Identity verification against government databases and official records in Spain

Key takeaways (TL; DR)
 

Validating identity data against official government databases in Spain adds a critical security layer to your KYC and AML process.

Didit enables automated checks of personal data—like DNI number, name, or expiration date—directly against trusted official records.

This capability is available both via API (Standalone) and No-Code Workflows, making integration fast for technical and compliance teams alike.

Didit’s Database Validation improves accuracy, reduces fraud, and supports compliance with Spain’s Law 10/2010 and EU AMLD6 guidelines.

Identity verification in Spain is evolving fast. Companies can no longer rely only on validating an ID document or a selfie: fraud keeps leveling up, and they need to ensure the information submitted by the user is real. The best way to do that is to check it against official records.

This process is known as Database Validation (or validation against government databases) and adds an extra layer of security to user verification. In regulated environments, it’s quickly becoming a new compliance standard.

In this article, you’ll learn how Didit enables validation against Spanish government databases, both through API (Standalone) and No-Code Workflows—adding more trust and accuracy to identity verification without introducing extra friction for users.

Why this matters for KYC compliance

Spain’s regulatory framework requires any financial or regulated entity to know its customers. That means companies operating in higher-risk environments must verify user identity before starting any business relationship.

Spain’s Law 10/2010 on the prevention of money laundering and terrorist financing sets the foundation for this verification: user-provided information must be accurate, up to date, and verifiable.

In most cases, a document verification step (DNI, passport, driver’s license, etc.) plus biometric checks to confirm the person is the legitimate document holder may be enough. However, document verification doesn’t guarantee the authenticity of the underlying data or whether it’s still valid. In fact, synthetic identities often exploit gaps in many providers’ checks to slip through.

To counter this, leading compliance teams in Spain are increasingly adopting cross-validation with official databases—a practice recognized by SEPBLAC and aligned with EU AMLD6 guidelines.

With Database Validation, user-declared data (like document number, document type, or expiration date) can be automatically matched against trusted government records—creating auditable evidence and significantly reducing fraud risk.

How Didit Database Validation works

Database Validation acts as an additional layer in your identity verification flow. When a user submits their personal details, Didit automatically runs a direct 1:1 comparison between the captured data and the available government databases.

Step-by-step: validation against government databases

1. Data extraction. When a user captures their identity document, our system sends the key fields.
2. Data integrity check. The system verifies the required information was correctly extracted.
3. API call. A request is made to the government source.
4. Result. The response is evaluated and returned as a match type (Full_Match, Partial_Match, or No_Match). Depending on your configuration, the session can be auto-approved, auto-rejected, or routed to manual review.

API or No-Code: two paths to the same security

Didit Database Validation combines flexibility with robust coverage. You can integrate it in two ways: via No-Code Workflows or standalone APIs. Either way, you get speed, accuracy, and compliance.

No-Code Workflows

Built for compliance and operations teams that want to launch quickly without engineering work.

• Design the full flow from Didit’s visual builder.
• Enable validation against official databases with a single click.
• Centralized results with one-click export.

Standalone API

Ideal for technical teams who want to embed data validation directly into their architecture for maximum control.

• Modern, well-documented REST API. See our technical documentation.
• Real-time responses.
• Full control over flows and logic.
• Supports individual or bulk validations.

Which Spanish documents and fields can Database Validation verify?

When you run identity verification against government databases in Spain using Didit Database Validation, the goal isn’t simply to confirm that a document exists—it’s to validate key personal data fields against trusted records. This cross-check adds strong supporting evidence, strengthens the user’s identity profile, and significantly reduces fraud and inaccurate information.

Supported documents in Spain and verified fields

In Spain, the compatible document for this type of validation is the Documento Nacional de Identidad (DNI). It’s used as the input to query the relevant government sources.

As for the fields verified, Database Validation checks essential user identifiers against official records, including:

• Document number (DNI), the unique identifier for the individual.
• Document type, to ensure the correct document category is being validated.
• Expiration date, to confirm the document is still valid.
• First and last name, to compare the level of match in the official record.

This ensures the information provided by the user exists, is current, and matches trusted government sources in Spain.

You can see other supported countries and document types in our documentation.
