Administrative identification strings provide a unique numerical sequence for verifying the authenticity and registration status of a commercial seal in the People’s Republic of China. A 13-digit seal code is laser-etched onto the lower arc of the stamp face to ensure that every document signed by a corporation can be traced back to an authorized carving event. This sequence functions as a primary link between a physical object and the electronic records maintained by the provincial police departments.
It allows banks, government agencies and commercial partners to verify that a stamp is not a counterfeit or an unrecorded tool. The presence of these numbers indicates that the entity has completed the mandatory filing process required for legal existence and operation within the mainland jurisdiction. This system stops applying when a seal is formally destroyed and the registration is cancelled in the presence of administrative officers.
Geographic and organizational data points form the structural basis of the sequence to allow for rapid identification of a seal’s origin without immediate database access. The 13-digit seal code begins with a six-digit prefix that corresponds to the official administrative division code of the county or district where the company maintains its primary registration. These initial digits are followed by a four-digit block that identifies the specific engraving shop that was granted a special industry license to produce the stamp.
The final three digits serve as a serial number for the particular seal type, such as the official company chop or the financial seal, within that specific enterprise’s filing history. This arrangement ensures that no two seals in the entire country share the same identifier even if they belong to companies with similar names. By breaking down the code, an auditor can determine if a seal presented in a remote province matches the regional jurisdiction claimed by the contracting party.
Digital records maintained by the public security bureau receive an update every time a new seal is carved or an old one is replaced due to wear or loss. The 13-digit seal code is the primary key used to retrieve the high-resolution scan of the seal impression from the national management database. When a company applies for a new seal, the local police department generates this code and transmits it to the authorized carving shop through a secure network.
The shop then engraves the number onto the seal material, which is usually a hard polymer, copper or high-grade ox horn. Once the carving is complete, the shop submits a physical impression back to the police for final approval and archival. This closed-loop system prevents the circulation of unauthorized stamps that lack a corresponding entry in the government system.
Because the database is accessible to financial institutions, bank clerks can verify the seal on a check against the official record in real time.
Discrepancies between the engraved numbers and the official records indicate a high risk of fraud or a failure to comply with administrative filing requirements. A 13-digit seal code that does not appear in the provincial registry renders the associated document legally suspect and often unenforceable in a court of law. If the first six digits do not match the location of the business license, the seal is likely a counterfeit produced by an unlicensed workshop.
Many older seals produced before the current numbering standard remain in use but they lack the security features and the traceability of the modern system. Banks often require these older companies to upgrade their stamps to the new standard before allowing large-scale capital transfers or the opening of new accounts. If a seal is lost or stolen, the associated code is flagged in the system to prevent its further use in commercial transactions.
This invalidation process protects the corporation from the consequences of unauthorized signatures and ensures the integrity of the corporate identity.
PSB seal recordation binds corporate authority through a 13-digit code, overriding signatures unless fraudulent creation meets explicit civil code standards.
