Last verified: September 20, 2026 · registration duty, Residence Card terminology and passport-change reporting guidance rechecked
Foreign nationals who will stay in Korea for more than 90 days generally need foreign-resident registration unless an official exception applies. After the Residence Card is issued, check the immigration record before aligning phone, bank, school or employer accounts.
For the appointment, documents, fingerprints and application visit, use How to Get Your ARC (Alien Registration Card) in Korea. This guide starts with the duty to register and then owns the post-issuance identity chain.
1. Confirm the Registration Duty for Your Status
The Immigration Act generally requires a foreign national who will stay in Korea for more than 90 days to register within 90 days of entry, subject to statutory exceptions. A person who receives or changes to a qualifying long-term status inside Korea can follow a different registration timing under the applicable rule.
Short-term visitors do not obtain a Residence Card simply to make Korean apps easier to use. A long-term visa, meanwhile, does not mean the registration step has completed itself.
Korea now uses Residence Card as the official English name. Banks, carriers and older guides may still say ARC or Alien Registration Card.
2. Check the Source Record When the Card Arrives
Compare the Romanized name, birth information and other identity/status details against the passport and immigration approval. If something appears wrong, ask 1345 or the responsible immigration office before building more private accounts around the mismatch.

Keep these records in protected storage. They are useful after a loss or correction, but unredacted identity documents do not belong in shared chat rooms or open cloud folders.
3. Ask the Mobile Carrier What Identity It Has on File
A line opened with a passport may still have passport-based subscriber information after a Residence Card is issued. Do not assume the carrier updates it automatically or that every plan requires the same change.
Ask which document currently anchors the subscriber record and how the legal name is stored. If mobile identity verification fails, use Korean Phone Verification Not Working? Fix Name, ARC & Carrier Mismatches.
4. Align Banking and Institutional Records as Needed
Bring the original Residence Card when a bank asks to update the customer profile. Ask whether the bank needs separate changes for online banking, transfer limits, tax-residency information or another product record. The card proves an official identity/status record; individual product eligibility remains the institution's decision.
Schools, employers and insurers also maintain their own records. Use their approved channels and provide only the identity information they actually need.
5. Treat Passport Details as Reportable Registration Information
The Immigration Act's general registered-information rule uses a 15-day reporting period for listed changes, including passport number, passport issue date and passport expiry date.
Korea Immigration's current passport-change guidance also applies an operational timing rule based on the passport's issue and actual receipt dates: it describes reporting within 45 days of the new passport's issue date, and a 15-day period from actual receipt when later receipt can be proven through official documentation.
The statute and the passport-specific administrative guidance describe the timing from different angles. Do not reduce them to “15 days after a new passport” without checking the issue/receipt facts.
Where an immigration update is required, complete the source-record step before trying to make banks, carriers and other institutions agree with a passport number that immigration has not yet updated.
6. Other Changes Can Trigger Their Own Reporting Route
A move, name or nationality change, affiliation change or status-specific change can require a different report and deadline. Address changes, for example, are not the same transaction as updating a passport.
Use the current HiKorea procedure or 1345 for the change that actually occurred rather than saving everything for the next extension application.
7. Keep Status and Permitted Activities Separate From the Plastic Card
The Residence Card does not itself answer whether a particular job, side activity, course or re-entry plan is permitted. The underlying status and current immigration record control those questions.
If an extension or status change is pending when overseas travel is planned, confirm the effect on that exact case before departure.
