You do not usually need to print your South Korean eTA, as it is electronically linked to your passport upon approval.
What You Need to Know
The South Korean immigration system verifies your eTA electronically when you present your passport at entry. While a printed copy is not generally required, some airlines or immigration officers may ask to see proof of approval. Having a digital copy on your phone is typically sufficient, but carrying a printed version can help avoid issues if systems are unavailable.
Our Recommendation
Keep your eTA approval easily accessible on your mobile device and carry a printed copy as a precaution for your journey.
A Quick Tip
Save a backup copy of your eTA approval in your email or cloud storage so you can access it quickly if needed.
