Calling Within the US – An Overview of USA Country Codes

USA Country Code



What is the USA Country Code?

The country code for the United States of America (USA) is +1. When calling the US from another country, dial +1 followed by the area code and local phone number

Here’s why country codes are important:

  • Routing: Country codes ensure your international calls get directed to the correct country.
  • Identification: A +1 at the beginning of a number immediately shows that it’s a US-based phone number.

Example: To call a friend in Los Angeles (area code 213) from the UK, you’d dial: 00 1 213 [rest of the phone number]

Country codes were created in the 1960s. The ITU gave each nation its unique code. These codes are used worldwide for accurate routing of international calls.

The USA country code also has another purpose: it identifies phone numbers from the US. When displayed with a phone number, it shows the number is from the US.

How to Call the United States from Your Phone


Understanding the Format

  • Country Code (+1): This code tells the phone system you’re calling a number in the United States.
  • Area Code: This 3-digit code narrows down the location within the US (e.g., 212 for New York City, 310 for Los Angeles). You can find area codes online if you’re unsure.
  • Local Number: This is the 7-digit number assigned to the specific person or business you’re trying to reach.

Step-by-Step Instructions

  1. Find your phone’s dialing app: This is usually represented by a phone icon.
  2. International Dialing Prefix (if needed): Countries like India use “00” as an exit code for international calls. Check with your provider if there’s a prefix you need to dial first.
  3. Enter the US Country Code (+1): This is essential for any call to the US.
  4. Enter the Area Code: Carefully type in the correct 3-digit area code.
  5. Enter the Local Number: Type the 7-digit phone number.
  6. Press the Call Button: Your phone will start the dialing process.

Example: To call a friend in Los Angeles (area code 310) from India, you’d dial: 00 1 310 [friend’s 7-digit number]

The Importance of Country Codes

Country codes play a vital role in enabling effective communication between countries. By incorporating a country code before dialing a phone number, callers ensure seamless connectivity with their intended recipients. These codes serve as a global addressing system, facilitating efficient routing of international calls.

For example, suppose you’re in France (country code +33) and want to call a friend in the United States. By inputting the USA country code (+1) followed by their local area code and phone number, you establish a direct line of communication.

Country codes act as gateways, connecting individuals across borders and eliminating geographical barriers. With the right country code, you can connect with loved ones, colleagues, or business partners no matter where they are in the world.

Standardized Numbering Systems

Country codes are part of a standardized numbering system that enables global telephone communication. The International Telecommunication Union (ITU) assigns unique codes to each country, ensuring a standardized format for international calls.

These codes consist of one to three digits and are typically added to the beginning of a phone number. In addition to country codes, the numbering plan may include area codes or regional identifiers, further specifying the destination within a country.

Calling Beyond Borders

With the rise of globalization, understanding country codes has become increasingly important. Whether you’re traveling abroad, conducting business internationally, or maintaining long-distance relationships, knowing the correct country code is crucial for connecting across borders.

For instance, if you’re in the United Kingdom (country code +44) and need to call a business partner in the United States, familiarizing yourself with the USA country code (+1) allows for seamless communication.

Benefits of Knowing Country Codes

  • Efficiency: By including the appropriate country code, you ensure that your call is routed directly to the intended recipient without delays or misdirection.
  • Accurate Connectivity: With knowledge of country codes, you can avoid dialing errors and connect with precision, making international calls hassle-free.
  • Global Collaboration: Understanding country codes fosters opportunities for international collaboration, enabling businesses and individuals to expand their networks and reach.

By familiarizing yourself with country codes, you open up a world of communication possibilities, connecting with people across nations and making your global interactions seamless.

Understanding the North American Numbering Plan (NANP)

The NANP is the system that governs phone numbers in the US, Canada, and several other countries and territories. It’s the reason why US phone numbers have the familiar format of a 3-digit area code followed by a 7-digit local number.

The USA Country Code (+1)

  • The +1 code tells the phone system you’re trying to reach a number in the US.
  • You MUST use it when calling the US from outside the country.
  • For calls within the US, the +1 isn’t needed.

Dialing Procedures Within the USA

  1. Same Area Code:

    • Dial the 7-digit local number directly.
    • In some cases, you might need to include the area code, especially if unsure or using a landline.
  2. Different Area Code, Same State:

    • Dial the area code + the 7-digit local number.
  3. Different State:

    • Dial 1 + area code + 7-digit local number.
    • Find a list of US state area codes online or refer to the table below.

International Calls to the USA

  2. Dial +1 (US country code).
  3. Dial the area code of the region you’re calling.
  4. Dial the 7-digit local number.

Important Considerations for International Calling

  • Dialing Instructions: The order for entering country codes, area codes, and local numbers varies. Check the specific instructions for the country you’re calling.
  • Fees and Charges: International calls often incur extra costs from your phone provider. Check their rates beforehand to avoid surprise bills.
  • International Calling Services: Consider these for potentially cheaper rates and extra features (like call recording).
  • Time Zones: Be mindful of the time difference in the country you’re calling to avoid disturbing someone late at night!
  • Internet-Based Calling Apps: Apps like Skype, WhatsApp, etc., can be cheaper alternatives, especially if you have a good data connection.
