Hong Kong Calling Code FAQ
- What is the country calling code for Hong Kong?
- +852. From abroad, dial your network’s exit code (or +), then 852, then the eight-digit Hong Kong number. Nothing is removed from the number.
- Is it +852 or 852?
- Same code. +852 is the portable form for contacts and mobiles; 852 is what follows an origin exit prefix (for example 011 852… from the US, or 00 852… from the UK). Do not store the origin exit digits as part of the destination.
- Do I drop a leading 0?
- No. Hong Kong has no domestic trunk prefix, so there is no 0 to remove and none to add: 2XXX XXXX becomes +852 2XXX XXXX. Don’t apply mainland China’s fixed-line trunk-0 rule to Hong Kong numbers.
- How do I dial a Hong Kong mobile or landline from abroad?
- The same way for both. From the US: 011 852 9XXX XXXX. From the UK: 00 852 9XXX XXXX. From any mobile: +852 9XXX XXXX. Landlines work the same way with 2XXX XXXX; there is no city code to add.
- Is +852 the same as China +86 or Macao +853?
- No. Mainland China is +86; Macao is +853; Hong Kong is +852. Using +86 for a Hong Kong number is a common formatting mistake.
How to Dial Hong Kong
Saving the number in contacts
Start with +852, then use the reviewed national significant number. There is no domestic trunk prefix; keep all eight digits after +852.
Calling from abroad
On a mobile, use the + form. If a network requires digits instead, replace + with that origin network's international prefix. Hong Kong's own standard exit prefix for outbound calls is 001.
Special Administrative Region of China. No area codes.

Exceptions and Routing Notes
Common Hong Kong Formatting Mistakes
- Using mainland China’s +86 for a Hong Kong number.
- Adding a 0 after +852 by copying a trunk-0 habit from another country.
- Saving an exit code (001, 011 or 00) as part of the contact.
Number Portability and Carrier Data
Mobile number portability means a prefix may not identify the current carrier. Treat carrier data as a timestamped lookup result, not a permanent property of the number.
