note

Submit notarized business registration documents whenever possible. Non-notarized documents may delay approval as Nium verifies them from the source.

Additional business documents​

Submit the following documents when applicable:

REGISTER_OF_DIRECTORS and REGISTER_OF_SHAREHOLDERS​

Provide this document if the business registration document does not include a list of directors or shareholders. For faster approval, submit notarized copies.

When using eKYB:

  • Include this document if a new director or shareholder is added who isn’t in the stakeholder list returned by the Exhaustive Details endpoint..
  • If omitted, Nium will raise a **Request for Information (RFI).

PROOF_OF_BUSINESS​

Submit this document if no website is provided. It helps Nium verify the customer’s business activity. Accepted documents include:

  • Product catalog, brochure, marketing material, or business plan (preferred).
  • Contract, business agreement, or vendor agreement.
  • Photo of a physical store.
  • Invoice describing business operations, issued within the last year not preferred.

CORPORATE_STRUCTURE (Ownership Structure)​

Submit this document if the company has multiple ownership layers. It should include the names and share percentages of all shareholders to identify the ultimate beneficial owner (UBO).

Stakeholder documents​

Stakeholders such as SIGNATORY, REPRESENTATIVE, ultimate beneficial owners (UBOs), TRUSTEE, or PARTNER can verify their identity through manual KYC or electronic KYC (eKYC).

Electronic KYC​

Submit:

  • A live selfie with a valid passport or national ID.
  • Source of wealth, if isPEP is true.

Manual KYC​

Submit:

  • A color copy of a valid passport or national ID (black-and-white copies are not accepted).
  • Source of wealth, if isPEP = true.

All manual KYC documents undergo fraud checks. If Nium cannot verify authenticity, an RFI will be raised.

Source of wealth​

If any shareholder is a Politically Exposed Person (PEP), include a document that explains the source of their wealth. This helps confirm the legitimacy of the funds used to operate the business.

Include a written explanation and supporting documents:

  • Bank statements (personal or joint).
  • Employment income (salary, bonuses, or pension).
  • Loan or contract agreements.
  • Sale of assets (property or shares).
  • Inheritance or family wealth transfer.
  • Legal settlement compensation.
  • Profits or returns from legitimate businesses or investments.
  • Documents showing ownership of businesses or investments.
  • Other financial documents showing lawful income or assets.

Applicant documents​

Applicants (individual customers) must always complete electronic KYC.

Submit:

  • A live selfie with a passport (for non-EU citizens) or passport/national ID (for EU citizens).
  • Power of Attorney, certified by Apostille, if the applicant is not a company director.
  • Source of wealth, if isPEP = true.
