FAQs for Thailand’s Blue Zone Sandbox Scheme

Thailand Pass

What is the Thailand Pass and where do I get it?

Thailand Pass is a digital platform aimed at streamlining the entry process for Thailand. From 1 November 2021, Thailand Pass replaces the Certificate of Entry (CoE). Once registered in the new system, travelers will receive a Thailand Pass QR Code to display to the airline and to screening officers at the immigration checkpoint. 

Here is everything about Thailand Pass

How long does it take to process Thailand Pass?

If you meet all the requirements, it should take between 3-5 working days to process your application, but travelers are advised to allow at least 7 working days.

Insurance and visas

Is Covid-19 insurance mandatory?

Yes. You need to have insurance for Covid-19 that covers medical costs up to a minimum of USD $20,000 for the entire duration of your stay in Thailand*. If you are travelling with children, they will also need to be covered by insurance.

Travelers should check the small print of any Covid-19 insurance policy before purchasing. The policy should cover:

  • The cost of treatment and other medical expenses associated with testing positive for Covid-19 or being designated as a high-risk contact (including in-patient hospitalization, hospital isolation, hotel isolation, or related quarantine).

You may want to know what is happening on the ground if your Covid test result returns positive

Do I need a visa?

Thailand is famous for its easy visa system for those travelling to Thailand as a tourist and staying for less than 30 days, you do not require a visa. Instead, you can enter under the visa exemption scheme. If you wish to stay longer, you can apply for a Tourist Visa which will allow you to stay for up to 60 days plus a one-time extension of 30 days if required.

Here is our guide for Thailand Visa

Covid vaccinations and tests

Can it be any Covid vaccine and what proof do I need to show?

The vaccine must be approved by the World Health Organization (WHO) or the Thai Food & Drug Administration (FDA). The FDA approved list includes AstraZeneca, Johnson & Johnson, Moderna, Pfizer, Sinopharm, and Sinovac. Visitors need to be fully vaccinated with two shots of the vaccine (one shot for Johnson & Johnson). Vaccination shots need to have been given at least 14 days before boarding your flight to Thailand and no longer than one year before.

If I’ve not been vaccinated or only received one dose of the AstraZeneca jab, can I still travel to Thailand?

You can, but you will need to follow the current entry procedures and enter quarantine on arrival. You can only visit without quarantine if you have been fully vaccinated with both doses of the jab (or one shot for the Johnson & Johnson vaccine).

Here is the Happy Quarantine entry scheme for not-fully vaccinated travelers

After I arrive in Thailand, how long will I have to wait before I get the first Covid-19 test result?

Results should be available within 8-12 hours.

Where will the first RT-PCR test take place and how much does it cost?

The first test will be carried out at the arrival airport, and you will need to book and pay for both your first test and second test in advance via the official website. The cost is 2,100 Baht per test

What apps do I need to download?

When you arrive in Thailand you will be asked to download the MorChana app as part of the Covid safety protocols:

What happens if I’m staying in Thailand less than 6 nights?

The self ATK test will not be required if your length of stay in a Sandbox destination is less than 6 nights or your international departure date out of Thailand is on Day 5 or before. If you are staying for 6 days (nights), you will be required to undergo self ATK test on Day 5-6.

Please note, you still need to follow the requirements of your airline and should check if another RT-PCR test is required for the international destination you are flying to.

This varies depending on your government’s policy. Check out with the local authorities where you live.
