A black market passport dealer from Myanmar who was working in Bangkok explained to a reporter about the illegal passport trade in Thailand. According to the dealer, there are three types of passports that are available for sale on the black market: Stolen passports, real passports that the owner is selling in order to make money, and fake passports.
The price of passports in Thailand depends on the issuing country. A passport from Myanmar (Burma) costs between $1,300 to $2,000 (40,000 Thai Baht to 60,000 Baht). Black market passports from European Union countries are available for sale for $2,600 (80,000 baht). The most expensive passports in Thailand are from the United States, which sell for $3,300 (100,000 baht).
