Koh Samui Entry Requirements
Visa, immigration, and customs information

Thailand Digital Arrival Card (TDAC)

- All non-Thai nationals entering Thailand by air, land or sea, including infants and children and visa-exempt or visa-on-arrival travellers

The TDAC is filed online or in THIM, the Thai Immigration Bureau's official app, and is not a visa. Crew, and transit passengers who do not pass through immigration, do not need one. Kiosks and Wi-Fi are available on arrival. Look-alike websites charge for this free card.

An extension of up to 30 days can be requested in Thailand. Travellers planning more than two visits a year, or a purpose other than tourism, should apply for a visa.

Visa Requirements
Entry permissions vary by nationality. Find your category below.
Thailand applies one visa policy nationwide. Koh Samui follows identical rules. Your passport determines everything. Length of stay varies by nationality.
Certain nationalities enter Thailand visa-free.
This covers tourism only. Officers may request onward travel proof and funds verification. You receive a stamp on arrival.
Some travelers must apply online for a visa before traveling to Thailand.
Cost: Costs vary by nationality and visa category. Consult the official website for current rates.
The e-visa differs from the Digital Arrival Card. All foreign visitors must complete that separately online before landing. Secure your e-visa before departure.
Travelers from ineligible countries need embassy visas.
Start embassy applications weeks before departure if this applies to you.
Arrival Process
Samui Airport flows in one direction. Deplane, walk to terminal, claim bags, then clear immigration and customs.
Documents to Have Ready
Tips for Smooth Entry
Customs & Duty-Free
Samui Airport enforces standard Thai customs rules. Duty-free allowances match mainland limits.
Prohibited Items
- Narcotics and illegal drugs - severe penalties including imprisonment
- Obscene materials - books, magazines, or videos
- Counterfeit goods or copyright-infringing items
- Firearms and ammunition (without prior permit)
- Fresh fruits, plants, and soil - to prevent pest introduction
Restricted Items
- Psychotropic medications need doctor prescriptions. Carry personal quantities only.
- Electronic cigarettes and vaping devices are banned. Confiscation follows.
- Wildlife products - items made from endangered species require CITES permits
Health Requirements
Most travelers need no specific health documents for Koh Samui entry. Standard precautions still apply.
Required Vaccinations
- No vaccinations are required for entry into Thailand from most countries.
Recommended Vaccinations
- Routine vaccinations (MMR, diphtheria-tetanus-pertussis, varicella, polio, flu)
- Hepatitis An and Typhoid (due to potential for contaminated food/water)
- Hepatitis B vaccination suits those anticipating medical procedures or casual sexual contacts.
Health Insurance
Travel insurance is strongly recommended. Check the current entry rules on the official government website before you travel. But get it anyway. Serious medical issues in Koh Samui often require evacuation to the mainland. Costs add up fast. Verify your policy includes medical evacuation coverage.
Protect Your Trip with Travel Insurance
Comprehensive coverage for medical emergencies, trip cancellation, lost luggage, and 24/7 emergency assistance. Many countries recommend or require travel insurance.

Special Situations
Additional requirements for specific circumstances.
Every child needs their own passport. Traveling with one parent or none? Carry a notarized consent letter from absent parent(s). Immigration might not ask. They might. Better safe than delayed.
Importing a dog or cat to Thailand requires paperwork. Get an import permit from the Thai Department of Livestock Development. You'll need a valid rabies certificate and an official health certificate from your home country's veterinarian. Start early. Months early.
Overstaying your visa exemption or tourist visa? Apply for a 30-day extension at the Samui Immigration Office in Mae Nam. The process is usually simple. Bring the fee. Want longer? Education visas and retirement visas exist. Each has strict criteria. Apply from outside Thailand or visit an immigration office with complete documentation.
