FreJun makes calling the USA from Japan simple and affordable, offering low-cost international rates, exceptional call clarity, and seamless CRM integration. Its cloud-based system provides real-time analytics, call tracking, and reliable connectivity, helping businesses optimize communication effortlessly.

What is the Dialing Format?

When making an international call from Japan to the United States, the dialing sequence typically includes the following components:

• Japan’s international access code: 81
• United States country code: 1
• Area code: A 3-digit code specific to the region within the US.
• Local phone number: A 7-digit unique identifier.

Example:

If you are calling a number in New York with the area code 212 and the local number 555-1234, the dialing sequence will look like this:

81-1-212-555-1234

To break this down:

• 81 initiates the international call from Japan.
• 1 is the United States’ designated country code.
• 212 represents the area code for New York City.
• 555-1234 is the specific local number of the recipient.

What is the Steps of Dialing Process

1. Dial the International Access Code

• Begin by entering Japan’s international access code: 81.
• This code acts as a gateway, allowing you to initiate calls to foreign countries.
• Without this step, your call will not be recognized as international and may not connect.

2. Add the US Country Code

• After dialing 81, input the United States country code: 1.
• Alternatively, some phones allow you to use a + sign instead of the international access code. To do this, hold down the 0 key until the + symbol appears. For example, you can dial +1 followed by the rest of the number.

3. Input the Area Code

• The area code is a 3-digit number corresponding to a specific region in the United States.
• Each state has multiple area codes. For instance:
  • California’s area codes include 213, 310, and 415.
  • Texas uses area codes like 214, 512, and 713.
• Research the correct area code for your contact’s location to ensure accurate dialing.

4. Complete with the Local Number

• Finally, enter the 7-digit local number of your contact.
• Double-check the entire number to avoid dialing errors, which can result in failed calls or connecting to the wrong person.

How do I Call the USA using Landline vs Mobile vs VoIP from Japan?

These are the ways of Calling From Different Devices:

81-1-[area code]-[local number]

Tips for landline calls:

• Be mindful of time zones to avoid calling at inconvenient hours.
• Ensure you have a clear line to prevent disruptions.
• If you’re using a business landline, check for restrictions or additional codes required for international calls.

2. Mobile Phones

Most mobile phones support the use of the + symbol for international calls. To enter +, hold down the 0 key on your dial pad.

Example: +1-212-555-1234

Key considerations for mobile calls:

• Some carriers may charge additional fees for international calls, so it’s wise to check your plan beforehand.
• Many mobile plans offer international calling packages that significantly reduce costs.
