TDAC Thailand Form Guide

Official TDAC website: https://tdac.immigration.go.th

TDAC Guide is an unofficial helper app for travelers preparing the Thailand Digital Arrival Card, also known as TDAC.

This app is not affiliated with Thailand Immigration, any government authority, or the official TDAC website. TDAC Guide does not submit TDAC for you and does not replace the official TDAC website. Personal data and final submission must be completed only on the official TDAC website.

TDAC Guide is designed as a practical preparation tool before you open the official form. It helps you check your travel scenario, understand the main TDAC fields, prepare non-personal helper information, find address field suggestions, and create a local cheat sheet for easier form completion.

Main features:

• TDAC eligibility check
Use the main screen to choose your situation: entering Thailand, transfer only, or not sure. The app helps you understand whether you may need to prepare TDAC based on your travel scenario.

• Step-by-step preparation wizard
The app walks you through the main TDAC preparation sections: site language, personal information guidance, travel information, accommodation information, health declaration, and final review.

• Official site language matching
You can choose the language opened on the official TDAC website. The app can show field names as they may appear on the selected TDAC website language, while the app instructions remain in your chosen app language.

• Thailand Address Helper
The Address Helper helps with common accommodation address fields used in TDAC preparation, including Province, District, Sub-district, and Postal code. It includes local tourist area suggestions for popular places in Thailand.

Address suggestions are not your hotel’s official address. Always verify the information with your hotel voucher, booking confirmation, hotel website, or Google Maps before submitting TDAC.

• Readiness checklist
Use the interactive checklist to track what is ready before opening the official TDAC website: passport, arrival date, boarding country or territory, accommodation address, address fields, email for the official website, official website access, and saving QR/PDF after submission.

• Local cheat sheet
The app can create a local TDAC preparation cheat sheet with non-personal helper data, selected site language, selected address fields, and guidance notes. This cheat sheet is stored only on your device.

• Copy and share tools
You can copy a short version, copy a full version, or share the preparation cheat sheet through your device’s system share menu.

• Help and FAQ
The Help section explains common TDAC preparation topics, including transit cases, address fields, personal data safety, corrections, QR/PDF saving, and official website reminders.

Privacy and safety:

TDAC Guide does not ask you to enter your name, passport number, date of birth, email value, phone number, visa number, flight number, exact private address, document photos, geolocation, contacts, or account access.

The app stores only non-personal helper data locally on your device, such as selected language, selected address helper fields, readiness checklist progress, and saved cheat sheet guidance.

Important notice:

TDAC Guide is an unofficial preparation helper. It is not a government service, not an immigration service, and not an official TDAC submission tool.

Use the official TDAC website for final submission and all personal data entry:

Always verify current travel, visa, entry, health, and TDAC requirements through official sources before traveling.
