Make sure you don't get scammed like many have from searching TDAC on Google, as the first result is typically a sponsored website beginning with "iv" that charges over $100 USD for a TDAC. The real government TDAC website is free. tdac.immigration.go.th

Routing numbers are a US system for US transfers, just like IBAN is a European system. It isn't used in Thailand. For international transfers, you need the SWIFT code and the bank account number.

Your statement doesn't make sense. You only file a 90 day report for every 90 days that you have been in Thailand consecutively. If you leave the country before the next 90 day report is due, then you wouldn't file one from outside the country, which you mentioned as an option, as you haven't stayed 90 days consecutively since your last report.

@Dany *******

why do you assume people who live in Thailand full time, perhaps for decades, would have any significant assets or presence in another country? Most people only have bank accounts in the country they spend their life in.

@Nelly ********

tourist visas grant 60 days, same as a free visa exempt entry. You only get an additional 30 days by extending it at immigration offices within Thailand, whether on a tourist visa or visa exempt entry. You are likely confusing the 90 day validity period of a tourist visa, which means you must use it within 90 days of issuance, not that it grants a 90 day stay. You only get 60 days from whenever you choose to use it for a single entry within the 90 day validity period.

@Nelly ********

it's been 60 days + 30 day extension since almost a year ago. You don't need a tourist visa to stay 90 days. Tourist visas are also for 60 days and require the same 30 day extension so there's no point in getting one.

@Simon ******

every doctor, clinic and hospital in Thailand knows what a medical certificate is, as it is required for many Expat activities like work permits, drivers licenses, etc. Costs as low as 100 baht from clinics, or up to 900 baht or so at hospitals. Just walk in and ask for one.

Did you search "bank account"? This exact question is asked very frequently and there are already tons of answers to those posts that can guide you.

it shows on the computer screen for the immigration officer. They only need your screenshot or printout as a backup. Otherwise they won't ask for it.
