1. Understanding The United States Phone Code
The United States phone code, or country code, is a numerical prefix used when dialing a phone number in the United States from another country; it’s the first step in connecting with someone in the USA. You need to know the United States phone code to reach family, friends, or business associates across international borders. We will explain the structure of US phone numbers and how the country code fits into the overall dialing sequence.
1.1 What Is The Country Code For The United States?
The country code for the United States is +1. When dialing a US number from abroad, you must dial +1 before the area code and the local number. This ensures that the international telecom network correctly routes your call to the United States.
1.2 How Does The U.S. Phone Number System Work?
The U.S. phone number system follows the North American Numbering Plan (NANP), which includes the United States, Canada, and some Caribbean countries. A complete phone number consists of the country code (+1), a three-digit area code, and a seven-digit local number. The area code designates a specific geographic region within the country.
1.3 Why Is Knowing The U.S. Country Code Important?
Knowing the U.S. country code is essential for anyone who needs to make international calls to the United States. Without it, your call won’t be connected, and you won’t be able to reach your intended recipient. It ensures that your call is routed correctly through the international telephone network.
2. Step-By-Step Guide To Dialing The United States From Abroad
Dialing the United States from another country requires a specific sequence of numbers to ensure the call is routed correctly. We’ll break down the dialing process into simple, easy-to-follow steps, including using the exit code, the U.S. country code, and the area code. This section will cover everything from the international exit code to the local U.S. number.
2.1 Step 1: Dial The International Exit Code
The first step in making an international call is to dial the international exit code for the country you are calling from. This code tells the phone system that you are about to dial an international number. The exit code varies from country to country. For example, in many European countries, the exit code is 00. In North America, it’s 011. You can also use the “+” symbol on many mobile phones, which automatically substitutes the correct exit code for your current location.
2.2 Step 2: Enter The United States Phone Code (+1)
After dialing the exit code, the next step is to enter the U.S. country code, which is +1. This code tells the phone system that you are calling the United States.
2.3 Step 3: Dial The Area Code
The area code is a three-digit number that identifies a specific geographic region within the United States. You must dial the correct area code to reach the specific location you are trying to call. A list of area codes can be found online or through a directory service.
2.4 Step 4: Enter The Local Phone Number
The final step is to enter the seven-digit local phone number. This is the unique number assigned to the individual or business you are trying to reach.
2.5 Example Of Dialing A U.S. Number From Abroad
Let’s say you are calling a number in New York City (area code 212) from the United Kingdom (exit code 00). The number you want to call is 555-1234. Here’s how you would dial it:
- Dial the UK exit code: 00
- Enter the U.S. country code: 1
- Dial the New York City area code: 212
- Enter the local phone number: 555-1234
The complete number you would dial is: 00 1 212 555-1234

3. Common Mistakes To Avoid When Dialing The United States
When dialing the United States from abroad, several common mistakes can prevent your call from going through. We’ll highlight these errors, such as forgetting the exit code, U.S. country code, or area code, and provide tips to avoid them. Understanding these pitfalls can save time and frustration when placing international calls.
3.1 Forgetting The International Exit Code
One of the most common mistakes is forgetting to dial the international exit code for the country you are calling from. This code is necessary to tell the phone system that you are making an international call. Always check the exit code for the country you are in before dialing.
3.2 Omitting The U.S. Country Code (+1)
Another frequent error is omitting the U.S. country code (+1). Without this code, the phone system will not know that you are trying to call the United States. Make sure to always include +1 after the exit code.
3.3 Dialing The Wrong Area Code
Dialing the wrong area code can also prevent your call from reaching the intended recipient. Double-check the area code before dialing to ensure you have the correct one. You can find a list of area codes online or through a directory service.
3.4 Not Including The Area Code For Mobile Numbers
In the United States, you must also include the area code when dialing a mobile number. Even if you are calling from the same area code, you still need to dial all ten digits (area code + local number).
3.5 Using Incorrect Formatting
Using incorrect formatting, such as adding extra digits or symbols, can also cause issues. Make sure you are following the correct dialing sequence: Exit Code + 1 + Area Code + Local Number.
4. Understanding U.S. Area Codes
U.S. area codes are three-digit numbers that identify specific geographic regions within the country. We’ll explain the purpose of area codes, how they are assigned, and provide a comprehensive list of area codes by state and major city. This section will help you easily locate the correct area code for any location within the United States.
4.1 What Is A U.S. Area Code?
A U.S. area code is a three-digit number that precedes the seven-digit local phone number. It helps to route calls to the correct geographic region within the United States. The North American Numbering Plan Administrator (NANPA) assigns area codes to ensure each region has a unique identifier.
4.2 How Are Area Codes Assigned?
Area codes are assigned based on geographic boundaries and population density. Densely populated areas may have multiple area codes, while less populated regions may have only one. New area codes are introduced when existing ones are exhausted due to the increasing demand for phone numbers.
4.3 List Of Area Codes By State And Major City
Below is a list of area codes for some major cities and states in the United States:

5.3 International Calling Cards
International calling cards are prepaid cards that allow you to make international calls at a lower rate. You purchase a card with a specific amount of credit and then use it to make calls by dialing a toll-free number and entering a PIN. While calling cards can be cost-effective, be aware of hidden fees and expiration dates.
