United States Country Code

The United States phone code is the telephone country code that is used for phone communications when a call is placed from outside of the country.

United States Country Code is +1

The United States country code is +1. The country code is necessary only when dialing a phone number to make a telephone call from another country. International callers who wish to dial a telephone number in the United States should dial first the United States’s telephone country code (+1), before the three digit area code followed by the seven digit phone number.

All phone numbers in the United States are ten digits long – (aaa)-bbb-bbbb, with aaa being the area code. Follow these easy steps to dial a phone number in the United States using the country code:

Step 1. Enter your country’s exit code on your phone. If you are calling from Europe please enter the “00” (or “+” sign if calling from a mobile device).

Step 2. Dial 1, the United States country code.

Step 3. Then enter the US area code.

Step 4. Right after the area code, dial the seven digit national telephone number you wish to call in the United States.

Here is an example: 

When calling from Europe: +1 aaa bbb bbbb (001 aaa bbb bbbb if no “+”sign)
When calling from Canada: +1 aaa bbb bbbb

The United States’ area codes are three digit long codes that are used for long-distance calling inside the country. Here are the United States area codes:

If you wish to dial a phone number with these area codes from outside United States, you would have to dial first the exit code, then the United States country code “1“.

For example, if you want to dial a phone number in Wyoming, this would be an example of a phone number: +1 307 bbb bbbb or 001 307 bbb bbbb.

Mobile phone codes in the United States are similar to the landlines phone area codes and follow the same format. The mobile phone numbers are operated by the four largest local mobile phone companies – Verizon, T-Mobile US, AT&T Mobility, Dish Wireless.

Similar to dialing a landline phone number, mobile area codes are used for dialing inside the country. When dialing a mobile phone number from outside of the country, first you need to dial the exit code (for example, “00” or “+” sign if calling from Europe), then the United States’s country code “1“, then the national telephone number including area code.

For example, if you want to dial a mobile phone number, this is what you would dial: +1 aaa bbb bbbb, where aaa is the United States area code listed in the table above.
