Quick answer: Korea's entry paperwork confuses agents because it is not one system but three, and a client needs a different combination depending on nationality. As of 20 September 2026: K-ETA is the electronic travel authorisation for visa-free nationals, but a temporary exemption covering 67 countries and territories runs to 31 December 2026, so most Western and Gulf clients do not currently apply for it. Those exempt clients instead file the e-Arrival Card, which replaced the paper landing card and is submitted online within 72 hours of arrival. Q-Code is the separate health declaration and is generally recommended rather than required. The trap is the inversion: holding a valid K-ETA removes the e-Arrival Card requirement, so the client with less paperwork at home has more at the airport. Explera DMC Korea briefs every group against its own passport mix rather than against a single rule, and flags the expiry date to any agent quoting 2027 travel.
The three systems, and which client needs which
- K-ETA — the electronic travel authorisation for nationals who may enter Korea without a visa. Applied for online in advance, valid for multiple entries across its validity period, and currently waived for a large list of countries under a temporary exemption.
- e-Arrival Card — the electronic replacement for the paper landing card. Required for foreign visitors arriving without a valid K-ETA, which under the present exemption means most of them. Filed online within a 72-hour window before arrival; the traveller carries the resulting QR code.
- Q-Code — the health and quarantine declaration. Generally recommended rather than mandatory for a routine arrival, and its main value is avoiding the manual queue at the airport.
- A visa — for nationals outside the visa-free arrangements entirely, which is a different conversation and a longer lead time.
- The counterintuitive part. K-ETA and the e-Arrival Card are alternatives, not a sequence. A client who holds a valid K-ETA does not file the e-Arrival Card; a client covered by the exemption does. Briefing a mixed-nationality group with one instruction gets half of them wrong.
The date that belongs in your 2027 planning
The K-ETA exemption is temporary and currently runs to 31 December 2026. It has been extended more than once, and it may be extended again — but it has not been, as of this writing, beyond that date.
For an agent that matters now rather than in December, because Q1 2027 departures are being quoted today. A client arriving on 2 January 2027 falls under whatever regime applies then, and if the exemption lapses that client needs a K-ETA obtained in advance. The safe position on a 2027 quote is to say the requirement is under review and will be confirmed closer to travel, rather than to promise the current position will hold.
We watch this date and tell partner agents when it moves. It is exactly the kind of change that is announced with limited notice and reaches the trade late.
What this means for a group booking
Collect the passport mix early
A group is rarely one nationality, and the paperwork splits by passport rather than by booking. Get the nationality list at deposit stage, not at final documentation, so the split is known while there is time to act on it.
Brief in two halves
Send exempt travellers the e-Arrival Card instruction with its 72-hour window, and non-exempt travellers the K-ETA instruction with a much longer lead time. One combined email produces a group where nobody is sure which applies to them.
The 72-hour window is a real operational constraint
It is short enough that a client who files too early is refused and one who leaves it to the airport is stuck. For a group, this means a reminder scheduled three to four days before departure rather than a single instruction sent with the final documents.
Keep the QR codes retrievable
Clients lose them. A tour leader holding a copy of every confirmation, and a DMC with the same file, turns a potential hold-up at the counter into a non-event.
At the airport
- Automated gates are available to many arriving travellers and are considerably faster than the staffed desks, but eligibility varies and a group should not assume it.
- Incheon has two terminals. Confirm which one the group lands at before dispatching a meet; the inter-terminal shuttle is a real time cost when the guide is at the wrong building.
- Clearance times swing with the arrival bank. One widebody clears quickly; four arriving together do not. Build a realistic meet window rather than the best case.
- Onward domestic connections need a buffer that accounts for immigration, baggage and the terminal change, not just the published minimum.
- Nobody at the airport can fix missing paperwork quickly. This is a pre-departure problem in every case, which is why the briefing matters more than the meet.
Confirm it against the source, every time
Entry rules are the fastest-moving thing in this business and the most damaging to get wrong, so this guide is dated deliberately: it describes the position as at 20 September 2026 and should be reconfirmed against the official portals at the time of booking rather than relied on months later. K-ETA is administered at k-eta.go.kr and the e-Arrival Card at e-arrivalcard.go.kr; both are free and neither needs an agency intermediary, which is worth telling clients who find paid look-alike sites first.
Explera DMC Korea briefs entry requirements per group against the actual passport mix, schedules the e-Arrival Card reminder inside its 72-hour window, holds copies of the confirmations, and tells partner agents when a rule moves rather than leaving them to find out. Send your group's nationality split to b2b@explera.kr or WhatsApp +66 93 656 8090 and we will tell you which half needs what. Explera DMC Korea is IATA TIDS-registered (96215733) and an ASTA member.
