Need help understanding the Thailand Digital Arrival Card (TDAC) process? Use this contact page for TDAC application guidance, document preparation, status-check questions, update support, missing confirmation issues, family/group travel questions, and general Thailand arrival guidance.

TDAC is required for non-Thai nationals entering Thailand, and the official TDAC guide says travelers should submit their arrival card information 3 days before arrival in Thailand. The official TDAC website also states “No Fees,” so travelers should understand that the official government TDAC process is free.

Important Notice

Thailand Digital Arrival Card (TDAC) is an independent informational and traveler assistance Google Site. This site helps travelers understand TDAC requirements, documents, timing, updates, status checks, and common travel issues.

This site is not the official Thai Immigration website, not a government authority, and not affiliated with Thai Immigration, any embassy, or any government department.

Travelers may complete the official TDAC process directly through the official Thai Immigration Bureau system. Any independent support fee, if applicable, should be clearly disclosed as a service or assistance fee — not as a Thai government fee. The official TDAC website states “No Fees.”
