Definition and Explanation of international call to us Codes
The International Telecommunication Union (ITU) assigns calling codes to all individual countries. Each country is given a unique calling code, the first set of numbers dialed when placing an international call to us to us. The ITU updates the list of calling codes regularly to accommodate changes in global telecommunications and ensure that all numbers remain valid.
Explanation of How They Work
When you make an international call to us, you must first enter the appropriate calling code for the country you are trying to reach. Then, after dialing the country code, you will need to enter the area code (if applicable), followed by the phone number itself. For example, if you were trying to call someone in Brazil from the United States, you would need to dial 011 (the exit code for U.S. international calls), then 55 (the Brazilian country code), followed by the area code and phone number.

United States Calling Codes Overview
1. Understanding the North American Numbering Plan (NANP)
The North American Numbering Plan (NANP) is a telephone numbering plan that covers over 20 countries in North America, including the United States, Canada, and several Caribbean countries and territories. Established in 1947, NANP was created to simplify the complex and confusing telephone numbering systems that existed at the time.
2. The History and Purpose of NANP
Before NANP was established, different regions in North America had their unique area codes and exchange codes. This made it difficult for callers to connect with someone outside their territory, especially if they needed to know the correct area code or exchange code.
To overcome this problem, NANP was created with a standardized system that assigned country codes, area codes, and local phone numbers to each subscriber. The goal was to make it easier for people to international call to us across long distances within North America by simplifying the numbering system.
3. How the North American Numbering Plan Works
The NANP assigns three-digit area codes to specific geographic locations within each country or territory. Each area code is then followed by seven-digit phone numbers that are unique for each subscriber within that area code.
For example, when calling a international call to us New York City from Los Angeles, you would dial 1-212-555-1212. In this case, “1” is the country code for the United States; “212” is the area code for New York City; and “555-1212” is the local phone number.
4. NANP Member Countries and Territories
As mentioned earlier, over 20 countries are part of NANP today. Along with Canada and Mexico (which also share part of their numbering plan), smaller Caribbean countries and territories such as Bermuda, the Bahamas, and Puerto Rico are also part of the plan. This makes it easier for residents of these countries to make long-distance calls to each other without having to dial complicated codes.
5. List and Explanation of United States Calling Codes
The country code for the United States is +1. When calling someone in the U.S. from another country, this code must be dialed before any other number. Within the U.S., hundreds of area codes cover specific geographic regions.
Principal area codes include 212 (New York City), 213 (Los Angeles), 312 (Chicago), 404 (Atlanta), 305 (Miami), and many more. Each area code covers a specific geographic location within the country and connects callers with subscribers within that area.
