1. What Is The Country Code for the USA?
The country code for the United States of America is +1. This code is essential when dialing a U.S. phone number from another country. Including +1 at the beginning of the number ensures your call is correctly routed to the United States.
The North American Numbering Plan (NANP) governs telephone numbering in the United States, Canada, and several Caribbean nations. According to the NANP Administration, the +1 country code was established to streamline international call routing to these regions. Without this standardized code, international calls would be far more complicated, requiring manual routing by operators.
2. How Do I Dial a US Number from Abroad?
To call the United States from another country, follow these steps:
- Dial the international exit code This code allows you to dial out of your current country. It’s often “00,” but it varies by country. You can also use “+” on a mobile device, which automatically inserts the correct exit code.
- Enter the U.S. country code: Which is 1.
- Add the U.S. area code: A three-digit number that specifies the region within the U.S. you’re calling.
- Complete with the local phone number: This is the seven-digit number of the person you are calling.
For example, if you are calling a number in the 212 area code (New York City) from the UK, you would dial 00-1-212-XXX-XXXX.
3. Why Does the United States Have a Country Code of +1?
The United States has a country code of +1 because it is part of the North American Numbering Plan (NANP). The NANP includes the U.S., Canada, and several Caribbean countries.

The +1 code was assigned to the NANP region due to its large population and advanced telecommunications infrastructure.
3.2 Benefits of the NANP
The NANP offers several advantages, including:
- Simplified Dialing: Standardized codes make it easier for people to call between countries within the NANP region.
