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.
13 Digit Security Code
Meaning
Identification numbers assigned to commercial certificates of registration by local administrative authorities establish the baseline authenticity of corporate documents. The 13 digit security code links physical certificates with electronic databases maintained by the State Administration for Market Regulation. This alphanumeric sequence sits on the upper right margin of the official document, acting as the primary reference for external audits.
Verification Mechanism
Online lookup portals hosted by regional government departments allow inspectors to validate the registry status of a company. Inputting the 13 digit security code retrieves the corporate name, registered capital, and operating scope of the entity in question. Discrepancies between the retrieved registry profile and the physical document signal potential falsification.
System Architecture
Regional variations in administrative databases determine the generation and storage protocols of the numerical sequence. Each 13 digit security code combines a geographic prefecture code, an industry classification digit, and a sequential registration number. This structure allows compliance auditors to verify documents offline by parsing the constituent elements of the string.
Compliance Outcome
Foreign joint ventures must verify the registry details of their local suppliers before executing procurement agreements. Failing to match the 13 digit security code with current state records invalidates the contract under local administrative guidelines.
