Landing in Thailand: Immigration, Customs, Cash and Getting into Bangkok (2026)

This page covers the hour after you land at Suvarnabhumi (BKK): immigration, baggage, customs, then the arrivals hall. Every limit below links to the government or airport page it comes from, with the date we last read that page.

The TDAC itself is covered in the TDAC overview and the field-by-field guide. File it within 3 days before arrival. It is free.

The order after you land

1. Immigration. Passport, plus the TDAC you filed. Most foreign visitors use a staffed counter.
2. Baggage claim.
3. Customs. Green channel if you have nothing to declare, red channel if you do.
4. Arrivals hall. SIM or eSIM, money, then transport into the city.

Immigration: counter or automated gate

The staffed counter is the default for foreign visitors.

Some passports can use the automated e-Channel instead. The Thai consulate-general in Hong Kong says Hong Kong SAR passport holders can use it at Suvarnabhumi when both conditions hold (source, page dated 2026-02-25):

• you enter under a visa exemption, and
• your current passport was used to enter Thailand before and has an entry stamp from that visit.

First-time visitors on that passport go to the counter.

In August 2026 the Thai government said the gates would open to more nationalities at Suvarnabhumi, in phases. We have not found the final list on an Immigration Bureau page, so we do not repeat the lists that travel sites publish. If the gate rejects your passport, the counter is right there.

Customs: what you can bring without duty

From Thai Customs’ page for arriving passengers (source, checked 2026-09-12):

• Use the green channel only when you carry nothing dutiable, prohibited or restricted.
• Excess tobacco or alcohol must go in the Customs disposal box. Thai Customs warns that skipping this can lead to prosecution.
• Non-commercial accompanying goods worth up to THB 200,000 are assessed at the red channel.
• Declaring a prohibited or restricted item does not make it legal to bring in.

Cash: when you must declare

From the Bank of Thailand’s exchange control page (source, checked 2026-10-14):

• Declare to Customs if you carry baht banknotes over THB 450,000, or foreign currency banknotes over USD 15,000 or its equivalent. This applies on entry and on exit.
• Coming in: no upper limit on baht or foreign banknotes. The threshold is about declaring, not a cap.
• Going out: foreign banknotes up to the amount you bought from authorised banks or money changers. Baht up to THB 50,000 for most destinations, or up to THB 2 million to countries bordering Thailand, Vietnam, and China’s Yunnan province only.

Getting from Suvarnabhumi into Bangkok

Public taxi. From Airports of Thailand’s taxi page (source, checked 2026-10-14):

• The taxi counter and ticket machines are on Floor 1 of the passenger terminal, between Gate 4 and Gate 7.
• Drivers add a 50 baht airport charge, set by a Ministry of Transport announcement.
• Expressway tolls are paid by the passenger.
• A Short Distance service covers trips of no more than 20 km around the airport.
• The page lists baggage charges only as an image. Ask at the counter before you get in.

Take a ticket from the official counter or machine. Drivers who approach you inside the terminal are not part of that queue.

Public bus. From Airports of Thailand’s bus page (source, checked 2026-10-14):

• BMTA route S1 to Sanam Luang leaves from the passenger terminal, 06:00 to 17:00, 60 baht for the whole line.
• Two different services are numbered 555 and both leave from the Public Transportation Center: BMTA 555 to Rangsit (maximum 37 baht) and a public minibus 555 to Don Mueang (maximum 60 baht). Check the destination on the front of the bus.

Airport Rail Link. The train runs from the airport to Phaya Thai, where it meets the BTS Skytrain. Its operator changed in 2026 and we could not find a current official fare page, so we do not quote a fare. The station ticket machines show the price.

Getting online

If your phone supports eSIM, you can buy and install a data plan before you fly and switch it on after landing. Check the phone’s settings first: many phones sold in mainland China do not support eSIM.

A physical Thai SIM bought at the airport is registered to your passport at the shop, so keep the passport out after immigration.
