The complete Thailand Digital Arrival Card guide for first-time visitors

What the card actually is

The Thailand Digital Arrival Card is an electronic entry form, not a travel permit. It replaced the paper card that used to be handed out on planes and at border posts. It records four things: who you are (passport details), how you are arriving (flight or crossing, date), where you will spend your first night, and a few standard health questions. Thai immigration reads it at the counter when you enter - by air, land or sea.

It is required for every foreign traveller, regardless of visa status, and it is filed free of charge on the official government portal. Paid private services exist, but they charge for assistance, not for the card itself - see Official Channels.

The 72-hour window

This is the rule that catches most first-timers. The card can only be filed in the 72 hours before you arrive in Thailand. Not a month ahead when you book, not a week ahead when you check in - three days, maximum.

Why so narrow? Because the card is tied to your actual arrival: your flight, your arrival date, your first night's address. File too early and your plans may change; the system wants a card that matches your real trip.

Practical consequences:

• Long-haul with connections? Your window may open while you are already in the air.
• Crossing by land from Malaysia or Laos? The window opens while you are still on the road.
• Plans changed after filing? File a new card - each entry needs a card that matches the real trip.

Filling in the form

Have three things open beside you: your passport, your flight or crossing details, and your first night's booking confirmation. Then work through the sections:

• Identity: name and passport details exactly as printed in the passport - one wrong character is the most common cause of hold-ups.
• Travel: flight number or border crossing and arrival date, matching your booking.
• Stay: the address of your first night and a contact number or email.
• Health: a short set of standard questions.

Submit, and the system emails your card with a QR code - the proof immigration reads at the counter. Keep it on your phone, with a screenshot or print as backup. The portal can also scan your passport's MRZ to auto-fill fields, and a group submission covers up to 10 travellers at once. For a field-by-field version, see the form walkthrough.

At the immigration counter

A filed card does not grant entry - that decision belongs to the immigration officer. What it does is make the counter faster: your details are already in the system, matching your passport, instead of being typed in from a paper form while you wait.

The officer may also check things the card never covers: passport validity (six months beyond arrival is the safe standard), an onward ticket, proof you can support yourself, and the first-night address on your booking. Most travellers pass in minutes when these are in order.

Airside transit - staying inside the airport and flying straight on - needs no card at all. The moment you clear immigration, including to change airports in Bangkok, you are entering Thailand and the card applies.

Before you go: the short version

• Everyone entering Thailand files a card - children and visa holders included.
• File in the 72 hours before arrival, free, on the official portal.
• Match every character to your passport and booking.
• Details changed? Use the portal's update function - name, nationality and date of birth cannot be changed.
• Keep the email confirmation on your phone.
• Re-entering Thailand later? A fresh card for every entry.
