Nowadays, making a phone call to the United States is very simple. However, you need to have the correct US prefix phone number, as over 300 area codes are spread across the states. When calling someone in the US, you must learn how to write a US phone number with the country code. If you are unsure about the US phone number country code format, this article will help you through.

How to call the USA using your phone?

Similar to other countries, the US phone number country code format has its format. When you dial it, you’re calling that country’s area code from abroad. Follow these steps if you don’t know how to write a US phone number or are unaware of the US country code phone number format.

1. Obtain the country’s international exit code

The country’s exit code helps you dial a US number from your landline or cell phone. Enter the USA exit code before doing anything else.

 To call abroad to the US, use below two ways to dial the exit code:

  • +1
  • 001

2. Know the country code for the USA

What is the country code for US phone numbers? Well, the USA country code is 1. The code allows you to call the US from outside of the USA.

A country code comprises 1 or 2 digits. One needs to dial the country code after the exit code. For example “001”+”1” 

 3. Check the correct area code

An area code is defined geographically and refers to a specific city. US phone numbers are processed by a three-digit area code. Here’s the international code for a US phone number. 


4. Double-check the local phone number 

The US prefix phone number consists of 7 digits long. If you’re calling a business, you likely need to check the phone number online before dialing. 

5. Know the complete US phone number format with country code

The order of the number will be the country exit code ->+1 (US country code) -> area code -> 7-digit local phone number.

For example, if you’re calling New York City, your US phone number country code format will look like this: 010 1 718 222 2222

Whether you are calling a friend living in your street or doing business in a different state, all you need is a US country code phone number format that includes a three-digit area code.

  • You dialed the wrong area code.
  • You haven’t checked the phone number that accepts international calling or not.

With time, due to the popularity of text-based and other communication options have risen, voicemail still has some usage. But the common use of voicemail is checking the message after not responding from an unknown number.

3. Is 001 the US country code? 

Country calling codes are called prefix codes. The prefix for phone numbers in the US is 1. Moreover, it depends on where you’re dialing it. 00 is the exit code or prefix code for India, which is used before making an international phone call. While ‘1’ is the country code for the United States. Then how to add the US country code to the phone? 

If you are dialing from a cell phone, you can use 00 as an alternative to +. This + sign is usually located on the 0-digit key. Click and hold the key until the 0 switch turns +. Now, one can continue to dial the country code and telephone number.

For example, it looks like this: +1 (222) 222-2222

4. How much does it cost to call a US number?

A few countries have different procedures for calling a mobile phone number. This may cost more if you’re calling a US cell phone other than a landline. Ask your service provider about the dialing process and its rates if you want to call a number.

Else consider calling through a landline phone as it may cost less than a mobile phone. And, if you don’t want to consider any of these options, try signing up for an international plan through VoIP phone number services like CallHippo. It offers an excellent solution for businesses looking to make hundreds of calls internationally at a low cost.
