Why choose Service eVisa?
While you can submit your declaration independently on the official government portal, no prior data review is offered there. Because identity fields cannot be edited once submitted, even a minor typo requires lodging an entirely new declaration. Here is why travelers choose our tailored support.

Thai entry regulations
What Is the Thailand Digital Arrival Card (TDAC)?
The TDAC is neither a visa nor an electronic travel authorisation: it is an entry declaration required for every foreign national passing through Thai immigration, regardless of status, whether traveling visa-exempt, on an eVisa, or holding a long-stay visa. It centralises your personal details, travel itinerary, accommodation address in Thailand, and an electronic health declaration.
You must submit your declaration within the 72 hours prior to your arrival. Applications filed earlier are automatically rejected by government servers. Once submitted, identity fields (name, passport number, date of birth) cannot be corrected; any entry typo requires filing a brand new declaration.
Good to know: The TDAC is a single-use declaration. A new form is required for every individual entry into Thailand, including same-day border crossings.
Who Needs to Submit the Thai Entry Declaration?
Unlike a visa, the TDAC applies universally: there is no country eligibility list to check against. Every foreign national clearing Thai border control must complete it on every entry.
Exempt travelers include passengers in pure international airside transit (without clearing immigration), Thai citizens, and holders of local border passes.
Short stays (tourism, business)
The TDAC is mandatory prior to arrival, whether you travel visa-exempt, on an eVisa, or on a long-stay visa.
Long stays or visa-required travel
If you plan to work, study, or settle in Thailand long-term, the TDAC remains an arrival declaration only and does not replace a required visa. The appropriate visa must be obtained prior to departure.
How Long Can I Stay in Thailand Without a Visa?
Nationals of eligible countries can enter Thailand visa-free for stays of up to 60 days. This permitted stay can be extended once for an additional 30 days upon application at a local immigration office.
Note: The Thai government has approved a framework to adjust this visa-free duration to 30 days for most eligible nationalities. As implementation dates depend on official publication, the granted length of stay strictly reflects the regulations in force at the exact time of your entry. You may verify current rules on the official Immigration Bureau portal or via a Royal Thai Embassy. Visa-exempt entry covers leisure and tourism exclusively: engaging in any paid employment is strictly prohibited.
What Happens at Arrival Checks in Thailand?
At major international airports such as Suvarnabhumi and Don Mueang, automated gates (e-Gates) cross-check your TDAC data against your passport chip and live facial recognition. Any data discrepancy—such as a typo in your name or passport number—will lock the gate and redirect you to a manual inspection counter.
Thai immigration officers retain full authority to inspect supporting documentation upon arrival. We recommend keeping your QR code, confirmed return or onward ticket, proof of accommodation, and evidence of sufficient financial funds readily accessible.
Good to know: The TDAC is an entry declaration; it does not guarantee admission. Final entry permission and granted stay duration are determined by the immigration officer at the port of entry.
Health, Insurance, and Customs: What You Need to Know
Foreign visitors are not covered by Thailand's public healthcare system. Because any medical care must be self-funded, purchasing comprehensive travel and health insurance prior to departure is strongly recommended. A Yellow Fever Vaccination Certificate is mandatory for travelers arriving from or transiting through endemic risk regions.
Regarding border customs, e-cigarettes and vaping devices are illegal and strictly prohibited in Thailand. Foreign currency exceeding permitted thresholds must be declared upon arrival, and Thai law enforces severe legal penalties for drug-related offences.
Data Protection, Security, and Checks
Every application submitted through Service eVisa undergoes thorough verification before being sent to Thai immigration authorities. Our system automatically detects formatting errors, transposed passport numbers, and inconsistent data, eliminating the primary causes of processing delays.
Your personal information is protected with end-to-end encryption, and payment details are deleted immediately after transaction confirmation.
Frequently Asked Questions — Thailand TDAC
Yes. Traveling without proof of onward travel frequently causes issues. Thai immigration officers and airlines routinely require proof of a return or onward ticket (to a third country) within your permitted stay duration. Lacking onward proof is a leading cause of denied boarding or entry. If your dates are flexible, secure a changeable return ticket or a confirmed onward booking to a neighboring country.
Simply enter the address of your initial accommodation (your first night or initial stay upon arrival). You do not need to have booked every night of your stay for your TDAC to be valid.
No. To legally drive in Thailand (whether a motor scooter or a car), you must hold an International Driving Permit (IDP) alongside your national driver's license. Operating a vehicle without an IDP leads to immediate fines at police checkpoints and, critically, invalidates insurance coverage in the event of an accident.
Yes, the Destination Thailand Visa (DTV). This visa is specifically designed for remote workers, freelancers, and digital nomads. Valid for 5 years with multiple entries, it permits stays of up to 180 days per entry, extendable once locally. Note: the DTV must be obtained prior to departure via the official Thai eVisa portal; it does not replace the TDAC entry declaration, which remains mandatory on every arrival.
