Passport and identity documents

Before booking a trip to Thailand, travellers should check that their passport meets the basic requirements:

  • The passport remains valid for at least six months from the date of arrival.
  • There is at least one blank page available for the immigration stamp.
  • The passport is in good physical condition, without significant damage.

Travellers with dual nationality should decide which passport they will use and use it consistently for the visa, TDAC and immigration checks.

Visa or permission to enter

Travellers should verify in advance which entry route applies to them:

  • Visa exemption for short stays, where the nationality is eligible.
  • Visa on arrival at specific checkpoints, where applicable.
  • A visa obtained in advance for longer stays or specific purposes.

The official Royal Thai Embassy or Consulate for the country of residence is the authoritative source for visa rules. Travellers should not rely on third-party summaries when planning.

Thailand Digital Arrival Card

The TDAC is part of the standard process for almost all foreign arrivals. Practical points include:

  • Submitting the form within the official window before arrival.
  • Matching all fields to the passport and booking documents.
  • Keeping the confirmation accessible at the border.

Tickets and proof of onward travel

Airlines and immigration officers may request evidence of onward travel, especially for travellers entering under visa exemption. Useful documents include:

  • A return or onward flight ticket.
  • Train, bus or ferry tickets out of Thailand for overland onward journeys.
  • A booked itinerary that clearly demonstrates the intention to leave within the permitted period.

Accommodation and itinerary

It is reasonable to be ready to describe where the trip will take place and where the traveller will stay, particularly on the first night. Travellers should:

  • Have at least the first accommodation booked.
  • Carry the booking confirmation, either printed or on the phone.
  • Be able to describe the planned itinerary briefly if asked.

Financial means

Thai regulations may require travellers to demonstrate sufficient funds for the stay. While checks are not systematic, travellers should be prepared:

  • Carry a payment card that works internationally.
  • Keep some cash in Thai baht or a major currency.
  • Avoid arriving with no visible means of support.

Health and insurance

Health requirements vary over time. As a general rule, travellers should:

  • Check current vaccination recommendations for Thailand.
  • Consider travel insurance that covers medical care and repatriation.
  • Bring sufficient supplies of prescription medication, with a copy of the prescription where relevant.

Customs and prohibited items

Travellers should familiarise themselves with Thai customs rules before packing. Particular attention should be paid to:

  • Limits on tobacco, alcohol and certain foodstuffs.
  • Restrictions on certain medications, including some over-the-counter drugs from other countries.
  • Prohibitions on illegal substances, which are treated extremely seriously.

Final checklist before departure

On the day before travel, a short final check helps ensure that nothing has been forgotten:

  • Passport, visa (where required) and TDAC confirmation are easy to reach.
  • Flight, accommodation and onward travel documents are accessible offline.
  • Phone is charged and has a payment method ready for local transport.
  • Emergency contacts and insurance details are written down or saved offline.
