Identity Verification Checks

Identity Data​

Fetches personal data from iDIN (Dutch bank identity verification).

{
  "checkName": "identity-data",
  "importance": "SKIPPABLE"
}

Features​

  • Retrieves verified personal information from banks
  • Includes name, date of birth, and address
  • Highest level of identity verification

Important Notes​

  • Should always be SKIPPABLE because not all banks support iDIN
  • Always include correspondence-data as backup

Retrieved Data​

  • Official first name(s)
  • Last name and prefix
  • Date of birth
  • Gender
  • Address (street, house number, postal code, city)
  • Country code

Correspondence Data​

Collects address and contact information directly from the professional.

{
  "checkName": "correspondence-data",
  "importance": "NOT_SKIPPABLE"
}

Features​

  • Manual entry of address information
  • Backup for when iDIN is not available
  • Contact information collection

Important Notes​

  • Should always be NOT_SKIPPABLE as fallback for identity-data
  • Always include this check in your flow

Collected Data​

  • Email address
  • Phone number
  • Full address details

Identity Document​

Performs OCR on identity documents with optional liveness detection.

{
  "checkName": "identity-document-v2",
  "importance": "NOT_SKIPPABLE",
  "configuration": {
    "applicantLevelName": "id-and-liveness"
  }
}

Configuration Options​

applicantLevelName​

id-only

  • Document scanning and OCR
  • Manipulation detection
  • Data extraction from document

id-and-liveness

  • Everything from id-only
  • Selfie capture
  • Liveness detection
  • Face matching with document photo

Supported Documents​

  • Passports
  • National ID cards

Security Features​

  • Document authenticity checks
  • Manipulation detection
  • MRZ (Machine Readable Zone) validation
  • Face matching accuracy scoring

Best Practices​

Always include all three identity checks for maximum coverage:

"requestedChecks": [
  {
    "checkName": "identity-data",
    "importance": "SKIPPABLE"
  },
  {
    "checkName": "correspondence-data",
    "importance": "NOT_SKIPPABLE"
  },
  {
    "checkName": "identity-document-v2",
    "importance": "NOT_SKIPPABLE",
    "configuration": {
      "applicantLevelName": "id-and-liveness"
    }
  }
]

Why This Combination?​

  1. identity-data provides the highest verification level when available
  2. correspondence-data ensures you always get address information
  3. identity-document-v2 provides document verification and fraud prevention

Handling Edge Cases​

Professional without iDIN access:

  • Falls back to correspondence-data and identity-document-v2
  • Still provides strong verification through document checks

Foreign professionals:

  • iDIN won't be available
  • Identity document provides primary verification
  • Consider making identity-document-v2 SKIPPABLE for international cases

Data Cross-Referencing​

Otentica automatically cross-references data between these checks:

  • Names from iDIN matched against document OCR
  • Dates of birth compared across sources
  • Address consistency verification

Discrepancies are flagged in the results for manual review.
