What is Hong Kong’s Country Code?

Understanding the core numbering system ensures your international call connects on the first try.

Hong Kong’s Country Code is +852

The number 852 serves as Hong Kong’s international country calling code. The correct international format is +852 followed by the eight-digit local number. The plus sign (+) acts as the international dialing prefix notation on mobile devices, rather than an extra digit you add to the sequence. Example: +852 2XXX XXXX

This table covers conventional international dialing prefixes, not every unique carrier access code. Mobile users can generally use the plus sign (+) instead of a traditional exit code.

Does Hong Kong Have an Area Code or Leading Zero?

Hong Kong does not use separate city or regional area codes for ordinary numbers. You do not need to remove a domestic trunk prefix because standard numbers do not use one. Just dial the 8-digit number as supplied, right after the international access code and 852.

Hong Kong Mobile Number Format

Mobile numbers use eight digits. These numbers can begin with different digits. The Hong Kong Communications Authority confirms that mobile number allocations include prefixes 4, 7, and 8, alongside established ranges. Do not assume every mobile line starts with the same three digits.

Hong Kong Landline Number Format

Standard fixed-line numbers use eight digits. Landline numbers commonly start with 2 or 3. You do not need a geographic prefix for Hong Kong Island, Kowloon, or the New Territories when dialing standard numbers.

Example: +852 2XXX XXXX

Save your contacts using the international format to ensure they work anywhere in the world. Save the number as +852 followed by the complete eight-digit number, like +852 XXXX XXXX. Saving the country code helps when traveling abroad or making calls from a mobile network.
