Chinese ID Card, USCC and Bank Card Validator API

Validate and mask common mainland China identifiers in privacy-safe batches. This Actor works as a China ID card validator, Unified Social Credit Code (USCC) checker, bank card Luhn validator, mobile number format checker, and China postal code validator without calling external identity databases.

Use it for data-quality checks, CRM imports, onboarding pre-validation, form validation, compliance workflows, and ETL pipelines. It performs deterministic format and checksum validation only; a valid result does not prove that a person, company, account, or address exists.

Quick start

Run the Actor with one or more records. Use your own id value to join each result back to the source record without exposing the raw identifier in the output.

{
  "records": [
    {"id": "customer-1", "type": "residentId", "value": "11010519491231002X"},
    {"id": "company-1", "type": "socialCreditCode", "value": "YOUR_CODE"},
    {"id": "phone-1", "type": "auto", "value": "13800138000"},
    {"id": "postal-1", "type": "postalCode", "value": "100000"}
  ]
}

Up to 1,000 records can be validated in one run.

Common use cases

• Pre-check Chinese identity card numbers before CRM or ERP imports.
• Validate Unified Social Credit Code structure and checksum for company records.
• Detect malformed mainland China mobile numbers and postal codes.
• Run Luhn checksum validation on bank card numbers before downstream processing.
• Mask sensitive identifiers while retaining machine-readable validation results.
• Add deterministic validation to n8n, Make, Zapier, API, and data pipeline workflows.

Supported identifiers

• 18-character China resident ID card numbers under GB 11643-1999.
• 18-character Unified Social Credit Codes (USCC) under GB 32100-2015.
• Mainland China mobile phone number structure.
• Bank card number length and Luhn checksum.
• Six-digit mainland China postal code structure.
• Automatic type detection when the structure is distinctive.

Privacy-first behavior

• Raw input values are processed in memory and are never copied into dataset items.
• Every output contains only a masked representation.
• The Actor does not log identifier values.
• No external verification, lookup, or identity database is contacted.
• Validation does not prove that a person, company, account, or address exists.

Only process identifiers when you have a lawful purpose and the required consent. Identity numbers and financial account information may be sensitive personal information.

Output

• status: valid or invalid.
• requestedType: type supplied by the caller.
• detectedType: validator that was applied.
• maskedValue: privacy-safe representation.
• isValid: final deterministic result.
• checks: individual format, date, sequence, or checksum checks.
• errorCodes: stable machine-readable reasons for invalid results.
• disclaimer: reminder that format validation is not identity verification.

Limitations

• Resident ID validation checks structure, birth date, sequence, and checksum. It does not query government records.
• Social Credit Code validation checks the permitted character set and checksum. It does not query the National Enterprise Credit Information Publicity System.
• Mobile prefixes change over time, so the Actor intentionally validates only the broad mainland mobile structure.
• A valid Luhn checksum does not prove that a bank card was issued or is active.
