Thailand visa and TDAC: entry rules for Bangkok in 2026
Do I need a visa to visit Bangkok, and what is the TDAC?
Most Western nationalities (US, UK, EU, Canada, Australia and around 93 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.

Visa exemption: who enters visa-free, and for how long
Citizens of around 93 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.
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.
