Thailand visa and TDAC: entry rules for Bangkok in 2026
Bangkok: Grand Palace Skip-the-Line Entry Ticket
Do I need a visa to visit Bangkok, and what is the TDAC?
Most Western nationalities (US, UK, EU, Canada, Australia and many other countries) enter Thailand visa-free, currently for 30 days as of mid-2026 — though this has changed recently, so re-verify the day-count before you travel. Your passport must be valid at least 6 months. Separately, everyone must complete the free Thailand Digital Arrival Card (TDAC) online before each entry, up to 72 hours ahead. Beware copycat sites that charge for the free TDAC.
Thailand’s entry rules are straightforward for most visitors, but two things trip people up: the visa day-count, which changed recently, and the mandatory free TDAC arrival card, which copycat sites try to charge for. This guide explains exactly what you need to enter Bangkok in 2026 — visa exemption, passport validity, the TDAC, and the pitfalls to avoid. Because immigration rules are a genuine moving target, treat this as orientation and confirm the current details on the official Thai government portal before you travel.

| Who needs a visa | Many nationalities enter visa-free; others must apply in advance |
| Visa-free stay | Currently 30 days as of mid-2026 — re-verify before travel |
| TDAC | Free, online, mandatory, up to 72hrs before arrival |
| Passport validity | At least 6 months from date of entry |
| Extension | Around 1,900 THB at a Bangkok immigration office |
Visa exemption: who enters visa-free, and for how long
Citizens of many countries — including the US, UK, all EU states, Canada, Australia, New Zealand and many others — enter Thailand under visa exemption, meaning no visa is required for tourism.
The crucial detail is the length of stay, and this is where recent changes matter. Thailand introduced a generous 60-day visa exemption in mid-2024. As of 2026, reporting indicates the visa-free stay was cut back from 60 to 30 days. So at the time of writing the visa-free stay is 30 days for most nationalities — but this is exactly the kind of rule that shifts, so re-verify the current day-count officially before you book and again before you fly.
The visa-exempt stay is typically extendable once, at a Bangkok immigration office, for around 1,900 THB. If you need longer than the exemption allows, look into the proper visa categories (tourist visa and others) rather than relying on extensions or runs.
Passport and onward-travel requirements
Two practical requirements beyond the visa:
- Passport validity: your passport must be valid for at least 6 months from your date of entry. Airlines may refuse boarding otherwise, so check early and renew if needed — this is the single most common reason travellers get caught out.
- Onward/return travel and funds: you should have proof of onward or return travel, and on paper sufficient funds for your stay. These are inconsistently checked, but airlines sometimes ask for onward tickets at check-in.
The TDAC: mandatory, online and free
Since 1 May 2025, every foreign visitor must complete the Thailand Digital Arrival Card (TDAC) before entering the country. It replaced the old paper arrival card and is required for every entry.
Key facts:
- Online and free, completed on the official Thai government portal.
- Submit it up to 72 hours before arrival — not earlier.
- You provide passport details, flight details and your Bangkok accommodation.
- Every traveller needs their own TDAC, including infants and children, each using their own passport.
- Keep the confirmation (digital or printed) to show on arrival if asked.
It takes only a few minutes per person, but do it for the whole family before you fly so it’s not a scramble at the airport.
Avoiding the copycat-site trap
This is the part to be careful about. The official TDAC is completely free, but search results are crowded with copycat and agency websites that mimic the official form and charge a “service fee” to submit it for you. These are unnecessary and best avoided.
The rule is simple: use only the official Thai government portal, and if a site asks for payment to complete your arrival card, you’re on the wrong one. Check the web address carefully before entering any passport or personal details. The same caution applies to “e-visa” and “visa on arrival” agency sites for nationalities that don’t even need a visa — don’t pay for what’s free or unnecessary.
Extensions, visa runs and longer stays
If you want to stay beyond the visa-exempt period:
- Extension: the visa-exempt stay can usually be extended once at a Bangkok immigration office for around 1,900 THB, buying you extra days.
- Visa runs: leaving to a neighbouring country and re-entering can reset a stay, but land-border visa-exempt entries are limited to twice per year, and immigration scrutinises frequent runs. This is not a reliable long-stay strategy.
- Proper visas: for extended stays, apply for the appropriate tourist or longer-stay visa in advance rather than relying on runs.
For most holidaymakers on a trip of a week or two, none of this applies — the 30-day visa-free entry covers you comfortably. It only matters for longer stays.
Entry route at a glance, by length of stay
The right entry route depends almost entirely on how long you plan to be in Thailand. This is a simplified comparison, not a substitute for checking official requirements against your own nationality and dates.
| Route | Typical length | Best for |
|---|---|---|
| Visa exemption | Currently 30 days (re-verify) | Short holidays, most nationalities |
| Exemption + one extension | Around 30 days + extra weeks | A holiday that runs slightly long |
| Tourist visa (applied for in advance) | Typically longer than the exemption | Trips planned to exceed the visa-free stay |
| Non-immigrant / long-stay categories | Months or longer | Work, study, retirement, long-stay purposes — apply well ahead |
If your trip is a straightforward one- to three-week Bangkok holiday, the visa exemption is almost always the right and simplest route, and you can stop reading here and focus on the TDAC. Longer or non-tourist stays are the only case where it is worth researching visa categories before you fly, ideally through the Thai embassy or consulate in your home country rather than a third-party agency site.
What happens at immigration when you land
Arrival in Bangkok is usually quick if your paperwork is in order. After landing at Suvarnabhumi or Don Mueang, you queue at the immigration hall, where an officer checks your passport, your TDAC record (they can look this up digitally, though keeping the confirmation to hand speeds things along), and asks routine questions such as the purpose and length of your visit. Foreign visitors are typically fingerprinted and photographed as part of standard biometric checks.
The officer stamps your passport with your permitted length of stay — check this stamp before you leave the counter, since it is the date that governs your legal stay, not the visa-exemption day-count in the abstract. Queues can run long at peak arrival times, especially early morning and late evening; having your TDAC confirmation and any onward-travel proof ready to show saves a few minutes. Once through, be wary of unofficial “help” from anyone other than uniformed staff — the common Bangkok scams guide covers the touts who sometimes work arrivals halls offering unnecessary paid assistance or overpriced taxis.
Filling in the TDAC without stress
The form itself is not difficult, but a few habits make it painless. Have your passport open next to you and copy the details exactly as printed, including the spelling of your name and the passport number, because a mismatch between the form and the passport is the most likely cause of a delay at the counter. Know your flight number and the date you land before you start, and keep the address of your first hotel or apartment in Bangkok handy, since the form asks where you will be staying.
Because the form can only be submitted shortly before you travel, treat it as a task for the day before your flight rather than something to do weeks ahead. If you are connecting through another airport, think about when the 72-hour window opens relative to your final landing in Thailand, not your first departure. Take a screenshot of the confirmation as well as saving the email or PDF, so you can still show it if your phone has no signal or the airport wifi is slow.
For families and groups, one person can sit down and complete every form in a single session, as long as each traveller’s own passport details are used. Do not be tempted to combine children onto a parent’s form. It is also worth checking, once you have submitted, that the names on your confirmation match the passports before you close the page.
If something goes wrong with your entry
Most arrivals are uneventful, but it helps to know what to do if they are not. If you realise at the airport that you have not completed the TDAC, do not panic: ask airline or airport staff where to complete it, and use only the official portal rather than the first result a search engine gives you. The same applies to a form you submitted with a typo. Correct it through the official channel rather than paying anyone to fix it.
If an immigration officer asks you something you did not expect, such as how long you plan to stay or where you are going next, answer plainly and consistently with your documents. Having your accommodation details and onward travel to hand makes these conversations short. Never hand over your passport to anyone who is not a uniformed official, and be cautious about anyone in the arrivals hall who offers to “fast-track” the process for a fee. The tourist traps guide and the Bangkok scams guide describe the typical approaches so you can recognise them.
If you are denied boarding at home because of passport validity or missing onward travel, the quickest fixes are usually a new booking of a flexible onward ticket or an urgent passport renewal, so it is better to discover the problem weeks before departure than at the check-in desk.
Planning around the rules
Entry rules shape how you plan the rest of a trip. If your stay is short, the visa-free period is a non-issue and you can spend your energy on choosing what to see. A first visit built around the highlights fits comfortably within the exemption, and the how many days in Bangkok guide helps you decide how long you actually need. For ready-made routes, the Bangkok first-timer itinerary and the one-week Bangkok itinerary show how a trip of different lengths can be paced.
If you plan to combine Bangkok with day trips or onward travel in the region, remember that each time you re-enter Thailand you need a fresh TDAC. A day trip that stays inside Thailand, such as to Ayutthaya or Kanchanaburi, does not count as a new entry, but leaving the country and coming back does. The day trips from Bangkok guide covers the options that keep you within the country.
Budget also matters. Extension fees, a new passport or a flexible onward ticket are all costs that are easy to forget when you are adding up a trip, so include them in your planning alongside accommodation and food. The Bangkok travel costs guide puts the everyday spending in context.
Once you are through: what to line up for the first days
With the paperwork done, it helps to have your first days sketched out so jet lag does not eat the time you have. Many visitors start with the Grand Palace, and booking a skip-the-line entry ticket for the Grand Palace ahead of time means one less thing to sort out on a tired first morning. For getting around the river without fuss, a bus and river boat pass is a simple way to cover several sights in a day.
These are optional extras, not entry requirements, and nothing here changes what the immigration rules ask of you.
Travelling with a partner, family or group
Entry rules apply to each person individually, so a mixed group can face different situations. Travellers with different passports may have different exemption rules, and you should check each person’s nationality separately rather than assuming the whole group is covered by the same rule. If one member of the group needs a visa and the others do not, that person needs to start the application well before the trip.
Parents travelling with children should be especially organised: separate TDAC forms, valid passports for everyone, and a folder, digital or paper, with confirmations and accommodation details. If you are travelling with older relatives, the Bangkok with elderly travellers guide and the Bangkok with kids guide cover what to expect once you are through immigration and on the road.
Official sources and keeping up to date
Because the day-count, the process and even the layout of the TDAC portal can change, the safest habit is to treat any article, including this one, as a starting point. Check the Thai embassy or consulate website for your country, and the official government portal for the arrival card, in the weeks before departure and again in the last few days. If your airline sends pre-travel emails about entry requirements, read them, because carriers are held responsible for passengers they carry who are refused entry.
Be sceptical of social media posts and forum threads quoting rules from a year ago. Rules that applied on a previous trip may not apply now, and a friend’s experience at the border is not a guarantee of yours. When official information and anecdote disagree, trust the official source and keep a note of where you found it.
A quick pre-departure checklist
Before you fly to Bangkok, confirm:
- Your passport is valid 6+ months from entry.
- You’re a visa-exempt nationality (or have arranged the right visa) — and you’ve re-checked the current day-count.
- You’ve completed the free TDAC for everyone in your party, within 72 hours of arrival, on the official portal.
- You have proof of onward travel and your accommodation details to hand.
With those squared away, entry at the airport is quick. The rest of your preparation — connectivity, packing, getting around — is covered in the Bangkok SIM and eSIM guide, the what to pack for Bangkok guide and the getting around Bangkok guide. First-time visitors should also read the Bangkok for first-timers guide, which covers what to expect on arrival.
