K-ETA Application: Complete Step-by-Step Guide for British Travellers (2026)

The K-ETA application is a mandatory online pre-travel authorisation for visa-free entry into South Korea, costing KRW 10,000 and processing within 30 minutes to 72 hours. UK passport holders are temporarily exempt from the K-ETA requirement until 31 December 2026. From 1 January 2027, British travellers will need a valid K-ETA before departure.

What Is K-ETA and Who Needs It in 2026?

K-ETA (Korea Electronic Travel Authorization) is South Korea’s electronic travel authorisation required for visa-free entry by citizens of 112 eligible countries (66 visa-waiver and 46 visa-free). It is a pre-screening system, not a visa, that evaluates travellers before they board their flight to the Republic of Korea.

You must complete a K-ETA application if you hold a passport from a visa-waiver country and plan to visit South Korea for tourism or short-term business, with a maximum stay of 90 days. An onward or return ticket is mandatory.

Certain groups are exempt from the K-ETA application requirement. Travellers aged 17 and under and those aged 65 or above do not need to apply, effective from 3 July 2023.

British passport holders benefit from a temporary exemption valid through 31 December 2026, per a notice published on k-eta.go.kr on 20 March 2026 and confirmed by GOV.UK. From 1 January 2027, UK citizens will need a valid K-ETA approval before departure. You can verify eligibility and submit your K-ETA application through the K-ETA portal at www.k-eta.go.kr or via the K-ETA mobile app.

Before You Start: Required Documents & Photo Specs

Before you start your K-ETA application on the K-ETA portal, gather the following items:

• Valid passport: expiry date must fall after the date you leave South Korea for short-term stays; at least 6 months validity is recommended for longer visits.
• Passport data page scan: place the passport flat on a surface with no reflections; all four corners must be visible and the text legible.
• Digital passport-style photo: JPG or PNG format, file size under 500 KB, white or light-coloured plain background, no glasses, no hats, neutral expression. Hijab is permitted provided the face remains fully visible (per K-ETA FAQ Q54, published 2025). Children must appear alone in the photo, not held by a parent.
• Email address: you receive your approval notification here. Gmail delivery delays were reported in a K-ETA notice dated 13 March 2026; triple-check the address for typos.
• Credit or debit card: Visa or Mastercard recommended for reliable payment of the KRW 10,000 fee.
• Travel details: flight number and accommodation address in South Korea.

K-ETA Application Step-by-Step Guide

Step 1: Create Account or Apply as Guest

You can apply as a member (sign up with email and password, letting you view multiple K-ETA application records such as those for family members in a single dashboard) or as a non-member (email verification per session: a faster route if you only need one K-ETA application, but you cannot track history afterwards).

Steps 2-5: Personal, Passport & Travel Details

Enter passport number, full name exactly as on passport (including middle names, per FAQ Q57 on k-eta.go.kr, which notes passport scans can auto-fill the surname field incorrectly), date of birth, nationality, flight number, and accommodation address in South Korea. Double-check passport numbers for O/0 and I/1 confusion, and verify the date format to avoid DD/MM vs MM/DD errors.

Step 6: Upload Documents & Declarations

Upload a passport scan (flat surface, all four corners visible, no glare) and digital photo (JPG or PNG, under 500 KB, white background). Then complete the health and criminal-history declaration. The K-ETA mobile app offers camera-based passport scanning that simplifies data entry.

Step 7: Payment & Submission

Pay the KRW 10,000 fee by credit or debit card and submit your K-ETA application. Save the confirmation reference number: you will need it to check your application status on the portal. Desktop browsers provide more reliable 3D Secure (3DS) payment popups; first-time applicants should use the desktop portal, while the mobile app suits re-applications.

Paying the Fee & Processing Time

The K-ETA application fee is KRW 10,000 (~GBP 5.80 / ~USD 7-8), payable by credit or debit card only (no PayPal, no bank transfer). Visa and Mastercard are the most reliable networks; AMEX and JCB have variable support. The fee is non-refundable, even if your K-ETA application is denied or withdrawn. 3D Secure (3DS) authentication is required; per FAQ Q52 on k-eta.go.kr, 3DS errors can occur, so ensure your bank permits overseas transactions before you submit.

Processing times: straightforward cases receive automatic approval within 30 minutes, while applications flagged for manual review take up to 72 hours (per k-eta.go.kr and GOV.UK). The minimum deadline set by Korea Immigration Service is 24 hours before departure; we recommend applying at least 7 days before departure to avoid denied boarding.

Results fall into three categories: OK (approved; K-ETA linked to passport electronically; exempt from arrival card submission), Not OK (denied), or Selectee (secondary inspection and in-depth interview on arrival; still exempt from arrival card). An approved K-ETA is valid for 2 years from the date of approval and permits multiple entries into South Korea within that period, per immigration.go.kr.

10 Common K-ETA Application Mistakes & Denial Recovery

Avoid these 10 common errors (per k-eta.go.kr notices including the error-fix guide published 21 November 2025) to prevent delays or denials of your K-ETA application:

• 1. ❌ Name does not match passport exactly (middle names, spacing) → ✅ Copy name letter-for-letter from the passport data page
• 2. ❌ Wrong date format (DD/MM vs MM/DD confusion) → ✅ Follow the portal’s format exactly
• 3. ❌ Passport number typo (O vs 0, I vs 1) → ✅ Double-check against the passport data page
• 4. ❌ Poor-quality photo (blurry, wrong background, wearing glasses) → ✅ White background, no glasses, clear face, neutral expression
• 5. ❌ Photo file too large or wrong format (BMP instead of JPG or PNG) → ✅ JPG or PNG, under 500 KB
• 6. ❌ Expired or soon-to-expire passport → ✅ Ensure passport is valid beyond your stay dates
• 7. ❌ Wrong email address (missed approval notification) → ✅ Triple-check; note Gmail delivery delays (notice dated 13 March 2026)
• 8. ❌ Unsupported payment card or 3DS not enabled → ✅ Use Visa or Mastercard; enable 3DS with your bank
• 9. ❌ Applying too late (under 72 hours before departure) → ✅ Apply at least 7 days before departure
• 10. ❌ Using a third-party scam website → ✅ Only use www.k-eta.go.kr or the official K-ETA mobile app

If your K-ETA application returns “Not OK”, there is no formal right of appeal and the KRW 10,000 fee is non-refundable. You may re-apply immediately with corrected details, or apply for a C-3 short-term tourist visa through the South Korean Embassy in the UK. Direct inquiries to the K-ETA Center via the “Ask Us” section on www.k-eta.go.kr; the telephone 02-2666-0463 is listed but does not provide consultations.

Avoiding K-ETA Scams and Third-Party Traps

Only one legitimate portal exists for your K-ETA application: www.k-eta.go.kr or the K-ETA mobile app (App Store and Google Play Store). GOV.UK explicitly warns that third-party K-ETA websites are generally scams.

The legitimate portal charges exactly KRW 10,000 with no processing surcharges. Red flags include fees above KRW 10,000, guarantees of approval, requests for unnecessary personal data, and sponsored search ads.

If you have already paid a fraudulent site for your K-ETA application, contact your bank or card issuer immediately to dispute the charge, then complete a new K-ETA application through the legitimate portal.

K-ETA vs e-Arrival Card vs Q-Code

K-ETA is a paid pre-travel authorisation, the e-Arrival Card is a free digital arrival form, and Q-Code is a health screening requirement. All three may be required simultaneously; they are separate, independent systems.

The United Kingdom is designated as a Quarantine Inspection Required Area. Travellers from the UK must submit a Q-Code or a paper-based health questionnaire on arrival. Failure to complete required health screenings results in a fine of up to KRW 10 million.

Your K-ETA application remains valid for 2 years from the date of approval, allowing multiple entries. The e-Arrival Card covers individual groups of 1 to 9 persons or groups of 2 to 1,000 persons and must be submitted separately for each trip.

Practical Tips: Families, Mobile App & Passport Renewals

Every traveller, including infants, needs an individual K-ETA application. A family of four submits four applications at KRW 10,000 each. Creating a member account on www.k-eta.go.kr lets you manage multiple family submissions sequentially and view all records in one dashboard.

The K-ETA mobile app (iOS and Android) offers camera-based passport scanning that simplifies data entry. Desktop browsers provide more reliable 3D Secure (3DS) payment popups and full-screen data review. First-time applicants should use the desktop portal; the mobile app suits re-applications.

A renewed passport carries a new identity record, so any existing K-ETA application linked to the old passport number becomes invalid. You must re-apply with the new passport details; the same applies after a legal name change or occupation change (per k-eta.go.kr FAQ Q53).

Travellers with dual nationality should present the passport matching their K-ETA application at airline check-in. A passport mismatch risks denied boarding, as airlines verify K-ETA approval against the passport details on file.
