Calls, SMS and WhatsApp on one number

Japan phone numbers — common questions
What is the country code for Japan?
The international dialling code for Japan is +81. A virtual Japan number is issued inside that numbering plan, so it appears as a local number to anyone calling or texting from within the country.
Can I receive SMS on a Japan number?
Yes. Incoming SMS arrives instantly and can be read in the platform, delivered into 3CX, or pushed to your own server through a real-time webhook. Two-way conversations run on the same number.
Do I need an office in Japan to get the number?
No. The number is virtual — it routes to your existing 3CX system or SIP setup wherever your team works. You manage it from the browser.
Can I use a Japan number for calls as well as SMS?
Yes. The number handles inbound and outbound calls plus SMS in both directions, and can also receive WhatsApp audio and video calls routed into your system.
