The government plans to send the numbers to all of the approximately 55 million households in Japan by the end of November before the numbers begin in January to be used for tax, social security and disaster fields. The numbers will be written on mailed paper cards, accompanied by written applications for personal ID cards to be issued as requested by residents from January.The My Number law took effect in early October to allocate 12-digit identification numbers to everybody with resident registry in Japan, including foreign nationals, to enable tax and other authorities to discover tax evasion and wrongful receipt of welfare benefits more easily while simplifying administrative procedures for residents.''
