Verification of Payee

From October 9, 2025, Nium must comply with the EU’s Instant Payments Regulation, which requires clients to perform a Verification of Payee (VoP) on all EUR Local payouts.

This guide helps explains:

• What changes are happening.
• How payouts will change.
• How to use Nium Verify to improve success rates (optional).

What’s changing

• All EUR local payouts will be required to perform a verification of payee check.
• The check validates that the beneficiary name matches the account holder's name at the destination bank.
• By default, if the names do not match, the payout will be rejected.

note

Nium will perform a verification of payee check on every eligible EUR Local payout, regardless of whether you submit a request to the Nium Verify endpoint.

Client actions

Override handling

• Default (no action): Mismatched payouts will be rejected.
• Enable override in Nium Portal: Mismatched payouts will proceed, and your organization accepts liability.

To enable the EU override in Nium Portal:

1. Log in to Nium Portal.
2. Click to Configuration. → Client settings → Verification of Payee Override.
3. Toggle Override default.
4. Review and accept Terms & Conditions.

Verify beneficiaries

To minimize rejections and provide a smoother experience, use the Nium Verify endpoint to verify names before creating payouts.
