Japanese Mobile Number Structure (+81)
In Japan, mobile phone numbers are strictly regulated. A standard mobile number consists of an 11-digit string. When represented internationally, it starts with the country code +81, followed by the mobile prefix (dropping the leading '0').
| Type | Format | Common Prefixes |
|---|---|---|
| Mobile | +81 70/80/90-XXXX-XXXX | 070, 080, 090 |
| IP Phone | +81 50-XXXX-XXXX | 050 |
Famous Japanese Mobile Prefixes
Understanding the prefixes helps in identifying the type of service in Japan:
- 090 & 080: The most traditional and widely used mobile prefixes.
- 070: Originally for PHS (Personal Handy-phone System), now used for all mobile services.
- 050: Assigned to VoIP and IP-based phone services.
