The Hong Kong country code is +852 — reaching all 7.5 million Hong Kongers + ~21 million mobile subscriptions across CSL Mobile (HKT/PCCW), 3 Hong Kong, China Mobile HK + SmarTone. Asia\'s premier financial center + one of the world\'s most international cities.
Hong Kong was assigned +852 by the ITU in 1964 (when it was still a British colony — Hong Kong kept the same code after the 1997 handover to China). Hong Kong sits in ITU zone 8 alongside China +86, South Korea +82 + Vietnam +84. Hong Kong uses a closed 8-digit numbering plan.
Hong Kong has used the +852 country code since 1964, in zone 8 alongside China +86 (mainland), South Korea +82 + Macau +853 (its sister SAR). Hong Kong's +852 was preserved unchanged when sovereignty transferred to China in 1997 under the "One Country, Two Systems" framework.
Hong Kong's telecom regulator is OFCA (Office of the Communications Authority — part of the Communications Authority). Four major mobile carriers operate: CSL Mobile (the largest, owned by HKT/PCCW, ~5M subs), 3 Hong Kong (CK Hutchison's carrier, ~4M), China Mobile Hong Kong (~3.5M) + SmarTone (~2.5M, Sun Hung Kai-owned).
Hong Kong uses a closed numbering plan: every HK number is exactly 8 digits. The first digit tells you the type: <b>2</b> + <b>3</b> landline + VoIP, <b>5</b>, <b>6</b>, <b>9</b> mobile, <b>7</b> pagers (mostly retired), <b>8</b> services + toll-free, <b>4</b> reserved. Same number works throughout HK's territory.
One of the world\'s top 3 financial centers. Hong Kong consistently ranks among the top 3 global financial centers (alongside New York + London). HKEX (Hong Kong Stock Exchange) is among the world\'s top 10 by market cap + handles the most IPOs globally in many years. HSBC + Standard Chartered + every major global bank run their Asia-Pacific HQ here. Hong Kong is the gateway to mainland China business under "One Country, Two Systems". A +852 line is the natural caller-ID for any business serving Greater China + global finance.
A Hong Kong phone number in international format is written as +852 [8-digit number]. No area code, no leading 0. Example: +852 2123 4567 for a landline, +852 9123 4567 for a mobile, +852 3123 4567 for a VoIP line.
The first digit of every Hong Kong number is a type indicator. 2 is the legacy landline range (PCCW + most fixed lines). 3 is newer landline + VoIP. 5, 6, 9 are mobile (number-portable since 1999 — you can\'t reliably tell the carrier from the prefix). 8 is toll-free + services. All numbers are 8 digits.
From Central's skyscrapers to Tsim Sha Tsui's Star Ferry to the New Territories, every Hong Kong number lives behind a +852. With no area codes, a single 8-digit number works city-wide.
Every country uses a different exit code before +852 Hong Kong. From any mobile, + replaces the exit code — so +852 2123 4567 works worldwide. No leading 0 to drop, no area code to handle.
