If your passport is missing
Check your belongings and last locations from a safe place. Keep any passport photo or copy available for identification, but do not assume a copy is sufficient for international travel.
Contact your own embassy or consulate
Ask your country's mission in Korea how to replace your passport or obtain an emergency travel document, what proof and photographs are required, and whether an appointment is needed. For example, the British Embassy Seoul directs eligible British nationals who have lost a passport and cannot replace it in time to apply for an emergency travel document. Other countries have different rules.
Police, airline and immigration
If theft or another crime is involved, contact police on 112. Ask your embassy whether a police report is required for your particular application. If departure is near, contact your airline about acceptance of replacement documents and booking changes. Check immigration or visa conditions with the relevant Korean authorities if necessary.
Language support and emergencies
The Korea Tourism Organization lists the multilingual travel hotline 1330. It cannot replace police, emergency responders or consular decisions. Call 119 for medical or fire emergencies, and 112 for police.
Never post passport images or personal document details in public comments or unverified channels.
