Only very few, but you are not supposed to be able to opening a bankaccount.
Reconsider if a Thai bankaccount is need-to-have or nice-to-have.
Banks in Thailand are like everywhere in the world, interested in having good stable custormers, that have a permanent address, a steady easy traceable income, and use the account all year round.
That is why the banks are reluctant to give accounts to people on short time ( read: tourist ) visas, and who only spend part of the year in Thailand.
Don’t expect to get a residence certificat, until you have stayed at a permanent adress in at least 3 month, since that is what the residence certificat should confirm.
Furthermore the added attention on whitewashing of money, is an added burden on the banks, so even depositing large amounts isn’t a guaranteed way to open an account.
The value of a resident certificat, had gone down, since Immigration Officers are giving them to people that are not on a longterm visa, or have stayed severel months at 1 adress in Thailand, so even if it is a formal requirement, the bank make up their own assesment of the stability of the want-to-be customer.
START BY READING THE WEBSITE OF THE DESIRED EMBASSY.
Most of the Embassies emphasize very strongly that if you make a error in the application, then the application will be rejected, and the Embassy staff can’t correct that.
(se example below)
Always, when asked for passport information, use the exact writing as in the machinreadable field, at the bottom of the picturepage.
