The numbering plan of Japan: 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 +81, no trunk prefix 0); 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. 245 blocks held by 5 operators are on record.

The operator each prefix block was allocated to, in national form, from the published allocation records for +81. 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 Japan have?
- Mobile numbers have 10 national digits. Fixed line numbers have 9 national digits. That is the national number, without the country code +81 and without the trunk prefix 0.
- What is the country code for Japan?
- +81. From abroad, dial your own exit code, then 81, then the national number without its trunk prefix 0. From inside Japan, the exit code for international calls is 010.
- Which prefixes are mobile numbers in Japan?
- Mobile numbers start with 060, 070, 080 or 090 in national form; the mobile regular expression on this page gives the exact ranges (example: 090-1234-5678). The carrier table shows which prefix blocks were allocated to which operator.
- Can a mobile number in Japan be ported to another carrier?
- Yes. Japan 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.
