# Household registration in Taiwan

Household registration (Chinese: 戶籍; pinyin: hùjí; Pe̍h-ōe-jī: hō͘-che̍k) is a Taiwanese civil and family registration system. The modern household registration system was started in early 20th century when Taiwan was under Japanese rule. Currently the system is administered by the Ministry of the Interior. Under Taiwanese law, household registration guarantees an individual the right of abode in Taiwan, and the ability to fully exercise their civil and political rights, such as the right to vote. Thus, the term national with household registration is sometimes used to refer to a citizen in official documents.

## History

Early forms of household registration was first established in Dutch Formosa in 1647 by the Dutch East India Company. Later regimes including Kingdom of Tungning and the Qing Taiwan administration maintain similar registers on local family profiles of the Taiwanese people. In these eras, registers on families were also used to organize Taiwanese people to conduct civil defense, known as the Hoko system. The system existed until the era of Japanese rule.
In the early 20th century during Japanese rule, the Government-General of Taiwan started to build very thorough household registration records for both families and persons, like the Koseki system implemented in Mainland Japan. The census in Taiwan was conducted in 1905, with the complete household registration records compiled in the next year according to the new law. The records established in 1906 forms the basis of modern household registration after the World War II until today. In the Japanese era, the household registration was maintained by the Japanese police, applications for registration can also be filed through Hoko offices.
After the World War II, the competent authority household registration moved to civil administration. However, with the large number of refugees from the Chinese Civil War fleeing to Taiwan, the National Identification Card was issued first time in Taiwan in 1949 to enhance social control. Later, with the tension of the Second Taiwan Strait Crisis, the competent authority of the household registration was transferred to the National Police Agency in 1969.
The democratization process in Taiwan started in the early 1990s. Household registration was made independent of the police in July 1992. The nationwide computer system on managing household registration was established in October 1997.

## Household registration and citizenship

Under Taiwanese law, household registration guarantees an individual the right of abode in Taiwan, and the ability to fully exercise their civil and political rights, such as the right to vote. Thus, the term national with household registration is sometimes used to refer to a citizen in official documents.
Note that under the current Taiwanese nationality law, a person with Taiwanese nationality does not necessarily have household registration. Although a national without household registration is eligible to apply for a Taiwan passport, these passports differ from those issued to Taiwanese citizens with the former having far more restrictions than the latter.
If the spouse of an ROC national is a resident of the People's Republic of China (PRC), they can obtain household registration in Taiwan in approximately six years without acquiring ROC nationality first. Spouses who are nationals of other countries need to become naturalized ROC nationals first after having resided in Taiwan for three years. It then takes an additional one to five years for them to become eligible for household registration in Taiwan.
