Random Japan Phone Number Generator Rules
The rules are based on Japan’s MIC numbering plan. A Japan phone number uses trunk prefix ‘0’ domestically or +81 internationally. Formats include geographic (e.g., 03-XXXX-XXXX) and mobile (e.g., 090-XXXX-XXXX). Our generator follows these constraints to create realistic Random Phone Numbers for testing.
Area Code (市外局番) rules:
- Domestic numbers start with trunk prefix ‘0’. Omit ‘0’ and add +81 for international format.
- Geographic area codes are 1–4 digits after ‘0’ (e.g., 03 Tokyo, 06 Osaka, 011 Sapporo, 075 Kyoto).
- Mobile prefixes are 070, 080, or 090. IP telephony uses 050. Toll-free 0120 and shared-cost 0570 are reserved.
Central Office Code (局番/Prefix) rules:
- For geographic numbers, the exchange (局番) length varies so that total digits with the leading ‘0’ equal 10 (e.g., 03-XXXX-XXXX or 011-XXX-XXXX).
- For mobile/IP numbers, total digits with the leading ‘0’ equal 11 (e.g., 090-XXXX-XXXX, 050-XXXX-XXXX).
- Digits are 0–9; avoid service codes and short codes (e.g., 1XY emergency/service numbers).
- Avoid obviously invalid sequences like all zeros within the block.
Subscriber Number (加入者番号) rules:
- Subscriber blocks are numeric 0–9.
- Typical formats: geographic 4+4 or 3+4 after area/exchange; mobile/IP use 4+4.
- Avoid all-zero and all-nine combinations for realism.
