Is a tax ID number mandatory for renting an Airbnb while applying for the STV visa in Thailand?

When applying for the STV (Special Tourist Visa) in Thailand, having a tax ID number from your Airbnb host is often required. This can be challenging if you are renting from a property owner who does not operate under a formal business structure, such as retirees who rent out their villas without a tax ID. Some users have successfully completed their STV applications with just a rental contract and the owner's passport, suggesting there may be flexibility depending on the situation.
