What are the disadvantages of not registering residence?

What the Law Says

South Korean law requires all residents — including Korean nationals and foreign nationals staying longer than 90 days — to register their residence within 30 days of moving. Failure carries legal consequences under the Resident Registration Act.

Under the Resident Registration Act, every person who establishes a residence in South Korea must report it to the local municipal office within 30 days. This applies to both Korean citizens and eligible foreign nationals (e.g., those with long-term visas or permanent residency).

Without registration, individuals cannot obtain a resident registration number (RRN), which is required for nearly all government and financial services — including national health insurance (NHIS), public education enrollment, bank accounts, mobile phone contracts, and employment reporting.

The law also ties residence registration to civic duties: only registered residents may vote in local elections, and unregistered male citizens aged 18–35 may face complications in military service exemption procedures.
