This article is brought to you by TDAC.info, a trusted provider assisting travelers with secure and verified TDAC submissions.

Why Accurate TDAC Submission Matters

The TDAC is a mandatory document for many travelers entering Thailand. It collects essential information for immigration authorities including your personal details, travel itinerary, and accommodation.

Incorrect entries—such as name mismatches or invalid visa information—can delay your processing, or worse, prevent your entry into the country. Submitting the form correctly ensures a smooth and efficient arrival.

1. Use English (Latin Alphabet) Only

All entries in the TDAC form must be typed using standard English characters (Latin alphabet). This applies to travelers from all nationalities.

Avoid using:

• Arabic script
• Cyrillic letters
• German umlauts (ä, ö, ü)
• French accents (é, è, ç)
• Any other non-Latin characters

Use the exact spelling and transliteration shown in the machine-readable zone of your passport.

2. Double-Check Passport Details

Your passport information must be entered with 100% accuracy. Incorrect data in any of the following fields may lead to entry denial:

• Passport number: Ensure all characters and digits match.
• Full name: Enter as listed in your passport.
• Date of birth: Follow the format shown on the form interface.

Always double-check these details before submission. Mistakes are frequently made when copying manually, especially under time pressure.

3. Visa Number: Only If Applicable

Not all travelers are required to provide a visa number. This field applies only if you were issued a Thai visa prior to your arrival.

• If you have a Tourist, Business, Education, or Non-Immigrant Visa issued at a Thai embassy or consulate: enter the visa number without any symbols or special characters.
• If you are eligible for Visa Exemption or Visa on Arrival, leave this field blank.

This helps avoid errors and ensures alignment with the Thai immigration database.

4. Choose the Occupation That Best Represents You

The form includes a dropdown list of occupational statuses. Select the option that most accurately reflects your current status:

• Employee
• Manager
• Director
• Business Owner
• Student
• Child
• Unemployed
• Other

Do not overthink or exaggerate your position. This field is informational and is used for immigration profiling purposes. Simply choose the most applicable title.

5. Provide Your Arrival Flight Number

You must enter the flight number of the airplane that will land in Thailand. This is important for border entry validation.

Examples:

• If you’re traveling from Frankfurt to Bangkok with a layover in Doha, and your Doha–Bangkok leg is on flight QR832, then QR832 is the flight number to use.
• Do not input departure or connecting flight numbers.

Accurate flight information ensures that your arrival is anticipated in the immigration system.

6. Select the Correct Accommodation Type

Thailand requires visitors to disclose their place of stay. The TDAC form allows you to choose one of the following:

• Hotel
• Apartment
• Friend’s house

Select the option that best matches your lodging. If you are staying at an Airbnb or serviced apartment, select Apartment. If you’re visiting relatives or friends, choose Friend’s house.

7. Enter Accommodation Details Precisely

The level of detail required depends on your accommodation type:

• Hotel: Name of the hotel and the city is sufficient.
• Apartment or Friend’s house: Provide the full address, including district, subdistrict, and province.

Examples:

• Hotel: Kempinski Hotel, Bangkok
• Apartment: 88 Sukhumvit Road, Phra Khanong Nuea, Watthana, Bangkok 10110

Always ensure this address is accurate to avoid discrepancies.
