Thailand's government will require all social media platforms (Facebook, Instagram, TikTok, YouTube, X, etc.) to verify advertiser identities before publishing ads starting Nov 1. The rule—published in the Royal Gazette on May 5—aims to prevent tech-related fraud and scams conducted through paid social media advertising. Platforms must verify identity through government-issued ID or reliable digital authentication; advertisers authenticated within one year are exempt. Data must be retained for at least 90 days after campaign end. This directly impacts SMEs and any business using paid social ads in Thailand.
