Can I use my passport as ID instead of the ARC?

Do I need a Korean phone number to register?

It is highly recommended. Many government systems and the Hikorea appointment site are easier to manage once you have a local number, though you can register without one initially.

How to Register Your Residence (Foreigner Registration) in South Korea

To live in South Korea for more than 90 days, you must register for an Alien Registration Card (ARC) at your local Immigration Office within 90 days of arrival. This card is your primary identification for everything from opening a bank account to signing up for a mobile phone plan.

Check your eligibility. Confirm your visa status allows for long-term residency. Most long-term visas (E-2, D-2, F-series) require registration if staying beyond 90 days.
Book an appointment online. Visit the Hikorea website (hikorea.go.kr) to schedule an appointment at the Immigration Office serving your specific district. Walk-ins are generally not accepted.
Prepare your documentation. Gather your passport, two 3.5cm x 4.5cm color photos, a completed Application Form (Form No. 34), and your Certificate of Residence provided by your landlord or housing office.
Pay the processing fee. The fee is 30,000 KRW. You must pay this in cash at the Immigration Office, usually at an ATM-like kiosk on-site.
Visit the Immigration Office. Arrive 15 minutes before your appointment time. Submit your documents and have your fingerprints scanned. You will be told when your ARC will be ready for collection or mail delivery.
