TDAC.info — Thailand Digital Arrival Card Help

TDAC.info is an independent help hub dedicated to one thing: making the Thailand Digital Arrival Card (TDAC) painless to fill in. Every traveler arriving in Thailand by air, land, or sea must submit the TDAC within 72 hours of arrival, and the official form — while free — trips up thousands of visitors every week with small ambiguities around accommodation addresses, transit stops, occupation codes, and uploaded documents. TDAC.info walks through the form field-by-field, in the traveler's own language, with screenshots and real-world examples.

What the site actually does

The core of TDAC.info is a guided walkthrough of the official Thailand Pass / Digital Arrival Card submission process. Nothing is submitted through the site itself — the final submission always happens on the official Thai Immigration portal. What the site adds is context: which fields trip people up, what to enter when you're staying across multiple hotels, how to handle a cruise arrival, what to do if your passport was recently renewed, and dozens of other scenarios that the official form doesn't explain well. Content is available in 30+ languages and updated whenever the Thai Immigration Bureau changes the form.

Who uses it

TDAC.info is used primarily by leisure travelers heading to Thailand from Europe, North America, East Asia, India, and the Middle East, as well as long-stay visitors extending or switching visas inside the country. Families submitting for multiple passports, expats returning after a border run, and business travelers on tight connections all tend to land on the site when the official form surfaces an unclear error. The site does not charge for any of its guides — its value sits squarely on the help side rather than on paid submission services.

Why it's relevant to Bangkok visitors

Roughly 40% of Thailand's international arrivals transit through Bangkok's Suvarnabhumi and Don Mueang airports, which makes the TDAC the first piece of Thai paperwork most Bangkok-bound travelers encounter. Getting it right before the flight prevents the most common cause of queue delays at immigration: being pulled aside to complete the form on arrival. For anyone planning a Bangkok trip and Googling around the arrival card, TDAC.info is typically the clearest, most complete English-language resource available.
