1. What Is The International Telephone Code For The United States and How Do I Use It?

The international telephone code for the United States is +1. To call a US phone number from another country, dial your country’s exit code, followed by +1, and then the 10-digit US phone number (area code + local number). This ensures your call is correctly routed to the United States.

Calling the US involves a few key steps to ensure your call connects properly. Understanding these steps and the correct codes can save you time and frustration. Here’s a detailed breakdown:

  • Dial Your Country’s Exit Code: This code tells your local phone network that you are making an international call. It varies from country to country. For example:

    • In most European countries, the exit code is 00.
    • In the United Kingdom, it is also 00.
    • In Australia, it is 0011.
    • In Japan, it is 010.

    You can easily find your country’s exit code with a quick online search if you’re unsure.

  • Enter the United States Country Code (+1): After the exit code, dial the US country code, which is +1. This code directs your call to the United States’ telephone network.

  • Include the 3-Digit Area Code: The area code is a three-digit number that specifies a particular region or city within the US. It’s a crucial part of the phone number. For example:

    • 212 is a common area code for New York City.
    • 310 is used in Los Angeles, California.
    • 415 serves San Francisco, California.

    Always ensure you have the correct area code for the location you are trying to reach.

  • Dial the 7-Digit Local Number: This is the unique seven-digit number assigned to the specific phone line you are calling. Combine it with the area code to form the complete 10-digit US phone number.

Example:

Let’s say you are calling a number in New York City (area code 212) with the local number 555-1234 from the UK (exit code 00). You would dial:

00 (exit code for UK) + 1 (US country code) + 212 (area code) + 555-1234 (local number)

So, the complete number you dial is 0012125551234.

Tips for Successful International Dialing:

  • Double-Check the Codes: Always verify the exit code for your country and the area code for the US location you are calling. Incorrect codes can lead to failed calls or being connected to the wrong number.
  • Use the “+” Symbol on Mobile Devices: On most mobile phones, you can use the “+” symbol as a universal replacement for the exit code. Simply enter +1 followed by the area code and local number. The phone will automatically use the correct exit code based on your current location.
  • Consider Time Zones: Be mindful of the time difference between your location and the US to avoid calling at inconvenient hours.
  • Save Contacts with Full International Numbers: When saving US contacts in your phone, include the +1 country code. This makes it easier to call them from anywhere in the world without having to remember the codes.

By following these steps and keeping these tips in mind, you can confidently and successfully make international calls to the United States. Always ensure you have the correct codes and consider the time zone differences for a smooth and successful call.

2. Why Is the United States Country Code ‘+1’?

The country code +1 was assigned to the United States, along with Canada and some Caribbean nations, because of the early development of the North American Numbering Plan (NANP). This system grouped these countries into a single numbering area for telecommunications efficiency.

The allocation of country codes is managed by the International Telecommunication Union (ITU), a specialized agency of the United Nations responsible for global telecommunications. The ITU assigns country codes to ensure that each country has a unique prefix for international dialing, preventing conflicts and ensuring calls are routed correctly.

The decision to assign +1 to the United States and its territories was made in the early days of telephony. At that time, the American Telephone and Telegraph Company (AT&T) played a significant role in establishing the North American Numbering Plan (NANP). The NANP was designed to create a unified numbering system across North America, making it easier to manage and route telephone calls efficiently.

Here are the key reasons why the +1 code was chosen:

  • Early Standardization: The US, being one of the first countries to develop a comprehensive telephone system, took the lead in creating a standardized numbering plan. This plan included Canada and several Caribbean countries to facilitate seamless communication across the region.
  • Efficiency: Assigning a single country code to multiple countries that were closely linked geographically and economically simplified the routing of calls. It reduced the complexity of international dialing and made it more user-friendly.
  • Historical Context: The decision was made during a time when the infrastructure and regulatory landscape for telecommunications were very different. AT&T, as a dominant player, influenced the standardization process in North America.
  • Geographic Proximity: The close geographic proximity and economic ties between the US, Canada, and the Caribbean made a unified numbering plan a logical choice. It fostered better communication and trade relations.

Over time, the NANP has been adapted and updated to accommodate the growing demand for telephone numbers and the introduction of new technologies like mobile phones and the internet. However, the basic structure and the +1 country code have remained consistent.

Today, the NANP is administered by the North American Numbering Plan Administration (NANPA), which is responsible for allocating telephone numbering resources within the +1 area. This includes assigning area codes and ensuring that telephone numbers are used efficiently.

The +1 country code is a historical artifact that reflects the early days of telephony and the unique relationship between the United States, Canada, and the Caribbean. While the telecommunications landscape has changed dramatically since then, the +1 code remains a fundamental part of the international dialing system.

3. What Are the Steps for Calling the United States from Another Country?

Calling the United States from another country involves dialing a series of codes in the correct order. Here’s a step-by-step guide:

  • Step 1: Dial the Exit Code: This code allows you to dial out of your country. It varies depending on where you are calling from (e.g., 00 in many European countries, 011 from North America).
  • Step 2: Enter the US Country Code: The country code for the United States is +1.
  • Step 3: Dial the Area Code: This is a three-digit code that identifies a specific region within the US.
  • Step 4: Enter the Local Number: This is the seven-digit phone number of the person or business you are trying to reach.

Example:

To call a New York City number (area code 212) with the local number 555-1234 from the UK (exit code 00), you would dial:

00 + 1 + 212 + 555-1234

Understanding the difference between a country code and an area code is crucial for making successful phone calls, especially when dialing internationally. These codes serve different purposes and are essential for routing calls to the correct location. Here’s a detailed explanation of each:

  • Country Code:
    • Definition: A country code is a numerical prefix used when dialing internationally to identify a specific country. It is necessary for directing a call from one country to another.
    • Purpose: The primary purpose of a country code is to ensure that international calls are correctly routed to the destination country. Without the correct country code, the call cannot be completed.
    • Examples:
      • +1 is the country code for the United States and Canada.
      • +44 is the country code for the United Kingdom.
      • +49 is the country code for Germany.
      • +86 is the country code for China.
    • Usage: When making an international call, you must first dial the exit code of the country you are calling from, followed by the country code of the destination. For example, if you are calling the United States from the United Kingdom, you would dial 00 (the UK’s exit code) followed by 1 (the US country code).
  • Area Code:
    • Definition: An area code is a three-digit number used to identify a specific geographic region within a country. It is necessary for directing a call to the correct local network.
    • Purpose: The primary purpose of an area code is to divide a country into smaller regions for telephone routing. This allows telephone companies to efficiently route calls to the correct local exchange.
    • Examples (in the United States):
      • 212 is an area code for Manhattan, New York City.
      • 310 is an area code for parts of Los Angeles, California.
      • 415 is an area code for San Francisco, California.
    • Usage: After dialing the country code (if making an international call), you dial the area code followed by the local phone number. For example, to call a number in Manhattan with the area code 212 and the local number 555-1234 from outside the United States, you would dial [Exit Code] + 1 (US Country Code) + 212 (Area Code) + 555-1234 (Local Number).
  • Key Differences Summarized:
Feature Country Code Area Code
Definition Identifies a specific country Identifies a specific region within a country
Purpose Routes calls to the correct country Routes calls to the correct local network
Digits Varies (usually 1-3 digits) Typically 3 digits
Usage Used for international dialing Used for national and international dialing
Examples +1 (USA), +44 (UK), +49 (Germany) 212 (NYC), 310 (LA), 415 (San Francisco)
  • Importance of Using Both Codes Correctly:
    • International Calls: When making an international call, you must use both the country code and the area code (if applicable) to ensure that the call is routed correctly. Omitting either code will result in a failed call.
    • National Calls: Within a country, you may only need to use the area code and local number. However, in some countries, you may need to dial a national prefix before the area code.
  • Additional Tips:
    • Exit Codes: Remember to use the correct exit code for the country you are calling from. The exit code allows you to dial out of your country and initiate an international call.
    • “+” Symbol: On mobile phones, you can use the “+” symbol as a universal replacement for the exit code. Simply enter + followed by the country code, area code, and local number.
    • Check Codes: Always double-check the country code and area code before making a call to ensure that you have the correct information.

By understanding the difference between country codes and area codes and using them correctly, you can ensure that your calls are routed successfully, whether you are dialing locally or internationally.
