Telephone numbers in Hong Kong are mostly eight-digit. Fixed land line numbers start with 2 or 3, mobile (cellular) phone numbers with 5, 6, 7 or 9, pager numbers with 7 and forwarding service with 8. Since the end of 1989, there have been no area codes within Hong Kong.


The telephone number for emergency services – Police, Fire Service and Ambulance – is 999 for all telephone lines. These numbers can also be used for mobile and other users:

Some special numbers are three- to five-digit. Some premium rate services, for example for games and adult contents, are 11-digit. Numbers beginning with '1' are usually reserved for carrier/operator services. These services are provided by the individual telephone carrier. In general, these numbers can be used across all carriers:

The international call prefix varies depending on IDD provider, however 001 works on all phone lines and uses the IDD service provided by the same carrier as the telephone line that 001 call is dialed from. During the years of telephone monopoly, the International call prefix was 106 (through 1980s) and then 001. Calls to Macau and mainland China are international, as are calls to Taiwan. Calls from Hong Kong to other parts of China include that regions separate country code:

Historical numbering scheme and area codes


In the 1970s, area codes were assigned with the following pattern:

There was no standard trunk prefix like '0' – only the area code and phone number were dialed when calling from one area code to another. Thus the Kowloon number xxx-xxx would have been dialed as follows:


In the mid-1980s, 6-digit numbers starting with '0' became 7-digit numbers starting with '71', making way for subsequent change of the New Territories prefix from '12' to '0'.

Fixed-line phone numbers were either six- or seven-digit in the 1980s. Area codes were assigned with the following patterns.

Cellular phone numbers are all eight-digit starting with '9'.

Easy Dialling Day

On 30 December 1989, area codes were abolished. [3] Six-digit numbers in the New Territories were changed to replace the initial 8 with 46, followed by five digits; area codes for six-digit numbers in the other areas became part of subscriber's numbers. Area codes for seven-digit numbers were simply removed. Some six-digit numbers had the first digit changed to two digits to make a seven-digit number.


On January 1, 1995, [4] a '2' was prefixed to all fixed line (land line) numbers which are now eight-digit. A '7' was prefixed to existing pager service numbers.

Since 2000s

Before the introduction of portable fixed line numbers, numbers were assigned in a pattern akin to districts. For example, in addition to the existing 3, 5 and 0 prefixes, a 4 prefix was used for Tuen Mun and Yuen Long, 6 for Tai Po and Sha Tin, and 8 for Hong Kong Island.

Numbers starting with '3' were introduced when '2' for fixed lines started running out. Cell phone numbers remain eight-digit. The number '6' started to be used when numbers started with '9' were running out. In May 2008, cellular phone numbers with '5' as the beginning were also introduced.

Due to numerous phone scams spoofing local telephone numbers, calls started from outside Hong Kong using a local number now show the Hong Kong prefix +852 before the phone numbers in Caller ID. [5]

Premium-rate telephone numbers are telephone numbers for telephone calls during which certain services are provided, and for which prices higher than normal are charged. Unlike a normal call, part of the call charge is paid to the service provider, thus enabling businesses to be funded via the calls. While the billing is different, calls are usually routed the same way they are for a toll-free telephone number, being anywhere despite the area code used. These telephone numbers are usually allocated from a national telephone numbering plan in such a way that they are easily distinguished from other numbers. Telephone companies typically offer blocking services to allow telephone customers to prevent access to these number ranges from their telephones. In some jurisdictions, telephone companies are required by law to offer such blocking.

A toll-free telephone number or freephone number is a telephone number that is billed for all arriving calls instead of incurring charges to the originating telephone subscriber. For the calling party, a call to a toll-free number from a landline is free of charge.

A telephone numbering plan is a type of numbering scheme used in telecommunication to assign telephone numbers to subscriber telephones or other telephony endpoints. Telephone numbers are the addresses of participants in a telephone network, reachable by a system of destination code routing. Telephone numbering plans are defined in each of the administrative regions of the public switched telephone network (PSTN) and in private telephone networks.

Telephone numbers in the United Kingdom have a flexible structure that reflects their historical demands, starting from many independent companies through a nationalised near-monopoly, to a system that supports many different services, including cellular phones, which were not envisaged when the system was first built. Numbers evolved in a piecemeal fashion, with numbers initially allocated on an exchange-by-exchange basis for calls connected by manual operators. Subscriber numbers reflected demand in each area, with single digit telephone numbers in very rural areas and longer numbers in cities.
