### Common use cases

Multi-Bureau Checks are typically used for:

* **No-document identity verification**: Validate customer identity without requiring an ID document upload.
* **Cross-source identity validation**: Match customer details against multiple trusted data providers to confirm consistency and accuracy.
* **Credit bureau identity checks**: Perform identity and address verification using credit bureau data where applicable.
* **Fraud risk reduction**: Identify discrepancies across authoritative sources that may indicate synthetic or stolen identities.

### How the check works

ComplyCube searches for a bureau record matching the submitted customer details.

It then verifies identity and address attributes across one or more sources.

You can use the results to support customer due diligence (CDD) decisions.

{% hint style="info" %}
This service includes a **2+2 check** variant that verifies at least two identity attributes with **two or more separate bureaus**. Get in touch with your Account Manager or [contact us](https://www.complycube.com/sales) to enable it.
{% endhint %}

### Analysis performed

ComplyCube verifies key customer details against multiple [trusted sources](#about-service). This improves confidence in the accuracy of identity and address data.

**Verifiable attributes** include:

1. Name
2. Date of birth (DOB)
3. Address
4. ID number (e.g. SSN, Social Insurance Number, National Identity Number, or Tax Number)

By default, customer details are considered verified when at least the **name** and **one additional attribute** match in a bureau record. This verification can occur in one of the following ways:

1. Name + DOB match
2. Name + Address match
3. Name + ID number match

{% hint style="info" %}
ComplyCube will attempt to match all attributes if possible: **name**, **address**, **DOB**, and **ID number**.
