Is quarantine required for Indians traveling to Thailand under a tourist visa?

Tourists can enter Thailand with or without quarantine. Vaccinated travelers can bring a copy of their vaccination certificate on hand and there is no requirement for an RT-PCR test report. 

In case, if you’re unvaccinated, you must undergo an RT-PCR test through an approved clinic before entering Thailand. Make sure that test results must be issued within 72 hours before your travel.
