The history behind Japanese phone numbers

The history of Japan's phone numbers can be traced back to the late 19th century when the country's first telegraph service was introduced in 1869. However, it wasn't until the 1890s that Japan's first telephone exchange was established in Tokyo.

Initially, telephone numbers in Japan consisted of a combination of letters and numbers. For example, the first telephone exchange in Tokyo used the letters "AD" to represent the number 1, "BD" for 2, and so on.

In 1921, Japan switched to a purely numerical system for telephone numbers. At the time, phone numbers in Tokyo consisted of four digits, while numbers in other parts of the country had three digits. The first digit of a Tokyo phone number indicated the exchange, while the remaining digits indicated the subscriber's number.

Over the years, Japan's telephone system has undergone several changes and improvements. In 1958, Japan introduced the "direct dialing" system, which allowed people to make long-distance calls without the assistance of an operator. In 1978, the country introduced the "Area Mail Handling System," which allowed for faster and more efficient routing of telephone calls.

Technical info on Japanese phone numbers

In Japan, phone numbers consist of 10 digits and are structured into three groups: the area code, the city code, and the subscriber number. The area code is a 2 or 3 digit number that identifies the region of the country, while the city code is a 1 or 2 digit number that specifies the city or district within that region. The subscriber number is a 4 or 5 digit number assigned to each individual phone line.

To call a phone number in Japan from overseas, you must first dial the country code, which is +81, followed by the area code and the subscriber number. Some mobile phone numbers in Japan may begin with the prefix "080" or "090," which indicate the type of mobile service provider.

The government agency in charge of phone numbers in Japan is the Ministry of Internal Affairs and Communications (MIC). They oversee the allocation and management of phone numbers and other communication-related resources in the country. There were major changes to the way the country handles VoIP phone numbers in late 2022/early 2023.
