Overview of Japan's +81 80 Mobile Prefix

The +81 80 prefix is a non-geographic mobile numbering range assigned to mobile network operators (MNOs) and mobile virtual network operators (MVNOs) in Japan. Unlike geographic area codes, which correspond to specific cities or prefectures, the 080 prefix is location-independent and used exclusively for mobile services. This means that a number beginning with 080 can belong to a subscriber anywhere in Japan, and the prefix does not indicate the caller's or callee's physical location.

Numbering Plan and Format

Japanese mobile numbers using the 080 prefix follow the ITU-T E.164 international format: +81 80 XXXX XXXX, where '81' is the country calling code for Japan, '80' is the mobile prefix, and the remaining eight digits form the subscriber number. When dialed domestically, the leading '0' is retained, so the number is dialed as 080-XXXX-XXXX. The total length of a Japanese mobile number, including the national significant number, is 11 digits (0 + 10 digits).

Assignment and Portability

The 080 prefix was introduced in 2002 to supplement the earlier 090 range due to growing mobile demand. It is shared among all major Japanese carriers, including NTT Docomo, KDDI (au), SoftBank, and Rakuten Mobile, as well as numerous MVNOs. Subscribers can retain their 080 numbers when switching carriers, thanks to Mobile Number Portability (MNP), which was implemented in Japan in 2006. As a result, the prefix no longer indicates a specific carrier.

Dialing Instructions

  • Domestic calls (within Japan): Dial the full 11-digit number, e.g., 080-1234-5678. This applies to both landline and mobile callers.
  • International calls to Japan: Dial your country's international access code (e.g., 011 from the US, 00 from most European countries), followed by Japan's country code 81, then the mobile number without the leading '0'. For example, from the US, dial 011 81 80 1234 5678.
  • International SMS and MMS: Use the same international format: +81 80 1234 5678.

Technical Considerations

080 numbers are fully integrated into Japan's PSTN and mobile networks, supporting voice, SMS, and data services. They are also reachable via VoIP services that interconnect with the public switched telephone network. Because these numbers are non-geographic, they are not tied to any specific area code, and there are no regional dialing restrictions. However, some premium or international services may have restrictions on calling mobile numbers, so it is advisable to check with your service provider.
