Is Prostitution Legal in Thailand?

Thailand's Prevention and Suppression of Prostitution Act B.E. 2539 (1996) defines prostitution broadly, as sexual intercourse or other sexual acts done for money or any other benefit (Section 4), and penalises what happens around it. Soliciting in a street or public place in a way that is open and shameless or a public nuisance carries a fine of up to 1,000 baht (Section 5). Associating with others in a prostitution establishment for prostitution can mean up to a month in jail or a 1,000 baht fine (Section 6). Owners and managers of a prostitution business face three to fifteen years in prison (Section 11).

Change has been proposed. In May 2026 the Empower Foundation submitted a bill to repeal the 1996 Act and treat adult sex work as work (Khaosod English). On 10 July 2026 House leaders classed it as a money bill, which means it cannot be debated without Prime Minister Anutin Charnvirakul's endorsement (Thai Examiner). He had not endorsed it when sex workers petitioned him in August 2026 (Pattaya Mail).

Gogo bars, beer bars, karaoke and massage shops are ordinary licensed businesses, and the main nightlife strips of Bangkok, Pattaya and Phuket trade in the open. The legal line is the sex-for-money part and running a venue for it: the Act treats any place set up for prostitution, or used for soliciting it, as a prostitution establishment (Section 4). Ministry of Interior figures cited by sex-worker advocates count more than 10,000 registered entertainment venues (Thai Examiner).

Hours matter more day to day. Since 15 December 2023, licensed venues in tourist zones of Bangkok, Phuket, Chon Buri (which includes Pattaya), Chiang Mai and Koh Samui may stay open until 4 am (TAT). Since 29 May 2026 alcohol can be sold from 11 am to midnight with no afternoon gap, while licensed entertainment venues and hotels follow their own licence conditions (TAT).

The Act applies to everyone in Thailand. Its penalties fall mainly on soliciting, procuring and running venues, and the heaviest penalties a customer can face involve anyone under 18 (Section 8). For foreigners, the bigger risk is the visa. Immigration can revoke permission to stay, deport and blacklist people judged harmful to society, which is what happened to ten Vietnamese women fined 1,000 baht each for street soliciting in Bangkok, in a case reported in May 2026 (Pattaya Mail). Police still run periodic sweeps, such as one in Pattaya in August 2026 ahead of a US Navy port visit (Khaosod English).

Sex with anyone under 15 is a crime in Thailand whatever the circumstances, with prison terms of up to 20 years (Criminal Code Section 277, via UN Women). Where prostitution is involved the line is 18: sex with a person aged 15 to 18 in a prostitution establishment carries one to three years in prison and a 20,000 to 60,000 baht fine, and with a child under 15, two to six years and a 40,000 to 120,000 baht fine (Section 8 of the 1996 Act). Bars check ID for another reason too: the legal drinking age is 20 (TAT).

If you think someone is trafficked, forced to work or underage, the Ministry of Social Development and Human Security runs the 1300 hotline, and police have a dedicated anti-trafficking line on 1191. The Tourist Police on 1155 answer 24 hours a day and are often the easiest first call for visitors. The US State Department reports that Thai government hotlines have operators for 19 foreign languages (2025 Trafficking in Persons report).
