From 1 November, platforms such as Facebook, Instagram, TikTok, YouTube and X must verify advertisers' identity before publishing paid ads in Thailand. Verification can use an ID document matched to the user (possibly via facial comparison) or a reliable digital ID system. Authenticated advertisers within the past year are exempt. If you run paid ads, prepare your national ID or juristic-person registration certificate, and keep ad records (advertiser, contact details, payer if different) for at least 90 days after each ad ends. Ads from unverified accounts may be blocked.
