Resident Registration Number

A resident registration number (Korean: 주민등록번호 Jumin Deungrok Beonho, Hanja: 住民登錄番號) is a 13-digit number issued to all residents of the Republic of Korea. Similar to national identification numbers in other countries, it is used to identify people in various private transactions such as in banking and employment. It is also used extensively for online identification purposes. But original usage of this number was discovering North Korean spy, after the Blue House Raid. Remained from this, all Korean who have the number registered their fingerprint to government(Fingerprint is printed at backside of every Resident registration number card).

Upon registration with their city office, foreigners (except those affiliated with the U.S. military) receive an alien registration number, which serves as a substitute, on their alien registration card.

Famous quotes containing the word number:

    If we remembered everything, we should on most occasions be as ill off as if we remembered nothing. It would take us as long to recall a space of time as it took the original time to elapse, and we should never get ahead with our thinking. All recollected times undergo, accordingly, what M. Ribot calls foreshortening; and this foreshortening is due to the omission of an enormous number of facts which filled them.
    William James (1842–1910)
