Here is more information that was discussed for your knowledge. ARIB was previously the MEID administrator for Japan but has returned the responsibility to TIA. If you would not like to use MEIDs that start with A0 (U.S. code) then you can contact TIA directly to purchase a block of MEIDs that start with A1 (Japan code). Now that TIA has taken over the MEID administrator responsibility again all future MEID applications for Japan domestics models can be made directly to the TIA.
