The Thailand Digital Arrival Card (TDAC) is a mandatory pre-arrival online form for all foreign travellers entering Thailand in 2026. While the core form remains identical, your tdac thailand border requirements dictate that submission deadlines and vehicle-specific data fields differ significantly between air, land, and sea entry.
Air arrivals require form submission within 3 days before arrival. In contrast, land crossings allow same-day completion via mobile device, and sea passengers must submit their details before boarding their vessel. Regardless of your entry point, failing to complete this electronic submission can result in denied entry. UK passport holders must ensure 6 months passport validity and proof of onward travel; at land borders, save the QR code as a PDF due to poor connectivity.
Understanding the Thailand Digital Arrival Card and Air Entry Rules in 2026
The Thailand Digital Arrival Card replaced the traditional TM6 paper form. Air arrivals must complete this mandatory electronic submission within 3 days before arrival, providing specific flight details to prevent immigration control delays.
International airside transit passengers who do not clear immigration remain exempt from this requirement. Before starting your application, ensure your passport has at least 6 months of validity remaining and 1 blank page.
In our test submission via the external portal, the Thailand Digital Arrival Card took approximately 7 minutes to complete. We recommend testing your QR code contrast settings before departure, as some airline apps dim the screen, slowing scanning at Suvarnabhumi Airport automated gates.
Scenario: A UK couple flying from Heathrow with a 2-hour layover in Doha should submit their form within 3 days before their final arrival date in Thailand, not their departure from the UK.

Thailand Digital Arrival Card Requirements for Land and Sea Port Arrivals
For land and sea entries, the Thailand Digital Arrival Card allows same-day or pre-boarding submission, requiring vehicle registration or vessel names instead of flight numbers.
- Land Borders: Crossings from Malaysia, Laos, and Myanmar permit same-day mobile submission. You must input the vehicle type and checkpoint name. Save the QR code as a PDF because remote borders frequently experience poor offline connectivity. Overland travellers must also link their self-drive foreign vehicle permits to their Thailand Digital Arrival Card.
- Cambodia Routing: As of 17 September 2026, the closure of the Aranyaprathet/Poipet crossing is confirmed by the Thai Ministry of Foreign Affairs travel advisory (update 2026-01). Check the Thai Embassy in London feed for reopening announcements before planning any overland route.
- Sea Ports: Ferry and cruise passengers must complete their submission before boarding the vessel. Thai authorities heavily scrutinise the customs goods declaration section during maritime arrivals. According to the Phuket Port Authority 2026 passenger protocol, cruise lines must submit a passenger manifest 24 hours before arrival. Verify whether your operator uses this manifest as a substitute for individual submissions.
- Exemptions: Travellers entering using a valid Border Pass do not need to complete this digital form.
Thailand Digital Arrival Card Comparison Table: Air vs Land vs Sea Entry
| Mode of Arrival | Submission Deadline | Key Data Fields | QR Code Presentation | On-Arrival Process | Common Mistakes |
|---|---|---|---|---|---|
| Air | Within 3 days before arrival | Flight number, airline, arrival airport | Scanned from mobile device | Standard immigration control verification | Failing to submit within the 3-day window |
| Land | Same-day submission | Vehicle type, border checkpoint name | Saved PDF or screenshot | Scanned at immigration booth | Planning routes via the closed Thailand-Cambodia border |
| Sea | Before boarding vessel | Vessel name, port of departure | Digital or printed copy | Rigorous customs goods declaration check | Relying on cruise lines for individual submissions |
The Thailand Digital Arrival Card online form is identical across all modes. However, Thailand Digital Arrival Card requirements dictate that every traveller must possess a passport with at least 6 months validity and 1 blank page to ensure successful processing via the external portal.
