# Additional Customer Verification

# 

In certain situations, additional evidence is required to verify customers and ensure we’re compliant with the KYC regulations.

If your customers are primarily based in the EU, refer to the section [Onboarding EU Customers](#onboarding-eu-customers) below. Note: this functionality is only available as a closed BETA.

If you are onboarding high risk businesses primarily based in the US, refer to the section [Onboarding High Risk US Businesses](#onboarding-high-risk-us-businesses) below. Note: this functionality is only available as a closed BETA.

## Onboarding EU Customers

If you have customers that meet all the criteria below, then you must implement the steps in this guide to onboard all your new customers.

- You use the [customer account with Partner KYC](/guides/product/kyc/partner-kyc) model (we onboard and create a Wise account for your customers)
- Your customer’s address is in an EEA country
- Your customer creates a quote with source currency for an EEA currency


During onboarding, customers need to provide additional evidence using the [upload-evidences](/api-reference/verification/verificationuploadevidences) endpoint. We will use this to perform an initial automated check before either verifying the customer, or requesting more information. Successful verification will be returned within a few seconds. Unsuccessful verification will create a case for our team to review, so it can take longer to receive an update.

Subscribe to [additional verification state change event](/guides/developer/webhooks/event-types#cdd-check-state-change) webhook to receive updates about your customers' additional verification status. This webhook will also inform you if any further evidence or documents are required to complete the review.

Provide those additional evidence by using [upload-document](/api-reference/verification/verificationuploaddocument) endpoint.

Based on Wise.com average customer base, about 95%* of customers do not need to provide documents or additional information after the initial upload-evidences information is submitted.

## Repapering EU Customers

This functionality is in a closed BETA.

Repapering is the process of performing additional verification for existing customers.

You only need to use this if you began onboarding customers before 1/1/2023 and if you have customers that meet all the criteria below.

- You use the [customer account with Partner KYC](/guides/product/kyc/partner-kyc) model (we onboard and create a Wise account for your customers)
- Your customer’s address is in an EEA country
- Your customer creates a quote with source currency for an EEA currency


The process starts by calling [required-evidences](/api-reference/verification/verificationgetrequiredevidences) endpoint before a transfer is created. This returns a list of required evidence for your customer.
If no evidence is required, then proceed to transfer as usual. Otherwise, if one or more evidences are required, submit those via [upload-evidences](/api-reference/verification/verificationuploadevidences).

The process from that point will follow the flow [Onboarding EU customers](#onboarding-eu). Once verified, the customer may proceed with their transfer.
