Verifying PRC Corporate Seal Authenticity and Public Security Filings
Verify PRC seals by matching the 13-digit PSB security code against municipal police databases and confirming official Beian filing certificates before signing.
Carving House License
Meaning
Special sector permits issued by the Public Security Bureau regulate the manufacturing and engraving of official corporate seals. A carving house license ensures that only authorized establishments can produce the stamps that legally bind companies to contracts and official declarations. This permit is tightly controlled to prevent the proliferation of unauthorized seal makers who might facilitate corporate fraud.
Sovereign Control
Regional public security bureaus inspect these licensed establishments regularly to verify that their equipment is registered. An holder of a carving house license must run specialized engraving machines that link directly to the police database. This link ensures that every manufactured corporate chop possesses unique digital markers that are recorded centrally.
Procurement Protocol
Companies seeking a new seal must first obtain an official approval letter from the local administration. They then present this letter to an establishment holding a carving house license to execute the physical engraving. This process ensures that the resulting corporate seal is legally recognized and registered for official transactions.
Security Risk
Acquiring seals from an unapproved vendor who lacks a carving house license renders the stamp illegitimate in court. Agreements stamped with such seals are often unenforceable, creating severe legal risks for the contracting parties.
