The Social Security Office holds the board election on Sunday 11 October 2026, 08.00-16.00. Employers and insured persons can check their polling station via SSO Plus, the sso.go.th site, or the SSO Line Official rich menu. Individual employers need an ID (ID card, driving licence, government card, or ThaID / DLT QR Licence app). A company employer must bring a company registration certificate dated within 6 months (or a DBD e-Certificate). If the company has two or more authorised signatories, one must be appointed in writing to vote for the company, and that person can vote for only one company. Employer ballots are blue; insured-person ballots are pink.
