Travel to Thailand checklist: 10 steps before you fly
Use this checklist before every trip to Thailand. Entry is fully open in 2026, but immigration still expects the right visa or exemption, a completed TDAC, and documents officers may ask for at the counter. Skipping a step here is the fastest way to lose time at Suvarnabhumi, Don Mueang, or a land border checkpoint.
Our Bangkok team built this list from questions we hear daily at Thai Visa Centre. Work through all ten steps in order, then keep your confirmation documents accessible offline. For deeper entry scenarios, see our Thailand entry requirements guide and the extended 2025 to 2026 walkthrough.
Submit before arrival using Thailand time. Required for air, land, and sea entry since 1 May 2025.
COVID registration ended in 2022. Ignore outdated blog posts that still mention it.
Recommended for all travellers. VOA requires at least 30 days beyond arrival date.
Eligible passports only. Confirm your nationality on the official exemption list before booking.
Ten-step pre-travel checklist
Work through these ten steps before your departure date. Each step below expands the headline checklist item with practical detail from our Bangkok consultations. Tick them off in order because visa category and TDAC must be correct before you focus on packing or local tips.
Step 1: Confirm your visa or exemption status
Start every trip by checking whether your passport qualifies for visa exemption on the official list published by Thai immigration. If you are not exempt, decide between a pre-approved tourist e-Visa, visa on arrival at an eligible checkpoint, or a long-stay category such as DTV before you buy non-refundable flights. Staying months rather than weeks usually means you need a proper visa category, not repeated tourist entries. When in doubt, match your passport to a category on our exemption and VOA guide or browse all visa types before departure.
Step 2: Complete TDAC (mandatory)
Since 1 May 2025, every foreign visitor must submit the Thailand Digital Arrival Card online within 72 hours of arrival using Thailand time. TDAC applies to air, land, and sea entry, is free at tdac.immigration.go.th, and is required on every entry including for long-stay visa holders returning from a short trip abroad. Save the confirmation email and a screenshot offline because airport Wi-Fi can fail at the counter. TDAC replaced the paper TM6 card, not Thailand Pass, and it does not replace a visa approval.
Step 3: Prepare passport and supporting documents
Carry a passport with at least six months validity recommended, a return or onward ticket within your permitted stay, and proof of accommodation that matches what you entered on TDAC. Immigration may also ask for proof of funds, especially for visa on arrival where officers commonly expect 10,000 THB solo or 20,000 THB for a family in cash or accessible balance. If you applied for an e-Visa, keep a printed or digital approval accessible in hand luggage along with your TDAC confirmation screenshot. Officers can request any of these before you collect checked bags.
Step 4: Arrange travel insurance
Travel insurance is not universally mandatory for short tourist entry in 2026, but it is strongly recommended because Thai hospitals expect payment for uninsured care and outpatient costs add up quickly. Retirement, LTR, and some other long-stay visa categories require approved insurance meeting category minimums, so confirm your policy before you apply or renew. If you plan scooter riding, diving, or adventure activities, verify those are covered rather than assuming a basic policy includes them. Read our health insurance guide for category-specific guidance.
Step 5: Review health requirements
As of June 2026, Thailand does not require COVID vaccination proof, pre-arrival PCR or ATK tests, or quarantine for standard tourist entry. That is a major change from pandemic-era travel, but it does not mean health planning is optional. Check MFA and airline notices before you fly in case outbreak-specific advisories appear, and carry any personal medications in original packaging with a copy of prescriptions if applicable. Mosquito-borne illnesses remain a seasonal concern in some regions, so pack repellent if you are visiting rural or island areas.
Step 6: Plan money and connectivity
Notify your bank of travel dates and carry a backup card because card declines at arrival are common when fraud systems flag foreign transactions. Airport ATMs and exchange counters exist at major gateways, but some visa on arrival fees require Thai baht cash at the counter. Thailand uses 220V power, so pack an adapter if your plugs differ. Buy an eSIM before you fly or pick up a tourist SIM at the airport so maps, ride apps, and TDAC proof stay accessible even when airport Wi-Fi is slow.
Step 7: Book accommodation
Immigration officers may ask where you are staying on arrival, and your answer should match the address on TDAC and any hotel confirmation you carry. Licensed hotels simplify TM30 address registration later if you apply for extensions or switch to a long-stay visa while in Thailand. If you are staying with friends or in a private apartment, confirm the host can support TM30 reporting before you rely on that address for immigration paperwork. A refundable booking for your first nights reduces stress if your flight arrives late or your original plan changes.
Step 8: Pack for Thailand's climate
Thailand is hot year-round with regional rainy seasons, so light breathable clothing should form the core of your luggage. Add a compact rain layer during monsoon months, reef-safe sunscreen for islands and snorkeling, and modest temple wear that covers shoulders and knees for visits to wats and royal sites. Leave heavy formal clothing at home unless you have a specific event, and prefer quick-dry fabrics over denim for comfort in humidity. Sandals work for beaches and cities, but pack closed shoes if you plan hiking or motorbike riding.
Step 9: Know local basics
Save emergency numbers before you land: 191 for police, 1669 for ambulance, and tourist police at 1155 for English-speaking help. Respect temple dress codes, local customs, and Thailand's lèse-majesté laws, which apply to speech and social media posts about the monarchy. Tourist visa exemption and tourist stamps do not authorise employment in Thailand, including many remote-work arrangements performed while physically in the country. Learning a few Thai greetings goes a long way, but compliance with immigration and local law matters more than language fluency for a smooth trip.
Step 10: Save Thai Visa Centre contact details
If visa or immigration questions arise before or during your trip, keep TVC contact details accessible offline. Our Bangkok team handles visas, TDAC review, and entry paperwork every day and can help when airline check-in staff or forum advice conflict with official rules. Book an appointment, start live chat, or message us if your situation involves extensions, overstay risk, or a passport that does not fit standard exemption paths. Saving contact details costs nothing and can save a trip when plans change at the last minute.
Visa and exemption: choose before you book flights
Your passport nationality determines which entry paths are open to you. Most short-term visitors use exemption, visa on arrival, or a tourist e-Visa, while longer stays need a dedicated category applied before travel. Confirm eligibility on the official exemption list rather than relying on social media summaries that may reference retired rules.
Visa exemption
Up to 60 days per entry for eligible passports. Confirm nationality on the official exemption list. Carry return ticket and funds proof even when no visa was required to board.
Read guideVisa on Arrival
15 days at designated checkpoints for limited nationalities. Fee is 2,000 THB at eligible air, land, and sea points. Confirm your checkpoint accepts VOA before you travel overland.
Read guideTourist e-Visa
Typically 60 days, extendable in Thailand. Best when your passport is not exempt and you want pre-approval before flying. Allow embassy processing time in peak season.

TDAC: mandatory for every foreign visitor
Since 1 May 2025, all non-Thai nationals must complete TDAC online before entry by air, land, or sea. Submit within 72 hours of arrival using Thailand time at tdac.immigration.go.th. The form is free, required on every entry, and replaces the old paper TM6 arrival card. Thailand Pass is abolished, so ignore outdated blog posts that still mention COVID registration.
Avoid copycat sites charging fees. We offer field-by-field help on our TDAC guide and a pre-flight review at our TDAC service page.
Remember: TDAC is registration only. Immigration still decides admission based on visa category, funds, tickets, and discretion at the counter. A completed TDAC does not guarantee entry or replace visa approval.
Passport and documents to carry
Immigration officers may request any of the following at the counter. Keep copies accessible on your phone and in hand luggage, not only in checked bags. Requirements vary by entry path, but carrying the full set avoids delays when an officer asks for extra proof beyond what your airline checked at departure.
- Passport valid 6+ months recommended. VOA requires at least 30 days beyond arrival date.
- Return or onward ticket dated within your permitted stay length.
- Hotel booking or host address matching TDAC and immigration answers.
- Proof of funds if requested. VOA commonly expects 10,000 THB solo or 20,000 THB family equivalent.
- Printed or digital e-Visa approval when entering on a pre-approved visa.
- TDAC confirmation screenshot and email saved offline on your phone.
- Travel insurance certificate when your visa category requires it or you want hospital coverage.

Travel insurance
Travel insurance is not universally mandatory for short tourists in 2026, but it is strongly recommended because Thai hospitals expect payment for uninsured care and repatriation costs are expensive. Retirement, LTR, Elite, and some other long-stay routes require approved insurance meeting category minimums before approval or extension. If you ride scooters, dive, or join adventure tours, confirm those activities are covered rather than excluded in fine print.
Read our health insurance in Thailand guide for policy types, typical costs, and visa-category requirements before you travel.
Health requirements (June 2026)
Standard tourist entry no longer requires COVID vaccination proof, pre-arrival PCR or ATK tests, or quarantine. That reflects the post-pandemic return to normal immigration policy, not an absence of all health planning. Check MFA and airline notices before you fly in case outbreak-specific advisories appear, and carry personal medications in original packaging with prescription copies when applicable.
Historical COVID-era guides remain online but do not reflect current rules. For context on what changed, see our 2022 travel archive and 2026 entry requirements.
Money and connectivity
Notify your bank of travel dates and carry a backup card because foreign transactions trigger fraud holds on many accounts. Airport ATMs and exchange counters exist at BKK, DMK, Phuket, and Chiang Mai, but some visa on arrival fees require Thai baht cash at the immigration counter. Thailand uses 220V power with several plug types, so pack an adapter if your chargers are not universal. Buy an eSIM before departure or pick up a tourist SIM on arrival so maps, ride apps, and TDAC proof stay accessible when airport Wi-Fi is slow or unavailable.
Accommodation and TM30
Immigration may ask where you are staying on arrival, and your answer should match TDAC and any confirmation you carry. Licensed hotels usually file TM30 address registration for guests, which simplifies later extensions or visa changes while you are in Thailand. If you stay with friends or in a private condo, confirm the landlord or juristic person can file TM30 before relying on that address for immigration paperwork. Book at least your first nights before arrival to reduce stress if your flight is delayed or plans change at the last minute.
Packing for Thailand's climate
Thailand is hot year-round with regional rainy seasons, so pack light and prioritize breathable fabrics over heavy layers. Temple visits require modest clothing covering shoulders and knees, while islands and boat days call for reef-safe sunscreen and a compact rain layer during monsoon months. These essentials cover most tourist itineraries without overloading your luggage.
- Light breathable clothing for heat and humidity year-round.
- Modest temple outfit covering shoulders and knees.
- Compact rain jacket or umbrella during monsoon season.
- Reef-safe sunscreen for beaches and boat trips.
- Insect repellent for evenings and rural areas.
- 220V power adapter compatible with Type A, B, C, F, and O outlets used in Thailand.
- Prescription medications in original containers with copies of scripts.
Local basics every visitor should know
Save emergency numbers and basic rules before you land so you are not searching under stress. Respect temple dress codes, local customs, and Thai law including lèse-majesté rules that apply to speech and online posts. Tourist entry categories do not authorise employment in Thailand, including remote work performed while physically in the country.
Common checklist mistakes
These errors show up repeatedly in our Bangkok office consultations. Most are avoidable with a fresh checklist and official sources, not forum posts from 2021 or 2022 that still mention Thailand Pass or quarantine hotels.
- Using outdated COVID checklists that still mention Thailand Pass, vaccination proof, or quarantine hotels. Those requirements ended years ago. TDAC is the current mandatory pre-arrival step for every foreign entry.
- Assuming TDAC replaces a visa. TDAC is arrival registration only. Immigration still decides admission based on visa category, funds, tickets, and discretion at the counter.
- Submitting TDAC on copycat sites that charge fees. The official form is free at tdac.immigration.go.th. Third-party sites may collect data without delivering a valid confirmation.
- Arriving with only a one-way ticket when immigration expects proof you will leave within your stamp period. Risky for exemption, VOA, and tourist visa entries alike.
- Entering repeatedly on visa exemption when your real plan is long-term stay or remote work. Officers compare entry history and may deny or shorten stamps. Choose DTV or another proper category instead.
- Storing all documents in checked luggage or cloud-only storage with no offline access. Immigration questions happen at the counter, often before you collect bags or when airport Wi-Fi is unreliable.

Frequently asked questions
Quick answers to the questions we hear most often at Thai Visa Centre. Rules change, so verify against official sources before you travel if your trip is weeks away.
Q:Is Thailand Pass still required?
A:No. Thailand Pass ended in 2022 and is not used at any checkpoint today. TDAC replaced the paper TM6 arrival card, not Thailand Pass. If an old blog or forum post still mentions Thailand Pass, ignore it and complete TDAC instead.
Q:Can I enter with only a one-way ticket?
A:That is risky for most entry paths. Immigration often wants proof you will leave Thailand within your permitted stay, and airlines may deny boarding before you reach the counter. Book a return or onward ticket within your stamp period, or carry verifiable proof of onward travel if your itinerary is flexible.
Q:Do long-stay visa holders need TDAC?
A:Yes. Every foreign entry requires TDAC regardless of visa type, including retirement, marriage, LTR, and Elite members returning from a short trip abroad. Submit within 72 hours of each arrival using Thailand time on the official immigration domain only.
Q:Do children need their own TDAC?
A:Yes. Each foreign passport holder needs a separate TDAC submission, including infants and toddlers. Parents complete one form per child. One family cannot share a single TDAC under one adult passport.
Q:Is travel insurance mandatory for tourists?
A:Not universally mandatory for short tourism entry in 2026, but strongly recommended because Thai hospitals expect payment for uninsured care. Retirement, LTR, and some other visa categories require approved insurance meeting category minimums. Carry a policy that covers inpatient treatment even on tourist paths.
Q:When should I submit TDAC?
A:Within 72 hours of your arrival time using Thailand time, not your home timezone alone. Submitting too early can cause timing issues on some forms, and submitting late can delay you at immigration. Save the confirmation offline before you board your flight or cross the border.
Q:What proof of funds do officers expect?
A:Requirements vary by entry path. Visa on arrival commonly expects 10,000 THB per solo traveller or 20,000 THB per family in cash or accessible balance. Exemption and tourist e-Visa travellers should still carry evidence even when not strictly published, because officers have discretion at the counter.
