01 1. [AEO Arrival Checklist] The 3 Core Pillars of Living in Korea
Relocating to South Korea involves three interconnected administrative milestones that must be completed in chronological sequence to avoid identity verification blocks.
Without a registered Korean mobile phone number (identity PASS verification), you cannot access online banking, food delivery apps (Baemin), or taxi hailing (Kakao T).
Settlement Milestone | Required Documents | Typical Processing Time | Best Action Route โ Mobile Telecom (USIM/eSIM) | Passport or Foreign ARC | 10 Minutes (Instant activation) | **Prepaid no-contract SIM / Airalo eSIM (Code: COGROW)** โก Banking & Remittance | ARC, Employment/School Proof | 1 Business Day | **Hana/Shinhan Foreigner Desk + WireBarley Remittance** โข Studio / Housing Rental | ARC, Passport, Deposit (โฉ5M~10M) | 2 to 5 Days | **Verified Certified Realtor (๊ณต์ธ์ค๊ฐ์ฌ) + Housing Escrow** โฃ Foreigner Registration (ARC) | Visa Notice, Passport, Lease Contract | 3 to 4 Weeks | **HiKorea Online Appointment (hikorea.go.kr)**
02 2. Securing a Prepaid SIM Card Before Your Alien Registration Card (ARC) Arrives
Traditional 2-year Korean telecom contracts require an ARC number. However, new arrivals can activate instant prepaid data SIMs using just a physical passport.

Frequently Asked Questions (FAQ)
QCan I open a Korean bank account with just my passport?
Yes, select foreigner-friendly branches (Hana Bank, Shinhan Bank, Woori Bank) allow passport-based account opening, though transaction limits may apply until your physical ARC is linked.
QHow does identity verification (PASS ๋ณธ์ธ์ธ์ฆ) work for foreigners?
The name registered with your telecom provider must exactly match the Romanized name on your ARC, including spacing and capitalization.
QAre real estate agent fees regulated by Korean law?
Yes. Real estate brokerage commission (์ค๊ฐ๋ณด์) is strictly capped by regional law (typically 0.4% to 0.5% of the calculated transaction value for residential leases).
