The Correct Format for Calling the US

Making a call to the USA from another country is a straightforward, four-step process. You will combine your country’s exit code, the US country code, a regional area code, and a local phone number. Following this sequence ensures your call connects successfully every time. This format works whether you want to know how to call the USA from a landline or how to call the USA from a cell phone.

Step 1: Find Your International Exit Code

Before you can dial any international number, you must first enter your country’s exit code. This code signals to your phone provider that you are making a call outside your country’s network. The exit code varies depending on your location.

Many countries, particularly in Europe, use 00 as their exit code. However, this is not universal. You can find your specific code with a quick online search or by checking with your phone service provider.

Tip: A simple way to handle the exit code is to use the plus sign (+) on your mobile phone. The + symbol is the universal substitute for any country’s exit code and is part of the international dialing standard established by the International Telecommunication Union (ITU).

Here are a few examples of exit codes:

Step 2: Add the US Country Code (+1)

Immediately after the exit code, you will dial the country code for the USA, which is 1. This digit directs your call to the North American Numbering Plan (NANP), a unified phone network that includes the USA, Canada, and several Caribbean nations. The assignment of +1 as the calling code for the United States dates back to a 1964 global plan that designated “1” for the North American region.

The full US country code is +1. When you dial, the complete sequence will look like [Your Exit Code] + 1.

Who else uses the +1 country code? The +1 country code is not exclusive to the USA. It is shared by all members of the NANP. This group includes:

• Canada
• Bermuda
• Guam
• Puerto Rico
• Many Caribbean islands, such as the Bahamas, Barbados, and Jamaica.

Even though these calls use the same country code, they are still considered international calls and will be billed accordingly.

Step 3: Dial the 3-Digit Area Code

Next, you need to dial the three-digit area code for the specific city or region you are trying to reach within the USA. The area code, known as a Numbering Plan Area (NPA), narrows down the call’s destination from the entire country to a smaller geographic zone. The concept of area codes was developed by AT&T in the 1940s to automate long-distance dialing across the US.

Every US phone number is assigned to one of these area codes. For example, to call someone in Los Angeles, you would likely use the area code 213. Without the correct area code, your call will not connect.

Step 4: Enter the 7-Digit Local Number

The final step is to dial the seven-digit local phone number. This number is unique to the individual phone line within its area code. The seven-digit standard was created to unify various local numbering systems as direct long-distance dialing became common.

This local number is composed of two parts:

• A three-digit exchange code (NXX)
• A four-digit station number (xxxx)

Putting it all together, the complete international dialing format for a US phone number is +1-NPA-NXX-XXXX.

Let’s look at a complete example of how to call the USA. If you are calling from the United Kingdom (exit code 00) to a number in New York City (area code 212) with the local number 555-0123, you would dial:

00 - 1 - 212 - 5550123

If you use a mobile phone, you can simplify this dialing sequence to:

+1 - 212 - 5550123

By following these four steps, you can confidently dial the US and connect your call without any issues.

Breaking Down a US Phone Number

Understanding the components of a US phone number makes the dialing process much clearer. Every number in the USA follows a consistent 10-digit format, which includes a geographic area code and a local number. This structure is essential for routing your call correctly across the vast US phone network.

What is an Area Code?

An area code is the three-digit number at the start of any 10-digit USA phone number. The North American Numbering Plan Administration (NANPA) assigns these codes to specific geographic regions. The USA currently has 359 active area codes. While large states like California and Texas have dozens of codes, some states like Alaska (907) and Wyoming (307) use a single area code for the entire state.

The area code serves several key functions:

• It routes your call to the correct geographic part of the USA.
• It helps the phone network manage a massive number of unique numbers.
• It allows you to identify the general location a call is coming from.

Without the correct area code, your call to the USA will not connect. It is just as important as the +1 country code.

Key US Area Codes by City

When you call a major city, you will use one of its primary area codes. Population growth often requires new codes to be added to a region, but the original ones remain famous. Here are some of the most well-known USA area codes for major cities.

Note: Always confirm the specific area code for the person or business you are calling. A city can have multiple USA area codes.

Landline vs. Mobile Numbers

You cannot tell if a US phone number belongs to a landline or a mobile phone just by looking at it. Both number types use the exact same 10-digit format: a 3-digit area code followed by a 7-digit local number.

This is because the US has a system called “number portability.” This system allows people to keep their existing phone number when they switch from a landline to a mobile service (or vice versa). A number that was once for a home phone could now be for a smartphone. Because of this, the country code and number format remain the same regardless of the device. This makes every US phone number look identical in structure.

Troubleshooting Common Calling Issues

Sometimes, an international call to the USA doesn’t connect on the first try. You might encounter a confusing error message or just silence. These issues are usually easy to fix once you identify the cause. The problem could be with your dialing sequence, your phone plan, or even the recipient’s device.

Why Your Call Isn’t Connecting

If your call fails, you might hear a message like, “The number you have dialed has calling restrictions.” This can happen for several reasons. Understanding these potential roadblocks helps you solve the problem quickly.

Your call might not connect because:

• Your Number is Blocked: The person you are calling may have blocked your number.
• Recipient’s Device Settings: The recipient might have “Do Not Disturb” mode or a call-filtering app active on their phone.
• Carrier Restrictions: Your cellular plan may not include international calling, or the recipient’s provider could be blocking the call. Your number might even be flagged as spam by their carrier.
• The Line is Unavailable: The person’s phone could be turned off, out of service, or already on another call.

Double-Checking the Dialing Sequence

The most common reason for a failed call is a simple mistake in the dialing sequence. Before you try again, quickly verify that you have entered the number correctly. A small error, like using the wrong exit code or forgetting the area code, will prevent your call from connecting to the US.

Follow this checklist for your next dialing attempt: 1. Start with the Exit Code: Begin with your country’s international exit code. You can use the + symbol on a mobile phone as a universal substitute. 2. Add the US Country Code: Immediately follow the exit code with 1, the country code for the USA. 3. Enter the Area Code: Dial the correct 3-digit area code for the city or region in the US you are trying to reach. 4. Finish with the Local Number: Type the final 7-digit local phone number.

Managing International Calling Costs

Making an international call can be expensive, and you want to avoid surprise charges on your phone bill. The cost of calling the USA can vary significantly depending on your provider and plan. Fortunately, you can manage these costs effectively.

Always check your phone plan’s rates for international calling to understand the per-minute cost in USD. Many modern solutions can help you save money.

Pro Tip: Use the Internet to Your Advantage You can significantly reduce or even eliminate international calling costs. Connect to a secure Wi-Fi network at a hotel or café. This allows you to use messaging apps for free calls. You should also consider disabling data roaming on your phone to prevent your device from using expensive foreign networks for data.
