How to Call Hong Kong from the US — Country Code +852
Hong Kong's country code is 852 (also written as +852 or 00852). To call Hong Kong from the United States, dial 011 + 852 + area code + local number from a US landline, or +852 + area code + local number from a mobile phone. Drop the leading 0 from the local number. Kinvo connects any Hong Kong number from your browser at $0.22/min — no app, no subscription. For the dialing code itself and number-format reference, see the Hong Kong country code page.
Hong Kong has no area codes — every number is a flat 8 digits. Landlines start with 2 or 3, and mobiles start with 5, 6, or 9. To call Hong Kong from abroad, dial +852 followed directly by the 8-digit number. There is no trunk prefix to drop.

How to Call Hong Kong From iPhone, Android, or a Landline
From an iPhone
Open the Phone app, press and hold 0 until a + appears, then type 852 followed by the local Hong Kong number. Or use Kinvo in Safari — no dialer permissions needed.
From Android
Open your Phone app, long-press 0 to get +, then dial +852 + the number. In Chrome, open kinvophone.com and call directly without touching your carrier plan.
From a US Landline
Landlines don't have a + key, so use the full exit code: 011 852 then the local number. Check with your phone provider that international calling is enabled to avoid blocked calls.
How to Call Hong Kong For Free
If the person you're calling in Hong Kong has a smartphone with internet access, the cheapest way to call them is free: use WhatsApp, FaceTime, Telegram, Signal, or Google Meet. Both sides need the same app, and calls travel over the internet rather than the phone network — no per-minute fees, no country code needed.
For calling any regular Hong Kong landline or mobile number — the kind that requires dialing +852 — there is no truly free option, because someone has to pay the termination fee to connect the call. Kinvo is the lowest-cost option for dialing Hong Kong phone numbers, starting at $0.22/min with no subscription, compared to $1–$3/min at most US carrier rates.
Hong Kong Calling Tips
Hong Kong numbers are 8 digits with no area codes. Landline numbers start with 2 or 3. Mobile numbers start with 5, 6, 7, or 9. Dial +852 followed by the 8-digit number. Cantonese is the primary language, with English also official. Excellent telecom infrastructure.
Why Calls to Hong Kong Sometimes Fail (and How to Fix Them)
When a call to Hong Kong doesn't go through, the cause is almost always one of four issues — not the network. The most common is forgetting to drop the leading 0 from the local number after entering +852. Domestic Hong Kong numbers are written with that 0 at the start; that 0 is the trunk prefix and has no role in international dialing. Dial +852 XX directly, with no 0 in between.
The second is using the wrong exit code from the US. The North American Numbering Plan uses 011 — not 00, which is the international exit code most European countries use, and not the + sign on a landline (which has no + key). From a US mobile, holding the 0 key produces +; that's functionally identical to dialing 011 and works on any GSM or CDMA network worldwide. The third is dialing while your US carrier's international calling is disabled — some pre-paid plans block outbound international calls by default, and you need to call your carrier to enable it (often free, sometimes a small monthly add-on). The fourth is mistaking a +852 number for a fixed-line when it's a mobile or vice versa — the rate difference can be 2-5x, so confirm the number type before long calls.
Hong Kong's domestic time zone matters for whether anyone picks up. Most Hong Kong households answer between roughly 8 AM and 9 PM local time; for US callers, 7 pm–11 pm us eastern (previous day) = 8 am–12 pm next day in hong kong (hk is utc+8 year-round, no dst) tends to be the best window.Government offices, banks, and most businesses observe local public holidays and may close early on the day before a major holiday — calls placed during those windows will go to voicemail or unanswered ring regardless of dialing format.
On cost: a 30-minute call to Hong Kong via direct-dial from AT&T, Verizon, or T-Mobile costs $30–$90 depending on whether you have an international add-on. The same call through Kinvo costs $6.65 with no monthly fee. WiFi calling on your phone routes the call through your carrier and bills at carrier rates — it does not save you money on international calls (see WiFi calling vs VoIP).
