TaeJing is a Thai website that brings together public information from government databases to help people check products, businesses, and organizations before making a purchase or payment. Users can search by product name, registration number, company name, or mobile device model and see whether a record is current, cancelled, or not found. The site covers Thai FDA registrations for food, medicines, cosmetics, medical devices, and other regulated products; NBTC approvals for phones and wireless equipment; TISI standards; halal and agricultural quality marks; and company registrations and tourism licences.

It also provides searches for local administrative bodies, schools, hospitals, temples, and businesses by province. TaeJing says its database includes millions of records from agencies such as the FDA, NBTC, TISI, the Department of Business Development, and the Department of Tourism, with automatic daily updates. The service is free to use and is intended as a reference tool, not an official government service.

TaeJing advises users to confirm information with the relevant source agency before making decisions
