Thailand Visa Requirements – Everything You Need to Know Before You Go

Do You Need a Visa for Thailand?

The answer depends on your nationality and how long you plan to stay. Thailand has three main entry pathways for tourists.

Visa Exemption – The Most Common Route

Citizens of 93 countries and territories can enter Thailand without applying for a visa in advance – including the US, Canada, UK, all EU countries, Australia, New Zealand, Japan, South Korea, Singapore, Malaysia, UAE, Israel, and Qatar.

Under the visa exemption scheme, eligible travelers can stay for up to 60 days, with the option to extend once at an Immigration Office in Thailand for an additional 30 days at a fee of 1,900 THB.

Important 2026 update: Thailand now allows two visa-exempt entries per calendar year. Since November 2025, immigration officers can deny entry after two exemption entries without a justifiable reason. Officers may also question travelers who have used visa exemptions in previous calendar years, even if the current year’s count has reset. If you have a history of frequent Thailand entries, applying for a tourist visa before travel is strongly recommended.

Additionally, Thailand’s Ministry of Foreign Affairs has proposed reducing visa-exempt stays from 60 days to 30 days, citing security concerns. No official change has been enacted as of early 2026, and the 60-day stay remains in force – but travelers should monitor updates before booking.

Visa on Arrival

Citizens of certain countries may apply for a Visa on Arrival at designated Thai international airports and border checkpoints, typically allowing a stay of up to 15 days. Arrive prepared with all documentation, as processing times vary with airport traffic.

Tourist Visa – For Longer or Multiple Stays

The Thailand Tourist Visa is available in two types. The Single-Entry Tourist Visa allows up to a 60-day stay. The Multiple-Entry Tourist Visa is valid for six months with a 60-day stay limit per visit. You can apply through a Royal Thai Embassy, Consulate, or Thailand’s e-Visa system. Contact the embassy you will be applying from beforehand, as some have moved to exclusively digital applications.

Destination Thailand Visa – For Digital Nomads and Remote Workers

The Destination Thailand Visa is a long-term option for remote workers and freelancers. It remains valid for five years with multiple entries and allows stays of up to 180 days per visit, extendable once per entry for a further 180 days at a fee of 1,900 THB. The Thai e-Visa system is now accessible at all Thai embassies and consulates – in most cases, you no longer need to visit in person.

Documents to Carry at Immigration

Regardless of visa type, have the following accessible at Thai immigration:

• Passport – valid for at least six months beyond your arrival date in Thailand. Airlines may refuse boarding if this is not met.
• Return or onward ticket – digital or printed proof of departure from Thailand. One-way ticket holders may be asked to explain travel plans.
• Proof of accommodation – hotel booking confirmation or private accommodation address.
• Proof of funds – a bank statement showing at least 10,000 THB per person or 20,000 THB per family. Officers rarely ask for this on standard tourist entries, but having it removes any risk.
• Thailand Digital Arrival Card (TDAC) – mandatory for all non-Thai nationals since May 2025. Covered in full in the next section.

The Thailand Digital Arrival Card (TDAC) – What It Is and How to Fill It

This is the most important procedural change to Thailand’s entry in 2026. The paper TM6 arrival card you used to fill in on the plane no longer exists. The TDAC is its mandatory digital replacement, and missing it will result in denied boarding or immigration delays.

What Is the TDAC?

The Thailand Digital Arrival Card is an online form that replaces the paper-based arrival card for all modes of entry – air, land, and sea. It is designed to strengthen security, streamline immigration, and support public health management. Every non-Thai national must complete it before entering the country. That includes tourists, visa-exempt travelers, business visitors, long-term visa holders, returning expatriates, and children, including infants.

The TDAC is not a visa. Completing it does not guarantee entry – it is an entry requirement in addition to whatever visa applies to your nationality.

There is no fee. The TDAC is free. Any website or service charging you for TDAC submission is a scam. The only legitimate channel is: tdac.immigration.go.th

When to Submit?

The TDAC can only be submitted within 72 hours – three days – before your arrival date in Thailand. The system will not allow you to enter a date more than 72 hours away. The recommended window is one to two days before your flight, giving you time to fix any errors without airport pressure.

Group submissions of up to 10 travelers are allowed in a single submission, useful for families or group trips.

Step-by-Step – How to Fill the TDAC

• Step 1 – Go to the official portal Visit tdac.immigration.go.th and click “Arrival Card.” Do not use any third-party website or app.
• Step 2 – Enter personal information Fill in your details exactly as they appear in your passport. The system supports scanning the MRZ – the two-line machine-readable code at the bottom of your passport photo page – or uploading an MRZ image to auto-fill the fields. Verify every field after auto-fill and continue. All details must be entered in English.
• Step 3 – Enter trip and accommodation information. Enter your arrival date, flight number, and accommodation address in Thailand. You need a full address – hotel name, street number, street name, sub-district, district, province, and postal code. Your hotel booking confirmation is the easiest source for this. “Bangkok” alone is not sufficient and will flag an error.
• Step 4 – Complete the health declaration. Declare your travel history from the previous 14 days. If you have visited any countries flagged by Thailand’s Ministry of Public Health, the system will prompt additional health questions before you can proceed.
• Step 5 – Review everything carefully. Once submitted, you cannot edit core personal details, including name, passport number, date of birth, or nationality. Only minor updates, such as flight time are permitted after submission. Check every field before clicking submit.
• Step 6 – Enter your email and submit. Enter a valid email address – this is the only way to receive your QR code and confirmation PDF. Accept the terms and conditions and submit.
• Step 7 – Download and save your TDAC. A PDF with your QR code is sent to your email within minutes. Save it offline on your phone and keep a printed backup. You will need this at airline check-in and at Thai immigration.

Common TDAC Mistakes to Avoid

• Wrong passport number – critical. Submit a new application immediately if this happens. The system links the TDAC to your passport number and mismatches result in you not existing in the immigration system on arrival.
• Wrong arrival date – use the date your flight lands in Thailand, not the date it departs your home country. An overnight flight leaving on the 1st that arrives on the 2nd should have the 2nd as the arrival date.
• Incomplete accommodation address – hotel name alone will not pass. Include the full address with district and postal code.
• Third-party websites – no mobile apps, no third-party services, no paid submission portals are authorised. If a website charges you for TDAC submission, it is not legitimate.

At the Airport – What to Expect?

Have your TDAC QR code and passport ready for airline check-in before your flight and for immigration on arrival. Keep the QR code saved in your phone’s photo gallery for offline access – you do not want to rely on an internet connection at the immigration counter.

If you have not completed your TDAC before arrival, major international airports, including Suvarnabhumi, Don Mueang, Phuket, Chiang Mai, and Hat Yai, have on-site TDAC kiosks and free Wi-Fi. That said, completing it before your flight removes the risk entirely.

Why Voye Global Is the Better Choice for Most Travelers?

Local SIMs work well in Thailand – but they come with friction that a Voye Global eSIM removes entirely. Here is what changes when you choose Voye for your Thailand trip.

• You set it up before you fly. A Voye Thailand eSIM is purchased online, delivered to your email as a QR code, installed in under five minutes, and ready to activate the moment you land. No SIM counter, no queue after a long-haul flight, no passport registration at the airport. Your connectivity is sorted from the sofa before you board.
• Your home SIM stays active. A Voye eSIM is digital and runs alongside your existing home SIM. Your home number remains active throughout the trip – for banking authentication, two-factor verification codes, and staying in contact with family. A physical Thai SIM requires you to remove your home SIM or manage dual-SIM settings, creating the risk of missing important calls or verification messages while you are away.
• Transparent unlimited terms – no surprises. Voye discloses the 3GB daily high-speed cap on the plan page before purchase. After the daily cap, speeds reduce but your connection stays on and basic functions remain available. The cap resets at midnight each day. There is no hidden fair-use threshold, no undisclosed speed drop waiting to happen mid-trip. With local Thai operators, the fair-use terms vary by plan and are not always clearly stated before purchase.
• Unrestricted hotspot on every plan. Every Voye Thailand plan supports hotspot tethering without a daily ceiling. Connect a laptop in a café, share data with a travel companion, or keep a tablet connected on a long bus journey between destinations – the full plan allocation is available for tethering with no separate hotspot limit applied on top.
• Multilingual support at any hour. Voye’s 24/7 WhatsApp support connects you to a real person in multiple languages – no bot queue, no business-hours limitation. Thai local operators provide support primarily in Thai and English, through in-store visits or local hotlines. If something goes wrong at midnight in Chiang Mai and English is not your first language, the difference matters.
• Both fixed data and unlimited options. Whether you want a known data allowance at full speed throughout your stay or an unlimited plan for a longer or higher-usage trip, Voye offers both. Choose the plan that fits your trip length and data habits, with clear pricing and no hidden conditions.

Voye Global Thailand Plans

Voye Global offers both fixed data and unlimited plans for Thailand. Fixed data plans give you a known allowance at full speed throughout the validity period – ideal for travelers who want predictable costs and moderate daily usage. Unlimited plans deliver 3GB of full-speed data per day with speeds reduced after the daily cap – designed for heavy users, digital nomads, and remote workers who need consistent connectivity across a longer stay.

Both plan types are available across a range of durations starting from a few days through to 30 days, with top-ups available at any time without reinstalling the eSIM. Confirm current plan prices and data options at voyeglobal.com.

The TDAC is the mandatory online replacement for the old paper TM6 arrival card. All non-Thai nationals must complete it before entering Thailand by air, land, or sea, regardless of visa status. It is completed at tdac.immigration.go.th and is completely free.
