Entry & documents
| Term | Meaning |
| K-ETA | Korea Electronic Travel Authorization — online pre-boarding authorization for many visa-free short visits. Official site only: www.k-eta.go.kr (fee ~KRW 10,000). Check your passport; temporary exemptions exist. |
| Temporary K-ETA exemption | Designated nationals may enter without K-ETA until 31 Dec 2026 (KST) per current official notices. Lists change — confirm on K-ETA / Visit Korea. Exemption ≠ “no forms”: e-Arrival often still required. |
| e-Arrival card | Free electronic arrival declaration at www.e-arrivalcard.go.kr only. Generally required if you do not hold a valid K-ETA (including many temporary-exemption travelers). Submit from 3 days before arrival (KST); validity 72 hours after submit. Separate from K-ETA. |
| Visa-free stay | Allowed stay length varies by nationality; confirm on visa.go.kr / immigration sites. |
| HiKorea / 1345 | Immigration info: Hi Korea (EN); dial 1345 inside Korea (or +82-1345 from abroad). |
Transit
| Term | Meaning |
| ICN | Incheon International Airport — airport.kr. |
| GMP | Gimpo Airport (more domestic / some regional). |
| AREX | Airport Railroad Express (ICN ↔ Seoul Station area) — arex.or.kr. |
| T-money | Reloadable transit card for Seoul subway/buses (and some other uses) — t-money.co.kr. |
| Korail / KTX | National rail & high-speed trains (separate from city T-money) — book via korail.com EN tickets (letskorail.com redirects to Korail). |
| Transfer window | Time limit for discounted transfers between bus/subway — check current rules in transit apps. |
| Seoul Metro | City subway operator visitor info — seoulmetro.co.kr/en. |

Install tips
- 1Install Naver Map (or KakaoMap), Papago, and KakaoTalk before you fly; log in on Wi-Fi.
- 2Download offline Korean language packs and save hotel pins while you still have home data.
- 3Prefer the official websites above (or App Store / Google Play search for the exact brand name). Avoid look-alike “agency” sites for K-ETA or arrival cards — Korea Immigration has warned about fake e-Arrival websites that ask for payment; use only the official links above.
- 4Convenience stores (CU, GS25, 7-Eleven) are where many visitors buy or top up T-money and pick up SIMs.
TipNot legal advice. Store listings and app features change; official sites win when wording differs.
