852 Country Code: Hong Kong (+852)
Country code 852 (+852) belongs to Hong Kong. Hong Kong uses the international dialing code +852, assigned by the International Telecommunication Union (ITU) under the E.164 standard. The ISO 3166-1 alpha-2 code is HK.
You will see the same code written several ways depending on origin: +852 (universal + prefix, works from mobile), 00852 (from countries that use 00 as their international exit code — most of Europe, Asia, and Latin America), 011 852 (from the US and Canada), 0011 852 (from Australia), or the bare 852. All refer to the same Hong Kong country code. Note: 852 is not a US area code — US area codes are also 3 digits but +852 is the international dialing code for Hong Kong, not a domestic US destination.
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.

Calling Hong Kong Successfully: Common Mistakes & Best Practices
Most failed calls to Hong Kong come from one of four mistakes, not from network problems. The most common is mishandling the country code itself: Hong Kong uses +852 with no trunk prefix to remove, so you dial it as-is. The most frequent error is adding a leading 0 by habit — there is none in the Hong Kong number plan.
The second is misreading the area code on landline numbers — Hong Kong numbers may have variable formatting depending on the carrier and city, so confirm the area code with the recipient before dialing. The third is dialing during off-hours — Hong Kong uses Cantonese business hours and consumer phones are usually answered between 8 AM and 9 PM local time. The fourth and most expensive mistake is assuming your US carrier's WiFi calling feature makes the call cheap. It does not — see WiFi calling vs VoIP for international calls for why.
For scam-call awareness: +852 is the legitimate Hong Kong country code, and most unsolicited calls from +852 numbers are legitimate calls from Hong Kong-based businesses, hospitals, family members, or call centers serving US customers. Caller-ID spoofing exists, so if a call from a +852 number claims to be from a US government agency, your bank, or the IRS, hang up and call the agency back on its published number. Real authorities never demand payment over the phone.
