Start with the official site and submission window

Check that your address bar reads tdac.immigration.go.th. This is the Thai Immigration Bureau’s official website, and TDAC submission is free. It is a separate site from Thai e-Visa.

Submit within the three days before arrival, including the arrival date. You need a new TDAC every time you enter Thailand; a card from a previous trip cannot be reused. Before starting, have your passport, incoming flight number, local Thailand arrival date, accommodation address in English and email ready.

Read the form in the language you prefer

The site provides language settings, and your phone’s browser may also offer page translation. These controls can appear in different places depending on the phone and browser. English-speaking travelers can use the original English form shown below.

Whichever display language you choose, enter the details in English. Copy names and passport numbers from the passport, and use your accommodation’s English booking address. The mobile screenshots below retain the English button and field names so you can find each step.

Choose Arrival Card on the opening screen

For a new submission, select Arrival Card. The neighboring Update Arrival Card button is for changing a record you have already submitted. Start with Arrival Card when you have not yet submitted this trip.

The opening screen also mentions 90-day reporting and work permits. This does not mean TDAC lasts for 90 days or gives you permission to work. Complete this trip’s arrival declaration through Arrival Card.

Personal Information: use your passport details

Enter your surname under Family Name and your given name under First Name. If you do not have a middle name in your passport, do not invent one to fill Middle Name. Put each part of the name in its matching field and copy the passport number into Passport No.

Nationality/Citizenship asks for citizenship; Date of Birth, Occupation and Gender ask for your birth date, occupation and gender. Country/Territory of Residence is where you currently live, and City/State of Residence is your city or state. A U.S. citizen living overseas should enter actual citizenship and residence separately.

Visa No. is for a visa already issued to you. If entering visa-free, do not invent a visa number. Follow the asterisks to distinguish required fields from optional ones. Phone No. separates the country code from your phone number. Select Continue after completing the page.

In the retained screenshot, Retrieve with Passport is unavailable. If the MRZ-reading feature described in the official guide is not available, enter your details manually. Even when it does read your passport, compare the names and passport number against the document.

Family Name / First Name

Surname and given name exactly as shown in your passport

Passport No.

Your passport number

Nationality/Citizenship

The nationality of your passport

Country/Territory of Residence

Your current country of residence

City/State of Residence

Your current city or state

Visa No.

The number of your issued visa, if you have one

Arrival Information: enter the flight arriving in Thailand

The trip stage has separate arrival and departure information for Thailand. Start with Arrival Information and look at your ticket. Find the local Thailand arrival date and incoming flight number, rather than copying the date you left the United States.

For a vacation arriving on a regular passenger flight, choose HOLIDAY, AIR and COMMERCIAL FLIGHT. These answers describe air travel for a holiday; business, study, land and sea arrivals must reflect their actual circumstances.

Type the English country name or three-letter code, then select the matching result from the list. If you boarded the Thailand-bound flight in the United States, search for USA and select USA : THE UNITED STATES OF AMERICA. Typing a code without choosing its list entry may not set the country.

Date of Arrival

Enter the local Thailand arrival date from your ticket in YYYY/MM/DD format, or use the calendar. It can differ from your U.S. departure date.

Country/Territory where you Boarded

Select the country where you boarded the flight to Thailand. For a nonstop U.S. departure, choose USA : THE UNITED STATES OF AMERICA. If you connect abroad, use the country where you board that Thailand-bound flight.

Purpose of Travel

Choose HOLIDAY for a vacation. Use MEETING, BUSINESS or EDUCATION only when they match the trip. OTHERS (PLEASE SPECIFY) requires an explanation in English.

Mode of Travel

Select AIR for a flight, LAND for a land crossing or SEA for a sea arrival. This choice changes the transport options below.

Mode of Transport

Choose COMMERCIAL FLIGHT for a regular passenger flight. PRIVATE/CARGO AIRLINE and OTHERS apply only when they describe your actual transport.

Flight No./Vehicle No.

Copy the airline code and number of the flight arriving in Thailand. This is not a reservation code or seat number. Land and sea travelers enter the relevant transport details.

Departure Information: enter your trip out of Thailand

Below the arrival fields is Departure Information. Its date and flight number concern leaving Thailand, rather than leaving the United States. With a round-trip ticket, copy the local Thailand departure date and flight number of your return flight.

Departure fields have no required asterisk in the retained screen. If you do not yet have a departure plan, do not make up dates or flight numbers. An optional form field does not remove the need to explain your return or onward plans at immigration.

Use Clear to remove a departure travel mode chosen by mistake. Read the section headings carefully so you do not confuse the arrival AIR option with departure AIR.

Date of Departure

The local date you leave Thailand, which may differ from the date you arrive back in the United States.

Mode of Travel

Choose AIR, LAND or SEA for the way you leave Thailand. Arrival and departure modes can differ.

Mode of Transport

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

Flight No./Vehicle No.

Enter the flight or vehicle number leaving Thailand. Compare it with the return ticket rather than copying the arrival flight.

Clear

Resets an incorrectly selected departure travel mode.

Accommodation Information: copy your reservation address

Open your hotel reservation and find the English accommodation address. This is where you will stay in Thailand, rather than your U.S. home address. Use the booking or hotel’s official address so the place name and administrative areas match.

Required fields may change with accommodation type. In the retained screen, selecting HOTEL removes the required asterisks from District and Sub-District. Follow the asterisks on your own form rather than assuming every accommodation type works the same way.

Select Province first, then District, Area, then Sub-District, Sub-Area to make the lower lists available. Choose entries matching the actual hotel address even when names look similar. For accommodation in Bangkok, Province can be BANGKOK.

I am a transit passenger, I don’t stay in Thailand concerns transit without a stay. Do not select it simply because you have not booked a hotel. It may be disabled depending on earlier answers. If you are entering Thailand for a stay, provide the actual accommodation details.

Type of Accommodation in Thailand

Choose HOTEL, YOUTH HOSTEL, GUEST HOUSE, FRIEND’S HOUSE or APARTMENT to match your stay. Give the requested explanation when choosing OTHERS.

Province

Select the province or Bangkok area containing your accommodation, rather than the location of the airport.

District, Area

Choose the district in the hotel’s address after selecting Province. Whether it is mandatory depends on the accommodation type.

Sub-District, Sub-Area

Choose the smaller administrative area shown in the address. Select the parent district before using this list.

Post Code

Use the accommodation’s Thai postal code. Compare any automatically filled code with the booking. This field has no required asterisk in the retained screen.

Address

Enter the property name and actual building number, street and English address. Choosing administrative areas does not complete the street address. The retained field shows a 215-character limit, so keep the property name and real location information when arranging a long address.

Health Declaration: countries visited in the past two weeks

The health declaration asks for countries or territories where you stayed during the two weeks before arrival. If you have been living in the United States and leave directly, select the United States. Include any other countries where you actually stayed during that period. This field is not for Thai cities you plan to visit.

Type an English country name or code and choose the matching result. Citizenship, residence, the country of boarding and recent stays are different questions. If you are traveling between countries, do not automatically copy the same country into every field.

A vaccination notice refers to Thai Ministry of Public Health requirements. The official guide explains that additional health information may be requested depending on recent countries, boarding country, nationality or flight. Read and answer the questions shown for your own journey. The retained screenshot illustrates a route using Korea and does not establish that every traveler sees identical extra fields.

Select Preview when you finish. Previous returns to the preceding step, while Add Other Travelers adds another traveler’s record. Use each person’s actual travel history rather than copying one traveler’s countries to everyone.

Countries/territories where you stayed within two weeks before arrival

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

If additional health questions or evidence are requested

Read the displayed requirements and provide your own actual health and travel details. Do not copy answers from an example with different eligibility.

Preview / Previous / Add Other Travelers

Preview reviews entries, Previous returns to the prior step and Add Other Travelers adds another person. Use each traveler’s passport and actual trip details.

Preview: review your details and enter your email

Review your name, passport number, nationality and birth date, plus arrival date, boarding country, arrival flight and accommodation address. Use Edit to correct anything wrong. EXAMPLE in the screenshot is demonstration data; no actual declaration was submitted.

Enter an email address you can receive mail at in the email field near the bottom. It is not a name field: read the spelling and both sides of the @ sign. Being able to open that inbox on your phone makes it easier to find the completed document.

Read Terms and conditions, check the box if you agree and choose Submit. The submission button is disabled without the required agreement. Reaching Preview does not complete submission.

If an error appears or the completed document does not show, do not treat the declaration as successfully submitted. Look for the actual success notice and TDAC document before saving them.

Edit

Return to the entry step to correct an error found during review.

Please specify an email to send Thailand Digital Arrival Card

Enter a working email address and reread it before submission; a typo can make the document hard to find.

I have read and accepted the Terms and conditions

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

Submit

Submit after review, email entry and the required agreement. Then look for confirmation and the actual document.

After submission: save the TDAC document to your phone

After successful submission, look for the success notice and TDAC download. The official video shows both. The retained image is a completion example from that official video, captured in a mobile browser. The video itself uses an older desktop screen, so its layout can differ from the current mobile form.

Download your document and compare the name, passport information and arrival date with your trip. Keep the declaration number, QR code and other confirmation details, and find the emailed copy too. Never use the sample number or QR code in the video as your own arrival document.

Save the file on your phone so it opens without internet access. Keeping the actual file, rather than just an email link, helps when the arrival airport connection is unreliable. You can also bring a printed copy if useful.

Have the confirmation available at entry and keep it during your stay. TDAC confirmation is not a visa or permission to enter. You still need to satisfy your visa or exemption conditions and pass immigration.

Success notice

Look for an actual successful-submission message, rather than the preview shown before submission.

TDAC document download

Save the completed file to your phone and make sure you can open it with the internet off.

Declaration number, traveler details and QR code

Compare your name, passport details and arrival date with your trip. Do not use the video’s sample document for entry.

Document received by email

Keep the emailed confirmation too. Download or print it if needed.

Updating a TDAC you already submitted

Choose Update Arrival Card from the opening screen. The retained search screen asks for the TDAC number, birth date, arrival date and nationality. Fill them in using your confirmation and passport, then select Search.

The official FAQ says passport name, passport number, nationality and birth date cannot be changed and advises a new form with correct details for those errors. Its release history separately states that passport-number editing was enabled; these statements conflict. For an incorrect passport number, seek clarification from Immigration rather than relying on an assumed editing rule. Correct other editable information, such as accommodation, before entry, resubmit and save the resulting document.

This screen searches for a declaration already submitted. If you have not submitted one yet, return to Arrival Card and start a new declaration instead of looking for a TDAC number.
