If you have been reading travel forums recently, you might be panicking about a "Thailand ETA" (Electronic Travel Authorization). Some outdated blogs claim you need to pay a tourism tax or register months in advance. Here is the definitive answer on which digital form is actually mandatory for your 2026 trip.
Key Takeaways
- The standalone ETA proposal has been merged into the TDAC system.
- You only need one form: the Thailand Digital Arrival Card (TDAC).
- Scam sites still sell fake "Thailand ETAs" for $50–$100. Do not pay them.
- The TDAC is mandatory for ALL foreign arrivals, regardless of visa type.
The Short Answer
- Do you need an ETA? No. The standalone ETA proposal was effectively replaced by the mandatory TDAC system.
- Do you need a TDAC? YES. This is the single mandatory digital form for all foreign arrivals in 2026.
What Happened to the ETA?
The ETA was merged into the TDAC system and no longer exists as a separate document — if you see a site selling Thailand ETAs, it is a scam. The Electronic Travel Authorization was originally proposed as a separate pre-travel screening system, similar to the US ESTA or EU ETIAS.
However, to avoid redundancy and confusion at the border, the Thai government integrated these security checks into the Digital Arrival Card (TDAC) system under the Immigration Bureau.
The Result
You do not need to file two separate "permission to enter" forms. You only need to file the TDAC. One form, one QR code, one immigration scan.
ETA vs. TDAC: Side-by-Side Comparison
| Feature | ETA (Cancelled/Merged) | TDAC (Mandatory) |
|---|---|---|
| Purpose | Pre-travel security screening | Immigration & health declaration |
| Status | Inactive | Mandatory |
| Filing Time | Was proposed as "weeks before" | Recommended 72 hours before arrival |
| Cost | Was proposed as 300 THB | Free |
| Platform | Never fully launched | TDAC Portal (or our agency service) |
Why This Confusion Is Dangerous
Scam websites charge $50-100 for fake Thailand ETAs that have no legal value — you arrive thinking you are cleared, only to be sent to the TDAC kiosk at the airport. These scam websites still exist and actively target travelers searching for Thailand travel authorization.
- Risk: You pay for a document that does not exist.
- Consequence: You arrive at Bangkok Suvarnabhumi Airport without a TDAC, thinking your "ETA" covers you. You will be sent to the back of the immigration line to fill out the correct form on a crowded airport kiosk.
Scam Warning
If any website asks you to pay for a "Thailand ETA" or "Electronic Travel Authorization" separately from the TDAC, it is likely a scam. The only mandatory digital entry form for Thailand in 2026 is the TDAC.
How to Stay Safe
- Ignore "ETA" requirements unless explicitly told otherwise by a Thai Embassy for a specific diplomatic mission.
- Focus on the TDAC. This is the only barcode Immigration Officers want to see on your phone (or printed paper).
- File correctly. Ensure your TDAC matches your passport data exactly — the Machine Readable Zone (MRZ) at the bottom of your passport page is what the system validates against.
