Verifying Chinese Public Security Bureau Corporate Seal Registrations
Validating Chinese corporate seals requires cross-referencing the thirteen digit PSB filing code against provincial police databases before contract execution.
Provincial Seal Database
Meaning
Regional electronic repositories in China hold the official records of registered enterprise stamps to prevent administrative duplication and forgery. Each provincial seal database, maintained by local public security departments, stores high-resolution digital scans and registration certificates of corporate stamps. This digital system serves municipal authorities and financial institutions within the specific province but does not automatically integrate with national business registries.
Verification Protocol
Checking the authenticity of a corporate stamp requires administrative queries through the designated system. When a bank opens a corporate account, officers run the stamp against the provincial seal database to confirm its active status. This verification ensures the stamp has not been revoked or superseded.
Bureaucratic Integration
Data sharing remains limited by regional administrative borders, meaning that a stamp registered in one province must be verified through that specific province’s system rather than a national portal.
Compliance Duty
Foreign purchasers operating in mainland China check the registered status of their suppliers through these networks before signing long-term supply agreements. Accessing the provincial seal database helps confirm that the supplier’s representative has the authorized stamp of the entity. Failure to verify this status can leave a buyer without legal recourse if the counterparty claims their stamp was a fake.
