Hong Kong phone numbers
5123 4567
International +852 5123 4567, E.164 +85251234567
The numbering plan of Hong Kong: formats, lengths, the regular expression for each line type and the prefix blocks allocated to each carrier, as ITU publishes it. A pattern says what a number looks like and where it was allocated; whether it is in service, and who serves it today, is a different question (below).

Test a pattern
Tick the line types you accept, copy the combined pattern, and paste numbers to see which range each one falls in. Numbers are reduced to their national digits first (no spaces, no +852, no trunk prefix); nothing leaves your browser.

Walk the prefixes
Type the first digits of a number in national form, or tap them: the operators holding blocks under those digits, then the block a full prefix falls in. 447 blocks held by 14 operators are on record.

The operator each prefix block was allocated to, in national form, from the published allocation records for +852. Numbers are portable, so this is the original allocation, not necessarily the carrier serving a number today.

Questions developers ask
- How many digits does a phone number in Hong Kong have?
- Mobile numbers have 8 national digits. Fixed line numbers have 8 national digits. That is the national number, without the country code +852.
- What is the country code for Hong Kong?
- +852. From abroad, dial your own exit code, then 852, then the national number. From inside Hong Kong, the exit code for international calls is 00.
- Which prefixes are mobile numbers in Hong Kong?
- Mobile numbers start with 4, 5, 6, 7, 8 or 9 in national form; the mobile regular expression on this page gives the exact ranges (example: 5123 4567). The carrier table shows which prefix blocks were allocated to which operator.
- Can a mobile number in Hong Kong be ported to another carrier?
- Yes. Hong Kong has mobile number portability, so a prefix tells you the carrier a number was originally allocated to, not necessarily the one serving it today. Only a live carrier lookup (an HLR or MNP query) answers that.
