Thailand is divided into 75 provinces , which are gathered into 5 groups of provinces by location. There are also 2 special governed districts: the capital Bangkok and Pattaya. However Pattaya is still part of Chonburi Province. Some Thai people still count Bangkok as one province, making Thailand a 76-province country.All our thai web hosting accounts have spam filter, virus scanner and frontpage extensions preinstalled.
