the + [Country Code] [Number] format. This way, whether you are in the US or traveling abroad, the phone will always figure out the right exit code for you automatically. It’s the single best way to future-proof your address book.
The days of $500 phone bills are over, provided you’re smart about the sequence. Dial 011 (or +), skip the trunk zero, and use data-based apps whenever you can.
