What happens if I don’t do the TDAC as China is very restricted with some websites ?
Answer summary
The TDAC (Thailand Declaration and Arrival Card) must be completed to enter Thailand, and travelers from China express concerns over website accessibility due to the Great Firewall. Users can fill out the TDAC at the airport using kiosks provided before immigration, or they can submit it online from outside China (e.g., during layovers). Many recommend having a VPN handy, which can help bypass restrictions if needed. Completing the TDAC is crucial for smooth entry into Thailand, and various options exist for registration to accommodate travelers.

It's easy and fast, you can fill out the form while walkalating from your arrival gate to immigration.

The queues to do DTAC at Suvarnabhumi on Wednesday were almost as big as immigration, it will certainly save you time to do it before you arrive.

Just came back from china. The great firewall is really only targeting google stuff and reddit. It isn't going to block Thai government websites

It blocks a lot of websites or slows them down considerably. The Bangkok Post website for example is not accessible in China.

The simple answer is you don't get in, but there are computers near the immigration section you can use to do it, 😉

I have a AIS roaming SIM and no problem doing it in Shanghai. I presume not many Chinese use VPN in China and they have no issues entertaining Thailand.

you can file a TDAC in the arrival hall of the airport before you go to stamp in. At Don Mueang and Suvarnabhumi they have kiosks (dunno about the other international airports)

Can you confirm that the TDAC website is blocked in China? I have been wondering about this.

I've just arrived on a flight from Shanghai. My fellow passengers, mostly Chinese, seemed to have no difficulty in entering at CNX, apart from some who appeared unaware of the DTAC requirement, but that's a separate issue.

You do it in the airport on your phone or on one of the provided TDAC terminals before immigration. However I very much doubt China has blocked the TDAC website.

Be aware that Google doesn't work in China, along with everything else you probably use on your phone at home. You have to use Bing to access the internet unfortunately.

You're right. Six weeks ago the Shanghai wifi wasn't working. This week was OK. No problem with VPN.

@Geoff ******
The WiFi at Shanghai was dogshit a few weeks ago, and my usual VPN didn't work because you can only use a few that the Chinese use.

@Dan *********
That's not true. I've just come from Shanghai to CNX. The WiFi at Shanghai Airport worked just fine and, with my VPN, I was able to access all my usual Internet connections.

that might be an issue with your phone or browser. Try clearing your cookies etc or a different browser. It could also even just be an issue with the website, they are notoriously known for not being very well made.

Regardless though, even on the very slim chance it is blocked, or there is an issue with the website, you have options Thai side, if worst comes to worst there are kiosks just before immigration you can do it on.
