A:The Corporate Number is a 13-digit number which is designated per corporation by the Japan National Tax Agency in order to identify a specific corporation or other organizations. The Number is used for administrative procedures such as social security, tax, and disaster control.
In foreign countries, the numbers called Tax Number and Tax ID are used. However, the systems differ among countries in terms of the use ranges and purposes.
Therefore, it cannot be said generally that the Corporate Number is the same as the Tax Number used in each country. If the Tax Number generally means a number used for tax-related procedures, it is also a number to be described in tax-related documents in order to identify a specific corporation or other organizations. From the above, it seems that the Corporate Number can be used as the Tax number.
