Thailand’s Electronic Transactions Commission published a notification in 2026 requiring online social media service providers to verify the identity of advertisers before ads are published, in response to a rise in fraudulent ad accounts. Verification relies on identity documents or an approved digital identity system and has to be renewed periodically, and providers must keep advertiser details for a period after the relationship ends. Because the notification targets social media services, whether and how it applies to Google Search ads needs confirming close to launch rather than assuming either way.
The notification also reaches third parties that pay for ads on an advertiser’s behalf. If an agency pays for a client’s ads, the platform must verify and keep records on that agency as well, so billing arrangements in Thailand need to be settled with this in mind. Identity documents collected for verification are personal data too, which adds to the PDPA obligations that already apply to conversion tracking and remarketing, including the rules on transfers abroad.
Campaign quality still depends on language. Thai ad copy has to be written for Thai search wording, and character limits, the landing-page experience and the ad text need to be reviewed together, because copy translated from a home-market campaign tends to read unnaturally and miss local buyer terms. An English-language audience, where there is one, is set up as a separate campaign.
