Do I need an address in Thailand to form a Thai company?

Yes, your company must be registered at a physical address in Thailand, and this is where you will receive official documents and notices. If you rent this address, you must first get permission from the property owner to agree to register your company at the location. You will need to keep the Ministry of Commerce updated should you move the place of your company registration. A commercial address may also be required, depending on the business you are operating.
