Multi-Source Identity Validation
Don’t let incomplete data stop your onboarding. Verify Legal Identities via NIF, IBAN, or Phone — instantly.
Context
- Client profile: Financial Institutions, Fintechs, Consumer Credit Providers, Telecoms, Utilities
- Regulatory framework: AML (5AMLD/6AMLD), KYC, Bank of Portugal requirements
- Business process: Digital onboarding, Customer Due Diligence (CDD), Direct Debit setup, Account opening
- Core need: Obtain verified Legal Full Name for sanction screening and fraud prevention
Credit Institutions access consumer credit information at Banco de Portugal through the CRC (Central de Responsabilidades de Crédito) as part of their credit risk assessment process.
Challenge
Compliance teams struggle with incomplete data. A NIF alone might verify a tax ID exists, but it doesn’t prove the person standing in front of you (digitally) is who they claim to be.
- Data Gaps – Standard NIF queries often return “No Name Found” or partial matches — only 20-30% success rate
- Verification Silos – Companies have phone or IBAN, but no way to link them to the Legal Name required for AML screening
- High Friction – When automated checks fail, businesses resort to manual KYC (ID photos), leading to abandoned applications
- Payment Fraud – Setting up SEPA Direct Debits on accounts that don’t belong to the applicant
Why Full Name Validation Matters:
- Sanction Screening: You cannot check if “John Doe” is on a terrorist watch list if the user signs up as “J. Doe” or uses a nickname
- Identity Theft Prevention: Fraudsters often use a real NIF but their own phone number or bank account
- Synthetic Identity Fraud: Criminals mix real and fake data — cross-referencing IBAN to name ensures the person getting the credit is the account owner
Solution: bizAPIs Identity Waterfall
The bizAPIs service acts as a single point of truth. It accepts any combination of identifiers — NIF, Phone Number, or IBAN — and runs intelligent cross-referencing logic to return the most accurate legal name available.
How it works
| Input | Output | Use Case |
|---|---|---|
| Phone-to-Name | Registered legal name | Confirms the “Digital Footprint” matches the applicant |
| IBAN-to-Name | Account holder’s name | Ensures Direct Debit mandates are legally valid |
| NIF-to-Name | Tax-registered legal name | Standard tax authority verification |
| Hybrid Logic | Best available name | Automatically pivots to Phone/IBAN if NIF fails |
Key Value Pillars
