Everything you need to know about calling United Kingdom from Hong Kong
Connecting with friends, family, or business partners in United Kingdom from Hong Kong is straightforward when you understand the correct international dialing protocols. Whether you are calling a landline in London or a mobile phone in a remote province, this guide ensures your call connects on the first attempt.
The dialing sequence explained
To place your call, you must first signal to your local carrier that you are making an international call by dialing the Exit Code (IDD). For Hong Kong, this code is 001.
Once you have exited the local network, you must enter the Country Code (ISD) for United Kingdom, which is +44. This tells the global switching system to route your call specifically to United Kingdom's infrastructure.
Important rule on the trunk prefix
A common point of confusion is the 'Trunk Prefix'—usually a 0. In domestic calls within United Kingdom, this digit is used to signal a long-distance call. However, when calling internationally, this prefix must be omitted. If the local number you have is 012345678, you would only dial 12345678 after the country code.
Check the local time zone and scheduling considerations
Before you dial, consider the significant time difference. United Kingdom is currently 8 hours behind Hong Kong. While it might be mid-afternoon for you in Central, it could be the middle of the night in London.
Our live tracker shows that it is currently 22:33 in United Kingdom. Based on standard business hours (09:00 to 17:00), we categorize this time as Night Hours. Calling during 'Social Hours' (07:00–09:00 or 17:00–21:00) is generally acceptable for personal calls, but we recommend avoiding 'Night Hours' (21:00–07:00) unless it is an emergency.
Cost-saving tips
International carrier rates can be high. For longer conversations, consider using data-based platforms or checking with your provider for international calling bundles specifically for the Hong Kong to United Kingdom corridor. Finally, save contacts in the '+' format to avoid manual dialing in the future.
