What to have ready

Have these in front of you for every traveller before you open the form. Copy names and numbers from the passport itself, not from memory. The form, field by field.

From each passport

  • A passport for each traveller, children and babies included
  • Family name and given names as the machine-readable zone writes them: the two lines of letters and chevrons at the bottom of the photo page. Middle names included
  • Passport number, checked character by character: 0 and O, 1 and I, 8 and B
  • Nationality, the country that issued the passport, and date of birth
  • Occupation: one short word is enough, such as Teacher, Retired or Student
  • Visa number, if you have a visa

About your trip

  • Arrival date: the day you land in Thailand, in Thai time. On an overnight flight it is often the day after you leave
  • Flight or vehicle number of your last leg into Thailand, as on your boarding pass
  • Purpose of your trip, such as holiday
  • Where you sleep the first night: accommodation type and name, province, district, sub-district and postal code, copied from your booking
  • Countries you were in during the last 14 days, including a layover where you passed through immigration
  • An email address you can open while travelling: your TDAC is sent there

When you can submit

First day

3 days before your arrival date

Last day

Your arrival day, before you reach immigration

Days you can submit

4 calendar days

The days count from your arrival date in Thailand, not from your departure. Find your dates with the calculator, or read when to submit your TDAC.

Who needs a TDAC

  • Every traveller who is not Thai, babies and children included: one TDAC per person
  • Arrivals by air, land or sea
  • Families and groups: one person can submit for up to 10 travellers at once, and each traveller gets their own TDAC and QR code

Who does not need one

  • Thai nationals
  • Transit passengers who do not pass through Thai immigration
  • Crew
  • Travellers who enter with a Border Pass

After you submit

  • Check every name, the passport number and the arrival date on the confirmation
  • Download the TDAC document with its QR code. A copy also goes to your email
  • Save it on your phone so you can show it without internet. A printed copy helps if you will not have a phone with you
  • Keep every traveller's QR code: each person has their own

If something changes

You can change details such as your flight or accommodation with Update Arrival Card on the official website. A wrong full name, passport number, nationality or date of birth cannot be changed: submit a new, correct TDAC instead. How to fix TDAC problems · The most common TDAC mistakes
