Hong Kong numbering plan & how to dial

Under country code +852, Hong Kong runs a closed numbering plan — just a 8-digit subscriber number after the country code, no area code required.

Hong Kong has 92% internet penetration and is served by 3 major mobile networks (HKT, SmarTone, China Mobile Hong Kong). VoIP is permitted and regulated by Office of the Communications Authority (OFCA). The local currency is HKD and the primary language is Cantonese, English, which shape IVR prompts, SMS content, and business-hours handling.

Asian markets range from fully liberalised to licensed-only VoIP, so compliant routing and correct local caller ID have an outsized effect on answer rates.

Common mistakes calling Hong Kong
  • Skipping the exit code

    Reaching Hong Kong from the US requires the 011 exit code ahead of +852 — skip it and the call won't connect.

  • Adding an area code that doesn't exist

    Hong Kong uses a closed plan — dial the +852 country code then the 8-digit subscriber number directly, with no area code.

  • Ignoring the time difference

    UTC+8 governs local business hours in Hong Kong; confirm the time there before placing the call.

VoIP Regulation

Permitted — OFCA regulated

Regulated by Office of the Communications Authority (OFCA)

  • VoIP is fully permitted and regulated by OFCA under the Telecommunications Ordinance.
  • Service-based operator licenses are required for commercial VoIP offerings.
  • Personal Data (Privacy) Ordinance mandates strict data protection for all operators.

FAQ

Calling Hong Kong — frequently asked questions

Yes. VoIP is permitted in Hong Kong, regulated by Office of the Communications Authority (OFCA), so businesses can run cloud numbers and SIP termination on compliant routes. There's no special licensing hurdle for a Twiching customer to clear before calling or texting into Hong Kong.

Yes — Hong Kong is one of 191+ countries in Twiching's directory, with virtual numbers, SIP termination, and Tier-1 routing available. It's part of the same platform used to manage numbers across every other country in the directory.

Hong Kong is the capital of Hong Kong. A local +852 number is recognisable to callers there and nationwide, which is part of why presenting local caller ID tends to improve answer rates across the whole country, not just the capital.

Cantonese, English is the primary language in Hong Kong — IVR prompts, SMS copy, and support scripts should be written in it for the best response rates. Getting the greeting and menu options right in the local language is often the difference between a caller staying on the line or hanging up.

Dial 011 (US exit code), then 852 (the Hong Kong country code), then the 8-digit subscriber number. There's no area code or trunk prefix to add in between — the subscriber number follows the country code directly.

Asian markets range from fully liberalised to licensed-only VoIP, so compliant routing and correct local caller ID have an outsized effect on answer rates. In Hong Kong specifically, that's overseen by Office of the Communications Authority (OFCA), which sets the compliance bar Twiching's routes are built to meet.
