Will BKK immigration check my insurance policy upon arrival if I have Thai Pass, and what is the validity period for such a pass?

The user's inquiry revolves around their upcoming trip from Bangkok to Kuala Lumpur and back, specifically regarding the Thai Pass and insurance requirements. They asked if BKK airport immigration would check for a COVID insurance policy upon arrival, and whether their general travel insurance would suffice. Additionally, they wanted clarification on the validity period of the Thai Pass and how the airport of arrival (DMK vs BKK) may affect their entry. Responses indicate that immigration typically does not check insurance policies if the Thai Pass is approved, and general international travel insurance is usually acceptable. The Thai Pass validity can vary, and users noted that airlines are more likely to scrutinize documents before departure.
