Hong Kong at a glance
The numbers and facts you need before you dial.
What is the country code for Hong Kong?
+852 is the code that puts you through to Hong Kong. What makes the territory unusual is what comes after it: a single flat block of 8 digits, no area codes, no district splits. The plan has worked this way since 1989, so whether you're calling a bank in Central or a flat in Sha Tin, the international number is identical in shape — +852 plus those 8 digits, full stop.
Code +852 was assigned to Hong Kong by the ITU under the E.164 plan. The “+” means “dial your local international exit code”; on a mobile, press and hold 0 to type it.
All four mean the same thing — they connect your call to Hong Kong.
How to call Hong Kong from anywhere
Three pieces and you're through: your exit code, then 852, then the 8 digits exactly as printed. No trunk 0 to remember, no area code to look up — a rare luxury for international dialing.
Full example: +852 22345678 XXX XXXX — drop the local leading 0 when calling from abroad.
Hong Kong phone number format explained
With no districts to encode, Hong Kong lets the very first digit do the sorting. Every number is exactly 8 digits, and that opening digit tells you the line type at a glance: 2 or 3 means a fixed line, while 5, 6, or 9 (and the newer 4, 7, 8 ranges) mark a mobile. No prefix archaeology required.
Landline
8 digits starting with 2 or 3 (e.g., +852 2234 5678). No area code is dialed.
Mobile
8 digits starting with 5, 6, or 9 — plus newer 4, 7, 8 mobile ranges (e.g., +852 9123 4567).

Hong Kong mobile network prefixes
The prefix after +852 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.

Hong Kong time zone
Hong Kong runs on Hong Kong Time (HKT), UTC+8, and never touches the clocks — no daylight saving means the offset you learn today holds in July and in December alike. For a 24-hour finance hub, a fixed offset is a feature, not a footnote.
US callers catch the Hong Kong trading desk by dialing in their own early morning, which lands mid-afternoon HKT. UK and European teams have it easier — a late-morning call reaches Hong Kong's afternoon or early evening. And because Singapore and mainland China share the hour, a single 9-to-5 HKT window covers the region's three biggest markets at once.

Common mistakes when calling Hong Kong
Almost every failed international call is a formatting issue, not a network issue.
Treating +852 as if it were mainland China
it isn't. Hong Kong keeps its own code; the mainland is +86. A Shenzhen office sits minutes across the border yet needs a completely different prefix, and mixing the two is the single most common Hong Kong dialing error.
Adding an area code
there are none; dial just the 8 digits after +852.
Inserting a trunk 0
Hong Kong has no national trunk prefix to drop or add.
Sending only 7 digits
every Hong Kong number is exactly 8.
Reading the carrier off the leading digit
number portability means a "5" or "9" tells you nothing reliable about the current network.
Tips to reduce the cost of calling Hong Kong
Move traffic onto VoIP or a virtual number to turn IDD tariffs into local-rate calling.
Favour fixed lines (2/3) when you have the choice
they often cost less to terminate than mobiles.
Place calls inside HKT business hours so you connect first time instead of paying for repeat attempts.

Hong Kong +852 — FAQ
Is +852 the same as China's +86?expand_more
— No, and this trips up a lot of callers. Hong Kong has its own dedicated code, +852; mainland China is +86. They're separate networks even though the border is a short ride away.
Why doesn't Hong Kong have area codes?expand_more
— It dropped them in 1989 in favour of a single flat 8-digit plan, so the same number works whether the line is on Hong Kong Island or in the New Territories.
How do I tell a Hong Kong mobile from a landline?expand_more
— Read the first digit: 5, 6, or 9 (and newer 4, 7, 8) signal a mobile, while 2 or 3 signal a fixed line.
Do I add a 0 or a trunk prefix when calling Hong Kong?expand_more
— No. There's no trunk 0 — dial your exit code, 852, then the 8 digits exactly.
How many digits should a Hong Kong number have?expand_more
— Always 8 after +852. Seven means a digit went missing.
Can I tell which carrier a Hong Kong number is on?expand_more
— Not from the digits. Number portability lets subscribers keep their number across CMHK, CSL, 3, and SmarTone.
Does Hong Kong change its clocks for summer?expand_more
— Never. It stays on HKT (UTC+8) all year, which keeps it permanently aligned with Singapore and mainland China.
Can my business get a Hong Kong number without an office there?expand_more
— Yes — MCM provisions genuine +852 virtual numbers and routes the calls to your team anywhere.
