Singapore passport holders remain eligible for visa-free tourist entry of up to 60 days in Thailand, but must also submit a Thailand Digital Arrival Card online within three days before arrival, according to Singapore’s Ministry of Foreign Affairs, checked 29 August 2026.
The MFA Thailand page, dated 9 December 2025 and re-checked on 29 August 2026, states that Singaporeans visiting as tourists are granted visa-free entry for up to 60 days under the Tourist Visa Exemption Scheme (TVES). From 1 May 2025, the same page says all non-Thai nationals must submit the Thailand Digital Arrival Card at tdac.immigration.go.th within three days prior to arrival. MFA says an acknowledgement e-mail is issued on successful submission and should be presented to the immigration officer at the counter.
Thai Immigration’s English user guide, checked 29 August 2026, states that the Thailand Digital Arrival Card is not a visa. The card is an online form that replaces the paper arrival card for travellers entering by land, air or sea. It does not replace TVES, a long-stay visa issued through the Royal Thai Embassy in Singapore, or the immigration officer who still decides entry. The TAT Newsroom notice of 4 April 2025 confirmed the same 1 May 2025 launch, describing the card as the electronic replacement for the paper TM.6 form.
Non-Thai nationals must file before entry
The Immigration Bureau applies the rule by nationality, not by airline. All non-Thai nationals entering the Kingdom of Thailand must complete the card online before entry. The official Immigration Bureau FAQ, checked 29 August 2026, says infants and children also need a TDAC. Group submission can include up to 10 entries. A family member, tour operator or authorised agent may complete the form for others in the party. Thai nationals do not file it.
Transit is the other exception. The FAQ says a TDAC is not required if a traveller is not passing through immigration. Technical landings and transit flights that stay airside do not need one. Leaving the airport, including a self-transfer that collects a bag and walks landside, is an entry. Crew are not required to submit, according to the same FAQ. Other visitors landing from Singapore remain required to file.
The acknowledgement e-mail sits with other arrival documents, including the Suvarnabhumi e-gate checks for Singapore passports. A ticket into Don Mueang rather than Suvarnabhumi still needs the Don Mueang terminal and document plan, because a connection can still clear immigration.
The Immigration Bureau directs travellers to file only at https://tdac.immigration.go.th. The English user guide sits at https://tdac.immigration.go.th/manual/en/. All details must be entered in English. The form requires passport information, personal information, travel information, accommodation in Thailand, a health declaration, and an e-mail address for the card to be returned. The FAQ states that a half-finished draft cannot be saved, so passport data and the hotel address need to be ready before Arrival Card is selected.
Filing window and locked fields
The window is three days in advance of the arrival date, including the date of arrival. The FAQ also states that the form can be submitted up to 72 hours before entry, and that the card is valid from the time it is submitted until arrival in Thailand. It is one-time: a new TDAC is required every time a traveller enters, on the expected date of arrival indicated. Printing is not required. The document with the QR code can be downloaded after submitting, or from the e-mail, and shown on a phone. A printed copy is only needed if no device will be available.
Submitted information can be updated before travel through Update Arrival Card, using the TDAC number, date of birth and nationality. Full name as it appears in the passport, nationality or citizenship, and date of birth cannot be updated. The FAQ adds passport number to that locked list. If those fields are wrong, a new form must be submitted. The system treats the most recent submission as valid. The card is compatible with visa-exempt entry and with other visa types, including visa-on-arrival. It remains a form, not permission to enter.
Kiosks are installed at five airports: Suvarnabhumi, Don Mueang, Phuket, Chiang Mai and Hat Yai. The Immigration Bureau presents a kiosk as a fallback if the website cannot be completed before landing. MFA still requires the acknowledgement e-mail at the immigration counter. If the website is unavailable, the FAQ recommends keeping a record of the error message and contacting airport or immigration staff. Passengers may be denied entry based on immigration discretion if the information is wrong.
The Singapore-side check remains MFA. The Thailand advisory also points long-stay visa applications to the Royal Thai Embassy in Singapore, and encourages e-registration at eregister.mfa.gov.sg so MFA can reach Singaporeans if needed. For the flight home, the Suvarnabhumi 100ml liquids rule for 2026 flights is a different control: cabin liquids, not entry. Thailand proof of funds for Singapore travellers is another entry check, not a substitute for TDAC.
The arrival card does not change the 60-day TVES line MFA still publishes. The remaining checks are whether TVES still covers the stay, whether the TDAC was filed inside the three-day window, and whether the passport details on the form match the passport presented at the counter.
Checked 29 August 2026 against MFA’s Thailand page and the Immigration Bureau TDAC manual and FAQ.
