Yes, +1 is indeed the country code for the USA. It is an essential part of dialing phone numbers to or within the United States from an international location, and for correctly saving American contacts in your phone.
Understanding International Country Codes
An international country code, also known as an international direct dialling (IDD) code, is a telephone dialling prefix for reaching telephone subscribers in a specific country or region. Each country or group of countries typically has a unique code that must be dialled before the local telephone number. This system allows for global communication across different telecommunication networks.
For the United States, Canada, and several Caribbean nations, the country code is unified under the North American Numbering Plan (NANP), with +1 serving as the primary identifier.
The Role of +1 for the USA
The +1 country code signifies that the subsequent digits belong to a phone number within the NANP service area, which includes all 50 states of the USA, along with its territories. When you encounter a phone number beginning with +1, you can confidently identify it as an American (or Canadian/Caribbean) number.
How to Effectively Use the +1 USA Country Code
Correctly using the +1 country code is crucial for successful communication, whether you are making a call or saving a contact.
1. Dialing Phone Numbers to the USA
When you are calling a phone number located in the United States from any country outside of the NANP area, you must precede the area code and local number with the +1 country code.

Standard Format:
+1 [Area Code] [Local Phone Number]- Example: To call a New York number (area code 212, local number 555-1234), you would dial
+1 212 555 1234.
- Example: To call a New York number (area code 212, local number 555-1234), you would dial
2. Saving American Contacts in Your Phone
It's highly recommended to save all your American contacts with the +1 country code included, even if you primarily call them from within the USA. This practice ensures that their number will work correctly if you ever travel internationally and need to reach them, or if your phone's smart dialling features require it.
- Best Practice: Always store numbers like
+1 (XXX) XXX-XXXX.
3. Dialing Within the USA
If you are already within the USA, you typically do not need to dial the +1 prefix. You would usually just dial the 10-digit number (area code + local number), or sometimes even just the 7-digit local number if it's within the same area code (though 10-digit dialling is becoming standard nationwide). However, including +1 will generally not hinder the call and can sometimes simplify dialling from mobile phones.
Why +1 is Indispensable for International Communication
The consistent use of the +1 country code ensures that calls are routed correctly through the global telecommunications network. Without it, international calls to the USA would fail, as the network would not know which country the following digits belong to.
| Country/Region | Country Code |
|---|---|
| USA | +1 |
| Canada | +1 |
| Mexico | +52 |
| United Kingdom | +44 |
| Australia | +61 |
