Quarantine requirement at government designated site. From 1 May, if you’re fully vaccinated, you can apply to enter Thailand via Thailand Pass and do not need to quarantine. RT-PCR tests before and upon arrival are not required. You must have been fully vaccinated for at least 14 days before your date of travel and the vaccines must be approved by Ministry of Public Health.
If you are not fully vaccinated, you can enter Thailand under the Alternative Quarantine scheme or you can be exempted from quarantine if you have a COVID-19 RT-PCR test result issued no more than 72 hours before departure. You must quarantine at a State Quarantine or Alternative State Quarantine (ASQ) facility. You may be required to download the Thai Chana COVID-19 tracking app when you arrive.
