Japanese Mobiles to get 070 prefix from November 2013

Japan uses preallocated prefixes for particular types of phone numbers. Currently, 090 and 080 numbers are reserved for mobile phones, 070 is for PHS, and 050 is for a particular type of IP Phone.

At first, mobiles used only 090 with additional prefixes allocated as needed, starting with 080 in around 2005 and now 070. Only a portion of 070 will be used for mobile; a chunk of numbers will remain PHS.
  • Mobile: 070-1 to 4 and 070-7 to 9
  • PHS: 070-5 and 6
However, the MIC is considering to allow portability of numbers between PHS and mobiles. It will then not be possible to tell the difference based on the number alone. Plans call for a specific initial ringtone to denote if the destination is PHS. This will be provided by Wilcom, the only PHS provider by November 2013.
