    {"type":"BR_CPF","value":"52998224725","valid":true,"formatted":"529.982.247-25","normalized":"52998224725"}

    Important: "valid" means the number is well-formed (structure, length and check digit). It does not confirm the person or company is registered or active with Receita Federal or AFIP/ARCA.

    Next steps

    • Store the normalized value in your database and show formatted in the UI
    • Ask the customer to re-enter the invalid CPF
    • For KYC, confirm registration status with the relevant tax authority

    Connects securely to your tools. The creator never sees your data.

    About this skill

    What it does

    • Auto-detects document type (AUTO, optional country hint)
    • Returns valid/invalid, canonical formatted value, digits-only normalized value and a clear error reason
    • Batch validation of up to 1,000 items (great for CSV / CRM cleaning)
    • Generates synthetic, check-digit-valid fake test data for QA

    Use cases

    Note: "valid" means well-formed (structure + check digit), not registered with the tax authority.
