Arriving at Bangkok's Suvarnabhumi Airport (BKK) this high season? More foreign passport holders can now use the automated immigration gates instead of a staffed counter. But there are conditions, the rollout is happening in phases, and the Thailand Digital Arrival Card (TDAC) now plays a direct part in who gets sent to a gate. Here is what has changed, who qualifies, and how to plan your arrival.
Reviewed against Immigration Bureau TDAC guidance and published reports as of 22 October 2026.
What changed
Until recently, the automated arrival gates (Automatic Border Control, or ABC) at Suvarnabhumi were limited to Thai nationals plus Singapore and Hong Kong passport holders. In August 2026, ministers and immigration officials met at the airport to tackle long arrival queues. Immigration Division 2 said it planned to open the inbound auto gates to 33 nationalities. It said those nationalities were chosen using the Henley Passport Index, low entry-refusal rates and low security risk, and that the expansion was expected to start by this high season.
By late September, reports confirmed the expansion: 31 more nationalities and territories were added, for 33 in total. In early October, the Immigration Bureau again confirmed that the extra 31 nationalities had been approved to use the automated channels. It said the goal was to increase processing capacity and reduce waiting times for arriving passengers.
Who can use the BKK arrival auto gates
According to the published list, the 33 eligible nationalities and territories are:
Australia, Austria, Belgium, Canada, Czech Republic, Denmark, Finland, France, Germany, Greece, Hong Kong, Hungary, Ireland, Italy, Japan, Latvia, Luxembourg, Malaysia, Malta, Netherlands, New Zealand, Norway, Poland, Portugal, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, United Arab Emirates and the United Kingdom.
Passports from the United States, China, Taiwan and India are not included for now. Holders of those passports should expect to use the regular staffed immigration queue.
The conditions that matter
An eligible passport does not by itself get you through a gate. Three conditions stand out in the reporting:
- You must complete the TDAC before arrival. No TDAC, no gate.
- First-time visitors still go to a staffed counter. An officer collects your biometric data there, so your first entry is handled by a person.
- The rollout is phased. Holding an eligible passport does not guarantee that every traveller can use an auto gate straight away.
Even at a gate, immigration rules still apply in full. Officials have stressed that screening stays strict, and travellers who need a closer check are still sent to an officer.
The TDAC update: your email now shows your channel
On 15 October 2026 the Immigration Bureau released TDAC version 2026.10.00. According to the official release notes, the update:
- adds a step that checks and records whether you are eligible to use the automated passport control channel;
- shows that decision in the TDAC confirmation email;
- supports a "QR Code with Checkmark" in the QR code section of the email;
- sends the eligibility result to the Immigration Bureau's THIM app.
In practice, read your TDAC email carefully after you submit. It is meant to tell you whether you are expected to use an auto gate or a staffed counter. Keep the email and QR code easy to reach on your phone.
TDAC basics (unchanged)
The core TDAC rules have not changed:
- Submit within 3 days before arrival, including the arrival date.
- Every non-Thai national must submit one, including infants and children.
- A TDAC is valid for one entry only, so submit a new one each time you enter Thailand.
- Up to 10 travellers can be included in one family or group submission.
- You can update most details before entry. Your full name, passport number, nationality and date of birth cannot be edited. If one of those is wrong, submit a new form; the latest valid submission is the one that counts.
- Kiosks are available at five airports: Suvarnabhumi, Don Mueang, Phuket, Chiang Mai and Hat Yai. The Immigration Bureau says kiosks and Wi-Fi are provided on arrival for travellers without a smartphone or internet access.
The official TDAC is free at tdac.immigration.go.th. In August, ministers said they had found tourists being tricked by fake websites that charge fees. Check the address before you enter your passport details.
How busy is BKK immigration?
Figures given at the August meeting help explain why the gates matter:
- In low season, Suvarnabhumi handles an average of 70,000–75,000 inbound passengers a day.
- In the peak hours of 14:00–17:00, 5,000–6,000 people an hour reach immigration.
- In high season, daily arrivals may rise to 85,000–100,000.
- An auto gate takes on average 24–30 seconds per person when there are no security issues.
- Once the system is fully running, officials estimated that about 50% of inbound passengers could use the automated lanes.
Officials also said all immigration counters would be fully staffed at peak times. They described medium-term plans to study using the Satellite Terminal as an extra immigration checkpoint, and a longer-term push to speed up the East Terminal project.
What about Phuket?
Do not assume that every airport moved at the same pace. In mid-September, Phuket Airport Immigration denied reports that its arrival auto gates would open to 33 nationalities on 17 September. It said only three machines were working, and only for travellers from Thailand, Singapore and Hong Kong. It added that a wider rollout needs official regulations and a Royal Gazette announcement first, and that no opening date had been confirmed. If you are flying into Phuket, plan for the staffed counter unless an official update says otherwise.
Planning your arrival
If you are not eligible for the gates, or this is your first visit, give yourself extra time, especially if you land in the afternoon peak. Some travellers with young children, mobility needs or a tight onward connection choose a paid airport meet-and-assist or fast-track service. Check exactly what is included, because every passenger still has to clear immigration.
It also helps to have mobile data working before you land, for example an eSIM set up at home. Then you can open your TDAC email and QR code and book a ride without looking for airport Wi-Fi.
Arrival checklist
- Check whether your passport is on the 33-nationality list.
- Submit your TDAC on the official site within 3 days before arrival, including arrival day.
- Read the TDAC email to see whether you are directed to an auto gate or a counter.
- First visit? Plan to use a staffed counter for biometric collection.
- Keep your passport, TDAC QR code, onward ticket and accommodation details ready.
- Allow extra time if you land between 14:00 and 17:00.
- Phuket or another airport? Do not assume the BKK gate rules apply there.
