Hong Kong phone numbers — common questions
What is the country code for Hong Kong?
The international dialling code for Hong Kong is +852. A virtual Hong Kong 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 Hong Kong 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 Hong Kong 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.
