Public Security Bureau Registration Rules for Chinese Corporate Seals
PSB seal recordation binds corporate authority through a 13-digit code, overriding signatures unless fraudulent creation meets explicit civil code standards.
Administrative procedure enables a company to register a new official chop with the Public Security Bureau when the original instrument is lost, stolen or destroyed. This emergency seal replacement filing is a critical recovery step because a company cannot sign contracts or complete government applications without its official seal. The process involves deactivating the old seal in the police database to prevent unauthorized use and authorizing the carving of a new one.
It applies to all registered legal entities in China, including foreign invested enterprises. The boundary of the procedure is the issuance of a new, legally recognized seal that bears a unique identification number. The law requires a specific sequence of notifications to ensure that the replacement is legitimate and that the public is protected from fraud.
Formal steps must be followed in a specific order to successfully register a new corporate chop. The emergency seal replacement filing begins with a report to the local police station where the loss occurred. The company must then publish a notice in a recognized newspaper to declare the old seal invalid.
This public announcement serves to warn potential counterparties that the old impression no longer carries any legal weight. After the notice has appeared, the legal representative must visit the Public Security Bureau with the company’s business license and their own identification. They submit a formal application for a replacement, explaining the circumstances of the loss.
The bureau then issues a permit that allows the company to visit a licensed seal carver. This sequence ensures that the new seal is created under government supervision and is not a counterfeit.
Updating the central database is the most important part of the replacement process for long term security. During the emergency seal replacement filing, the Public Security Bureau records the details of the new seal, including its physical characteristics and the date of issue. This record is linked to the company’s unified social credit code.
Any future verification of the seal by a bank or a government agency will refer back to this updated entry. The old seal’s record is marked as cancelled, which provides a clear audit trail in case of a dispute. If an unauthorized person tries to use the old seal to sign a loan agreement, the bank will see that it is no longer valid.
This digital record is the definitive source of truth for corporate authority in the Chinese administrative system. It protects the company from the consequences of the lost instrument and restores its ability to conduct business.
Recovery of the physical ability to execute legal documents allows the company to return to normal activities. Once the emergency seal replacement filing is complete and the new chop is in hand, the company must notify its key partners and financial institutions. The bank requires a fresh specimen of the seal to update the signature cards for all accounts.
Without this update, the company would be unable to transfer funds or pay its suppliers. Contracts that were pending signature can finally be executed, and mandatory government filings can be submitted. The company should also take this opportunity to review its internal seal management policies to prevent a recurrence of the loss.
This might include using a digital log or a secure safe with restricted access. The replacement process is a reminder of the physical nature of corporate power in China. It is a necessary disruption that ensures the integrity of the company’s legal representation.
Final success is measured by the seamless transition to the new seal across all operational and administrative channels.
