Does the rule apply to a platform operated outside Thailand?

Yes, if it serves users in Thailand (section 9). Section 10 lists signs such as Thai language, a .th domain, baht payment, Thai law or courts, or staff supporting Thai users.

Does Thai data protection law apply to an offshore platform?

Yes, where it offers goods or services to people in Thailand, paid or free, or monitors their behaviour in Thailand (PDPA section 5). It must generally appoint a representative in Thailand (section 37(5)).

Are payment platforms covered?

Platforms regulated by the Bank of Thailand or the SEC are excluded from the Royal Decree (section 4); their own rules apply instead.

Launching a Marketplace or Online Platform in Thailand: What to Assess

Published 6 Oct 2026

A digital platform serving users in Thailand can need to notify the Electronic Transactions Development Agency (ETDA) before operating, under the Royal Decree on Digital Platform Services that Require Notification B.E. 2565, once it passes set revenue or user thresholds. The Royal Decree also covers platforms operated from outside Thailand that serve Thai users. Separately, the Personal Data Protection Act B.E. 2562 reaches offshore controllers that offer services to people in Thailand. What applies depends on the model, the money flows and the users.

Thresholds and scope of the platform notification

Point	What the Royal Decree provides
What is a platform	An electronic intermediary connecting businesses, consumers or users for electronic transactions, paid or free; excludes a platform selling only one operator's or its group's own goods or services
Revenue threshold	More than THB 1.8 million a year from platform services in Thailand for an individual, or more than THB 50 million for a juristic person (section 8)
User threshold	More than 5,000 users in Thailand a month on average (section 8)
Offshore platforms	Must notify if they serve users in Thailand; signs include Thai language, a .th domain, baht payment, Thai law or courts, or Thai staff (sections 9 and 10)
Excluded	Platforms regulated by the Bank of Thailand or the SEC (section 4)

Four questions a platform launch has to answer

Is the service a platform intermediary, or a shop selling its own goods and services?
Will it pass the revenue or user thresholds, and is it operated from Thailand or abroad?
Who holds customer money, and could a payment or stored-value function bring in Bank of Thailand rules?
What personal data does it collect from people in Thailand, and if the controller is offshore, does it need a representative in Thailand?

Questions people ask

If it is a digital platform service within the Royal Decree B.E. 2565 and passes the revenue threshold (THB 1.8 million a year for an individual, THB 50 million for a juristic person) or the user threshold (more than 5,000 users in Thailand a month). Platforms below the thresholds give a shorter notification.
