NL Onboarding

NL onboarding is governed by Anti-Money Laundering (AML) directives and local regulatory requirements across EU member states.

These regulations require:

• Verification of business existence
• Identification of Ultimate Beneficial Owners (UBOs ≥ 25%)
• Identification of authorized representatives
• Identity verification of applicants and required stakeholders

As a result:

• Registry lookup may be used for corporate verification

• Document submission may be required

• Compliance approval may be required before activation. Manual review may occur when:

  • Registry lookup fails
  • Electronic verification fails
  • Required stakeholder roles are missing
  • Ownership structures are complex
  • Documentation is incomplete or inconsistent

Responsibility

Client responsibilities

The client's onboarding responsibilities include:

• Collect accurate business and stakeholder information
• Declare all required stakeholder roles
• Declare UBOs (≥ 25% ownership)
• Capture applicant attestation
• Upload required documents
• Ensure stakeholders complete identity verification

Nium responsibilities

Nium's onboarding responsibilities include:

• Retrieve registry information (when eKYB is used)
• Validate identity and document submissions
• Conduct compliance checks
• Raise RFIs (Requests for Information) if required
• Approve or reject onboarding

Onboarding Flow

Nium supports both Electronic KYB (eKYB) and Manual KYB for NL region. Electronic KYB retrieves publicly available company information from EU registries. It helps to:

• Pre-fills corporate data
• Reduces document collection requirements
• Improves customer experience
• Speeds up approvals

Step 1: Fetch public corporate details

Collect:

• businessRegistrationNumber
• countryCode

Use the Fetch Public Corporate Details request.

Store the returned publicDetailsId.

If no details are returned, proceed with manual KYB using Create Customer v5.

Step 2: Fetch exhaustive corporate details

Use the Fetch Exhaustive Corporate Details request and include the publicDetailsId.

Store the returned searchId.

note: This is a chargeable API. Use it only once per customer.

Step 3: Verify and complete corporate details

• Confirm submitted data with the applicant
• Verify directors and UBO information
• Collect any missing required information
• Add stakeholder details

Stakeholders may complete verification electronically or manually.

Step 4: Upload required documents

Document upload is required when:

• searchId is not provided
• Registry data is incomplete
• Additional documents are requested during review

Use the Create a File request to upload the required documents. For more information, see Uploading documents.

The response returns a fileId.

This fileId must be referenced in the onboarding request.

For a complete list, see NL Required Documents.

Step 5: Applicant declaration

The authorized representative must confirm:

I certify that I am an authorized representative of the customer.
All information and documents provided are complete and accurate.
I confirm that all UBOs have been disclosed and that I have accepted the Nium Terms and Conditions.

Capture via clickwrap and submit:

• applicantDeclaration
• applicantDeclarationTimestamp (format: YYYY-MM-DD HH:MM:SS)

Step 6: Submit onboarding request

Use Create Customer v5 and include:

• Corporate details
• Stakeholder details
• searchId (if applicable)
• Uploaded fileId references for documents

If searchId is omitted, the application proceeds through manual review.

Once application is submitted:

status	substatus
pending	awaiting_kyc

Step 7: Complete Identity Verification of applicant/ stakeholders

The applicant accesses Nium’s Pre-built KYC form. Access is protected by a One-Time Password (OTP) sent to the registered email address of the applicant.

NL onboarding supports Biometric KYC for:

• Individual customers
• Corporate applicants
• Directors
• UBOs
• Required stakeholders

Manual document upload is also available for stakeholders when required.

Available verification options:

Individual type	Biometric	Manual
Applicant (or individual customer)	Yes	No
Stakeholder (Representative/ Signatory)	Yes	No
Stakeholder (UBO/ Trustee/ Partner)	Yes (preferred)	Yes

See NL Required Documents for more information on POI/ POA documents

Step 4: Compliance review

After KYC completion:

status	substatus
pending	under_review

Nium’s compliance team reviews submissions offline. If additional information is required:

• An RFI is raised
• The customer responds via the RFI Hosted Form

Webhook notifications are sent for all status transitions. For next steps based on application status, see Customer Onboarding Lifecycle.

Multi-layer ownership

If the customer has a multi-layer ownership structure:

• All corporate stakeholders owning ≥ 25% (directly or indirectly) must be declared.
• Corporate structure documentation must be submitted to validate the ownership chain.

For more information, see Multi-layer ownership structure.
