Published: September 2026 | Last reviewed: September 2026. This article is for informational purposes only. We are not affiliated with the Republic of Korea government or the K-ETA system. The only legitimate K-ETA portal is k-eta.go.kr.
If your K-ETA is denied, you cannot formally appeal the decision. Your options are to reapply with corrected information (10,000 KRW per attempt, up to 3 times in 6 months), apply for a C-3 tourist visa at the Korean Embassy in London, or check whether you qualify for a 2026 exemption. A denied K-ETA does not permanently ban you from South Korea.
UK passport holders may have a temporary K-ETA exemption through 2026. Before reapplying, verify your status on the K-ETA portal at k-eta.go.kr, where the latest exemption notices are published.
Why Was My K-ETA Denied? Common Rejection Reasons
K-ETA uses AI screening and does not disclose specific denial reasons. Six common causes are listed below.
- Passport data discrepancies – name spelling errors, swapping letter “O” for numeral “0” in the passport number, or a mismatched expiry date are the most frequent causes.
- Non-compliant photo – a colourful background, shadows on the face, glare from glasses, or a file exceeding 100 KB will fail the automated check.
- Criminal record – including minor offences, which must be disclosed regardless of UK Rehabilitation of Offenders Act 1974 status.
- Prior overstay – having previously overstayed a visa in South Korea.
- Invalid accommodation address – using a fake address or entering the field in a language other than English or Korean.
- Incorrect birthdate format or nationality typo – simple data-entry errors that still trigger automatic rejection.
K-ETA Photo and Data Requirements to Prevent Rejection
Photo and data errors are caught automatically before human review.
To avoid having your K-ETA denied on technical grounds, follow these photo specifications:
- Background: plain white only – no colours or patterns.
- Lighting: natural daylight, no flash, no shadows behind ears or on face.
- Glasses: not permitted if they produce glare.
- File size: maximum 100 KB.
- Format: JPG or PNG.
Equally important are the data-entry rules that prevent a K-ETA denial caused by discrepancies:
- Your passport expiration date must match the passport exactly.
- The address field accepts English or Korean only.
- If you are visiting multiple hotels, enter the address of the first hotel you will stay at.
Using the mobile app’s built-in selfie feature and OCR passport scan reduces the risk of typos that lead to a K-ETA denial.
Does a K-ETA Denial Affect Your Future Korean Visa?
There is no formal administrative appeal for a K-ETA denial. The system does not provide a legal appeal mechanism under the Immigration Control Act (Article 37-1), which governs electronic travel authorisation and port-of-entry decisions. Your only recourse is reapplication with corrected information or applying for a C-3 tourist visa through consular channels.
Repeated rejections – up to 3 applications within a 6-month period – generate a temporary flag on your electronic record. The exact duration of this flag is not publicly disclosed, but based on community reports and the 6-month reapplication window, it likely persists for approximately 6 months. This flag may prejudice a subsequent C-3 visa application, as embassy officers have access to immigration records.
False information risks entry restrictions or penalties under Korean law. This applies equally to all accompanying applicants, including the primary user. A K-ETA approval may be refused or cancelled if inaccurate information is detected at any stage.
How to Reapply for K-ETA After a Rejection
A K-ETA denial forces you to submit a corrected application through the K-ETA portal at k-eta.go.kr, paying a non-refundable fee of 10,000 KRW (approximately USD $7-8) per attempt plus a separate online payment processing fee.
Compare against your passport
Check character by character for common errors such as swapping “O” for “0” in your passport number.
Re-upload a compliant photo
Meet all facial photo requirements and re-submit the form with corrected data.
Pay the 10,000 KRW fee
Submit. Processing takes up to 72 hours, with no expedited service. Applications are reviewed in order received.
Check your status
Use your application number on the portal to track your result.
You may reapply up to 3 times within a 6-month period. A denied K-ETA is not a permanent ban from South Korea.
When to Apply for a Korean Tourist Visa (C-3) Instead
If your K-ETA is denied after 2 rejections for the same information, or if the denial relates to a criminal record or prior immigration violation, consider applying for a C-3 tourist visa at the Korean Embassy in London instead. A C-3 visa costs significantly more than the 10,000 KRW K-ETA fee and processing takes weeks, not days.
| Feature | K-ETA | C-3 Tourist Visa |
|---|---|---|
| Cost | 10,000 KRW (~$7-8) | Significantly more (check embassy) |
| Processing time | Up to 72 hours | Weeks |
| Method | Online (k-eta.go.kr) | In-person at Korean Embassy |
| Documents | Passport, photo, travel info | Passport, bank statements, employment letter, itinerary, cover letter, photo |
| Recommended when | Clean record, minor typos | After 2+ K-ETA rejections or criminal record |
For visa queries, contact the Embassy of the Republic of Korea in London (check their website for current details, fees, and appointment procedures). Prepare a cover letter explaining why you are applying via the embassy route, and bring certified bank statements and employment verification.
What Happens at Korean Border Control and Airlines?
A K-ETA denial complicates your arrival process at Incheon and other Korean ports of entry, triggering secondary inspection procedures even if you later obtain a valid authorisation. Airlines verify K-ETA status via the TIMATIC system at the departure gate and can deny boarding even when you hold a printed confirmation. Airlines risk fines for carrying inadmissible passengers, so they deny boarding strictly.
At border control, a Korea Immigration Service officer holds final authority to deny entry regardless of K-ETA approval. A K-ETA is not a visa and does not guarantee entry into the Republic of Korea. Travellers with a prior K-ETA denial on their record may be directed to a separate queue for secondary inspection, which involves officer interviews, document scrutiny, and possible biometric verification.
If entry is refused at the port of entry, the airline bears the cost of the immediate return flight under the carrier return obligation, and the passenger may be detained until the next available departure. Carry your K-ETA approval printout, accommodation confirmation, return ticket, and proof of funds to streamline the process.
Getting Help: Fraud Sites and Contacting the K-ETA Center
The only legitimate K-ETA portal is k-eta.go.kr. Third-party sites charging inflated fees well above the 10,000 KRW base rate are fraudulent. Red flags include requests for card details outside the standard payment system, poor English, and “guaranteed approval” claims. If you applied on a fake site, contact your bank for a chargeback, change any shared passwords, and report the incident to Action Fraud (UK).
For legitimate inquiries about a K-ETA denial, use the “Ask Us” web form on k-eta.go.kr, providing your email address and K-ETA application number. The K-ETA Center phone number is 02-2666-0463, but the Center does not provide telephone or face-to-face consultations.
Frequently Asked Questions About a K-ETA Denied
Can I get a refund if my K-ETA is denied?
No. The 10,000 KRW application fee is non-refundable, even if your K-ETA is denied. The separate online payment processing fee is also non-refundable.
How long does a K-ETA reapplication take after denial?
Standard processing time is up to 72 hours, with no expedited service available. For minor typo corrections, auto-clearance can process a reapplication in as little as 1 hour. Apply well before your departure date.
How many times can I reapply for K-ETA after rejection?
You can reapply up to 3 times within a 6-month period. Each attempt costs 10,000 KRW and is non-refundable. If rejected twice for the same information, consider applying for a C-3 tourist visa at the Korean Embassy instead.
Do UK passport holders need a K-ETA in 2026?
UK passport holders may be temporarily exempt from K-ETA requirements through 2026, along with citizens of the USA, Spain, Portugal, and other designated countries. Always verify your current status on the K-ETA portal at k-eta.go.kr before applying.
What are ‘spent convictions’ under UK law, and do I need to declare them on my K-ETA?
Korean law does not recognise UK spent convictions under the Rehabilitation of Offenders Act 1974. Declare everything when in doubt to avoid penalties or entry restrictions under Korean law.
Can I transit through Incheon Airport without a K-ETA if my application was denied?
Transit without visa (TWOV) eligibility depends on your nationality, layover length, and whether you remain in the airport transit area. If your K-ETA is denied, consult the Korean Immigration Service or the Embassy of the Republic of Korea in London for guidance before travelling.
What happens if I’m refused entry at Incheon Airport?
The airline bears the cost of your return flight under the carrier return obligation. You may be detained until the next available departure. A port-of-entry refusal can also result in a future entry ban. A valid K-ETA does not guarantee entry into South Korea.
Is the K-ETA still valid for 3 years if I’m approved on my second attempt?
Yes. An approved K-ETA is valid for 3 years from the date of approval, or until your passport expires, whichever is shorter. If your passport is reissued, you must reapply even if the previous K-ETA has not expired.
