ABSTRACT
This article suggests the use of a single identity number as a primary key to open other identification, such as a driver’s license and family card. This is because so many identity cards issued by institutions in Indonesia have fields that are of the same data, such as name, address, and birth date. The numerous forms of citizen identification imply minimum citizenship data integrity, and there is also no identity guarantee validation. This has resulted in problems of inconsistencies and unsynchronized data in the use of identity cards. There is a policy to implement a single identity number to integrate existing identity numbers. The method is to create a main server as data storage and to observe some key data to link all collected data. Ultimately, the single identity number can be used for all purposes, both for the country and the citizens.
