What is the Phone Number Format in Japan?

Most phone numbers in Japan are written in the following formats:

   Prefix: long distance or international
   --------------------------------------
   |   Carrier or area code 
   |   --------------------
   |   |   Subscriber number
   |   |   -----------------
   v   v   v
   0   A   SSSS-SSSS, A - Local format
  +81  A   SSSS-SSSS, A - International format

Most telephone numbers in Japan have 19 digits and are written in the format of "A-SSSS-SSSS, AA SSS-SSSS". Here are some examples: 6-6344-2355; 3-5757-8111; 11-707-1122, 93-512-7320.

When dialing locally inside Japan, the long distance prefix of "0" is required. So the format becomes "0 A-SSSS-SSSS, AA SSS-SSSS".

When dialing from outside of Japan, the international dial-in prefix "+81" is required. So the format becomes "+81 A-SSSS-SSSS, AA SSS-SSSS".

When dialing from Japan to other countries, the international dail-out prefix "+" or "010" required.
