The country code of the USA is 1. 

There are two country codes used to call an American phone number: +1 and 001. These codes are assigned by the telecommunication system in the USA to ensure smooth communication for users for both local and international calls.


If you have been trying to call an American number and want to know what the telephone country code for the USA is,  this blog is for you. In this blog, we will discuss everything you need to know about the area and country codes in the USA. 

Country code for the USA: Overview

  • USA’s country code is 1.
  • 001 can also be used in place of +1 to dial a US-based number. 
  • If you want to call a number, after the country code, add the USA area code, which is a three-digit number and finally, the local phone number. For example, to call a friend in Manhattan, you need to dial +1212 426 XXXX from your cell phone or landline. 

What are country codes?

Country codes, ISD codes, or simply country telephone codes are the prefixes used before a telephone number of a specific region or country. These codes are defined by the International Telecommunication Union (ITU) and are used to enable international direct dialling (IDD). 


Country codes are an integral part of the telecommunications industry. They are only used at the time of dialling an international number in a region or country other than the caller’s. These codes are dialled before the actual number.

What does a USA phone number look like?

When you are in the USA and try to call a person in the USA, you need to dial the standard 10-digit mobile number. The phone numbers in America have ten digits in the format (XXX)-XXX-XXXX. Here, the first 3-digits are the area code, and the remaining 7-digits make the phone number. 


+1 or 001



USA International Code

3-Digit Area Code

7-Digit Local Phone Number


However, if you are calling from outside the USA, the number looks like this:

  • 00 – exit code for calling from outside the USA. 
  • 1 – USA’s country code is 1.
  • 3-digit area code (for ex. 202 for Washington DC)
  • 7-digit American mobile number (for ex. 939 9889 for the Indian Embassy in the USA)


Taking the above example, you need to dial 0012029399889 to call the Indian Embassy in the USA from any other country. 

How to call the USA from a landline?

Step 1: Enter the country code for the USA

The very first step is to enter the dialling code in the USA or the USA country code for the phone along with the exit code, that is, enter 001. 


Step 2: Enter the area codes for the USA

Next, enter the area code of the US region you are trying to connect to. As mentioned above, different areas or regions in the USA have different codes assigned to them. These codes are utilized in telecommunications to identify the specific region where the communication is occurring.


So, if you are trying to call in New York, you need to enter the NY area code (specific to the area in NY), i.e. 212 for Manhattan or 917 for New York City. 


Step 3: Enter the local phone number

Finally, enter the 7-digit American mobile number after the sequence. That’s all. Now, hit the call button, and you connect with a phone number in the USA.

Next, similar to the above process, enter the area code of the American city or state you are dialling to. For example, enter 206 if you are trying to call Seattle. 


Step 3: Enter the local mobile number

Now, add the seven-digit mobile number. If you are unsure about the given American mobile number, then make sure to remove any additional numbers preceding the last seven digits.

Thanks to mobile technology, it is possible to call anyone, anywhere in the world, anytime. However, the international calling feature comes at a cost, often higher than the domestic calling plans. Interestingly, there is a way by which you can call the USA for absolutely free. It is none other than the internet calling. 


If you have internet connectivity, you can call the USA or any other country without requiring an international calling plan. Some of the best platforms that enable you to call the USA for free are as follows:


WhatsApp: As we all know, WhatsApp is one of the most popular social networking applications that allows you to exchange instant messages from any part of the world. You can use the WhatsApp calling feature to call the USA for free.

Why did my call to the USA not work?

There can be multiple reasons why your call to the US is not working. Some of the most common problems are as follows:

  • Network issues: This is the most common issue behind why some people are unable to place an international call. If your mobile networks are weak, then you might not be able to make a call to the USA or anywhere else. 
  • Blocked international calling: Some mobile operators keep the blocking feature on for international calls. If this feature is enabled on your phone or other device, you cannot place a call to the USA. 
  • No international calling plan: If you don’t have an international calling plan, then you might not be able to call a USA number. You need to purchase a suitable plan for international calling. 
  • Wrong area/country code: Finally, a wrong or outdated area/country code can also stop you from calling the USA. 

What Is the Best Time to Call the USA?

  • Don’t call in the early mornings or late at night: If you are calling from a country with a different time zone than the USA, then be very careful about the timings. Refer to the USA timezone and place the call accordingly. Avoid calling very early in the morning or too late at night. 
  • Avoid calling on holidays: This tip applies to those who want to make business-related calls. Always make sure to call during the working days and working hours. 
  • Leave working hours: If you want to make a general call for any reason other than professional, then avoid calling during working hours as they might disturb the callee. 
  • Check weekdays and weekends: If you want to make a call to the USA for professional reasons, then make sure to call during the weekdays. However, for making general calls to your family or friends, weekends are recommended. 

USA – Emergency Numbers

In the United States, different emergency numbers are assigned to different types of emergencies. The primary emergency number for instant assistance is 911. 911 is an emergency number that can be used whenever you want an immediate response for medical emergencies, police, fire accidents, or any other kind of situation you need help with. 


The USA also has several other emergency numbers, as listed below:
