Source: TAT News (tatnews.org) — Thailand Immigration Management application introduced to streamline foreign traveller registration, 11 June 2026.
Thailand's Immigration Bureau has opened pilot access to THIM — the Thailand Immigration Management app — a traveller-facing mobile platform that lets foreign nationals complete their arrival registration from their phone, with the official launch expected in August 2026. It is your clients who install it, not the hotel. Crucially, it does not replace the Thailand Digital Arrival Card, and during the pilot it is optional: travellers may use THIM to access TDAC-linked registration, or carry on completing the TDAC through the existing official channel exactly as before. This briefing from a Thailand DMC for travel agents sets out what THIM is, what it is not, and what to tell clients arriving this season.
Explera is an IATA TIDS-registered ground handler trusted by 340+ agency partners, with in-house transport, licensed guides, 24/7 support and IATA TIDS registration (96215733). Reach the trade desk at b2b@explera.co.th.
What is the THIM app?
THIM stands for Thailand Immigration Management. It is a smartphone app published by Thailand's Immigration Bureau for foreign nationals, and the Tourism Authority of Thailand announced pilot access on 11 June 2026. Its headline convenience is passport capture: the traveller photographs the passport page and the app reads and saves the details automatically, so the arrival registration does not have to be typed out by hand. It is available on the iOS App Store and Google Play, and launched supporting English, Russian, Japanese and Chinese, with further languages planned. The Immigration Bureau's stated ambition is broader than arrivals — a single platform covering short-stay visitors, long-stay residents and other foreign nationals in Thailand.
Does THIM replace the Thailand Digital Arrival Card?
No, and this is the point to get right when briefing clients. The TDAC remains the mandatory pre-arrival declaration for foreign nationals entering Thailand by air, land or sea, and THIM does not remove that obligation or add a second one. What THIM offers during the pilot is an alternative, more convenient way to complete the same TDAC-linked registration from a phone. A client who has already submitted their TDAC through the official channel has done what is required; a client who prefers the app can use it instead. Neither route is a substitute for holding the correct visa or visa exemption for their nationality — that is a separate question, and one we cover in our visa rules by nationality guide alongside the mechanics in our TDAC guide.
THIM is not the hotel's TM30 filing
It is easy to conflate the two, so keep them separate in your own notes and in client briefings. TM30 is the accommodation-side obligation: under Thai law the property hosting a foreign national notifies immigration of that guest, and hotels and serviced apartments handle it as part of check-in. THIM is the traveller-side app. Your clients do not file a TM30, and their hotel does not complete their arrival registration for them. If a client asks why they are being asked for passport details at check-in, that is the property meeting its own TM30 duty — nothing to do with the app on their phone.
What agents should actually do before August
Four practical points. First, keep telling every client that the TDAC is required and to complete it in the days before travel — that advice does not change. Second, mention THIM as an option rather than an instruction while it is in pilot, so nobody believes their trip depends on installing an app. Third, watch for the official launch expected in August 2026 and re-read the Immigration Bureau's wording then, because features still under development — digital document submission, appointments with officers, online handling of selected requests — are exactly the sort of thing that gets announced with conditions attached. Fourth, do not promise capability that has not been confirmed; the safest line to a client is that Thailand is moving arrival formalities onto a phone app and the current requirement is unchanged.
How a Thailand DMC keeps arrivals clean
Entry formalities are where a smooth itinerary goes wrong before it has started, which is why they sit with the ground team. Explera tracks the Immigration Bureau's announcements as they land, keeps our pre-arrival client briefings current, and makes sure the meet-and-greet, airport transfers and guides are working from the same information your client received from you. That coordination is part of the wider Thailand DMC services for travel agents we run, tuned to the expectations of your source market — the documentation habits of a Gulf family group and a European FIT are not the same.

Selling notes for the trade
- TDAC still rules — the mandatory pre-arrival declaration is unchanged; say so in every pre-travel email.
- THIM is the traveller's app — your client installs it, not the hotel; it is optional during the pilot.
- Keep TM30 separate — that is the property's filing obligation and never the client's job.
- Diarise August — the official launch is expected then; re-check the wording before changing client advice.
- Promise nothing unconfirmed — future features are still in development and subject to the Bureau's confirmation.
Frequently asked questions
Do my clients need to download the THIM app?
Not during the pilot. THIM is a traveller-facing app, so it is your client — not the hotel — who would install it, but it is optional at this stage. What every client must still do is complete the Thailand Digital Arrival Card before arriving. Treat THIM as a convenience worth mentioning, not a requirement to enforce.
Does THIM replace the TDAC?
No. The Immigration Bureau and TAT have both been explicit that THIM is not an additional arrival-card requirement and does not replace the TDAC. It offers a phone-based route to the same TDAC-linked registration, with passport scanning to save typing.
When does THIM become mandatory?
Pilot access opened in June 2026 and the official launch is expected in August 2026. Exactly what becomes required at launch, and for whom, is for the Immigration Bureau to confirm — so re-read the announcement at the time rather than assuming the pilot behaviour carries over.
Is THIM the same as the hotel's TM30 registration?
No. TM30 is the accommodation provider's obligation to notify immigration about a foreign guest, handled by the hotel at check-in. THIM is the traveller's own app for arrival registration. The two are separate systems and neither removes the other.
What languages does the app support?
It launched with English, Russian, Japanese and Chinese, and the Immigration Bureau has said further languages will follow. For clients outside those languages, the existing official TDAC channel remains available, so nobody is blocked by the app's current language coverage.
