Central Registration Number () is used by the Indonesian National Armed Forces as the primary means of service member identification. Background After the Indonesian National Revolution has ended, there were no methods to identify official members of the Indonesian Armed Forces. A lot of rogues and street warriors claimed themselves as the member of the armed forces, which caused confusion among commanders.

Major General Bambang Sugeng, as the Chief of Staff of the Indonesian Army began the first attempts at creating an identification numbers for members of the Indonesian Army. He order regional commanders to enlist their troops. As a result, 88,324 members of the Indonesian Army were officially recorded.

Soon, the other forces, such as the Indonesian Navy and Indonesian Air Force followed suit.
