Start with the official site and submission window

First check that the address bar shows tdac.immigration.go.th. This is the Thai Immigration Bureau’s official site and submitting TDAC is free. It is separate from the Thai e-Visa application website.

Complete it within three days before arrival, including arrival day. You need a new submission for every entry; a card from a previous holiday cannot be reused. Before starting, prepare your passport, inbound flight number, Thai local arrival date, English accommodation address and an email address for the document.

Reading the form in your preferred language

The examples below show the English mobile form. If someone travelling with you prefers another supported language, they can use the site’s language settings or their browser’s page translation. The location of these controls varies by phone and browser.

However you view the instructions, enter the details in English. Copy names and the passport number from the passport and the accommodation address from the English booking confirmation. The English screenshots below help you find the actual buttons and field labels.

Tap Arrival Card on the first screen

For a new submission, tap Arrival Card. The adjacent Update Arrival Card button is for changing an already submitted declaration. Start with Arrival Card if this is your first submission for the trip.

The home screen also contains notices about 90-day reporting and work permits. These do not mean that TDAC lasts for 90 days or gives permission to work in Thailand. Use Arrival Card to declare your arrival for this journey.

Personal Information: copy your passport details

Enter your surname in Family Name and given name in First Name. If your passport has no middle name, do not invent one to fill Middle Name. Match each name to its correct field, and copy the passport number into Passport No.

Nationality/Citizenship is your nationality; Date of Birth, Occupation and Gender ask for those personal details. Country/Territory of Residence is where you currently live, and City/State of Residence is your town or region. If you hold a British passport but live abroad, give your actual residence rather than automatically copying your nationality.

Visa No. is for the number of an issued visa. Do not invent a visa number if entering visa-free. Follow the required asterisks and distinguish optional fields. Phone No. separates the country code and telephone number. Tap Continue when you have finished.

Retrieve with Passport is unavailable in the screenshot below. If the passport MRZ-reading feature described in the official guide is not available, enter details manually from your passport. Even after an automatic scan, compare names and the passport number with the document.

Family Name / First Name

Surname / given name exactly as in your passport

Passport No.

Passport number

Nationality/Citizenship

Passport nationality

Country/Territory of Residence

Country where you currently live

City/State of Residence

Current town, city or region of residence

Visa No.

Issued visa number, if you have a visa

Arrival Information: enter the journey into Thailand

The travel stage separates Arrival Information and Departure Information. Start with Arrival Information and use your ticket. Find the local date and number of the flight landing in Thailand, rather than copying the date you leave the UK.

For a holiday on a regular passenger flight, choose HOLIDAY, AIR and COMMERCIAL FLIGHT. These choices describe that particular journey. Do not copy them for business, study or an entry by land or sea.

In a country search field, type the English country name or three-letter code, then select the matching item in the results. If boarding in the UK, search for the United Kingdom and choose the matching country. Typing a code alone is not enough: make sure the selected country appears in the field.

Date of Arrival

Thai local arrival date in YYYY/MM/DD format, using the ticket or calendar button. If arriving the day after departure from the UK, use that next day.

Country/Territory where you Boarded

The country where you board the flight into Thailand. For a direct flight from the UK, choose the UK; after a connection, use the country where you board the Thailand-bound flight.

Purpose of Travel

Choose HOLIDAY for a holiday. Use MEETING, BUSINESS or EDUCATION only for the actual purpose. OTHERS (PLEASE SPECIFY) needs the requested explanation in English.

Mode of Travel

AIR for a flight, LAND for a land entry and SEA for a boat. The transport choices below depend on this answer.

Mode of Transport

COMMERCIAL FLIGHT for a regular passenger flight. Choose PRIVATE/CARGO AIRLINE or OTHERS only where applicable.

Flight No./Vehicle No.

The airline code and flight digits on the ticket for arrival in Thailand, not the booking reference or seat number. For land or sea entry, use the details of your actual transport.

Departure Information: enter your journey out of Thailand

Below the arrival details is Departure Information. These dates and flight numbers describe leaving Thailand, rather than leaving the UK. For a return flight, copy the Thai local departure date and flight number from the return ticket.

The captured form does not mark departure details with required asterisks. If you have not fixed these details, do not invent a date or flight number. An optional field is separate from the need to demonstrate return or onward plans at immigration.

Use Clear to remove an incorrectly chosen departure travel mode. Read the section heading so you do not confuse arrival AIR with departure AIR.

Date of Departure

The local date you leave Thailand, not the date you reach the UK.

Mode of Travel

AIR, LAND or SEA for your departure. It can differ from your arrival mode.

Mode of Transport

The actual transport matching your departure mode. A regular return passenger flight is COMMERCIAL FLIGHT.

Flight No./Vehicle No.

The flight or vehicle number leaving Thailand. Compare it with your outbound ticket rather than copying the arrival flight.

Clear

Resets an incorrectly selected departure travel mode.

Accommodation Information: use your booking address

Open your booking confirmation and find the accommodation’s English address. This stage asks where you will stay in Thailand, not your home address in the UK. Copy the location and address from the booking or the property’s official details rather than relying on its name alone.

Required fields may change with the accommodation type. In the captured form, choosing HOTEL removed the required asterisks from District and Sub-District. Do not assume every accommodation type behaves the same way: follow the asterisks on your own form.

Choose Province first, then District, Area, then Sub-District, Sub-Area to make the lower-level lists available. Choose the location matching the property’s address, even where names are similar. For accommodation in Bangkok, select BANGKOK as the province.

I am a transit passenger, I don’t stay in Thailand concerns transit passengers who will not stay in the country. Do not choose it simply because you have no hotel booking. It may be unavailable depending on previous selections; if entering Thailand for a holiday stay, enter your actual accommodation.

Type of Accommodation in Thailand

Choose the real type: HOTEL, YOUTH HOSTEL, GUEST HOUSE, FRIEND’S HOUSE or APARTMENT. If using OTHERS, give the requested explanation.

Province

The province or Bangkok-level area in the accommodation address, not the airport’s location.

District, Area

Choose the area in the property’s address after selecting Province. Whether it is required depends on the accommodation type.

Sub-District, Sub-Area

Choose the smaller administrative area in the address. Select the higher-level area first to enable the list.

Post Code

The property’s Thai postcode. Compare any automatically filled value with the booking; if entering it manually, use the property’s own code. The captured form has no required asterisk here.

Address

Enter the property name and actual English building, street number and road address. Selecting a region does not complete the detailed address. The captured field shows a 215-character limit: retain the hotel name and real location information when arranging a long address.

Health Declaration: countries visited in the previous two weeks

The health stage asks for countries or territories where you stayed during the two weeks before arrival. If travelling directly after staying in the UK, select the UK; if you also stayed elsewhere in that period, include your actual history. This is not a list of Thai cities you intend to visit.

Type the English country name or code and select the matching result. Passport nationality, residence, the country where you boarded your Thailand flight and recent stays are different questions. Do not automatically copy the same country into every field when travelling through several countries.

A vaccination notice referring to Ministry of Public Health requirements appears above. The official guide says additional health information may be requested depending on recent countries, boarding country, nationality or flight. Answer the questions and document requests actually shown for you. The captured basic screen followed a Korea example and does not establish which extra fields a British traveller will see.

Tap Preview after completing the details. Previous returns to the preceding stage; Add Other Travelers adds another person. Do not substitute one traveller’s country history for another person’s.

Countries/territories where you stayed within two weeks before arrival

Select the countries and territories where you actually stayed in the two weeks before entering Thailand, not future destinations or the passport issuing authority.

Additional health information or documents

Read the questions and applicable conditions on your screen and give your actual health and travel information. Do not copy answers from a different example.

Preview / Previous / Add Other Travelers

Review the form, return to the previous stage or add a companion. Use each person’s own passport and travel details.

Preview: enter your email and review before submitting

Read the names, passport number, nationality and date of birth again, together with arrival date, boarding country, inbound flight and accommodation address. Use Edit to correct mistakes. EXAMPLE in the screenshot is a demonstration: it was not submitted as a real arrival declaration.

Enter an email address you can receive messages at in the email field at the bottom. It is not a name field: check the spelling on both sides of @. Using an inbox you can open on that phone makes the document easier to find afterwards.

Read the Terms and conditions. If you agree, tick the box yourself and tap Submit. The submit button remains unavailable without the agreement. Opening Preview does not finish your submission.

If submission returns an error or no completed document appears, do not assume it succeeded. Look for the completion message and actual TDAC document before saving it.

Edit

Return to the relevant entry stage to correct an error found during review.

Please specify an email to send Thailand Digital Arrival Card

Enter a working email address and read it again before submission so you can find the document.

I have read and accepted the Terms and conditions

Read the linked terms and tick the box yourself only if you agree.

Submit

Submit after reviewing the details, adding the email and completing the required agreement. Then look for the completion message and document.

After submission: download TDAC to your phone

A successful submission provides a completion message and TDAC download. The official video shows both the completion screen and document. The image below is an example from that official video, captured in a mobile browser. The video contains an older desktop example, so its layout may differ from the current mobile form.

After downloading, compare the name, passport details and arrival date with your own journey. Keep the card number and any QR code shown with your document, and find the emailed copy too. Do not use the example number or QR code from the video as your own entry document.

Save the downloaded file so you can open it without an internet connection. Keeping the actual file rather than just an email link makes it accessible if the airport connection is unreliable. You can carry a printed copy if needed.

Keep the document ready to show on arrival and retain it during your stay. A completed TDAC is not a visa or entry permission. Your visa or exemption conditions and immigration clearance remain separate.

Completion message

Look for confirmation of successful submission; a preview alone is insufficient.

TDAC download

Save the completed document in your phone’s files. Check that it opens with the internet switched off.

Card number, traveller details and QR code

Check your own name, passport and arrival date and retain the confirmation. Do not use the official video’s sample as a real entry document.

Emailed document

Find the confirmation in the email address used at submission. Download or print it if needed.

Changing an already submitted TDAC

Tap Update Arrival Card on the first screen. The captured search screen asks for the TDAC number, date of birth, arrival date and nationality. Use your document and passport to fill these in, then tap Search.

The official FAQ says passport name, passport number, nationality and date of birth cannot be changed. If one of these is wrong, submit a new form with the correct information. Update eligible details such as accommodation before entering Thailand, resubmit and save the replacement document.

The screen below searches for an existing submission. If you have not submitted a form, return to Arrival Card and start a new one rather than looking here for a TDAC number.
