# Proof of Address Check

### About service

Proof of Address (PoA) Check is a **document-based address verification** service for **KYC** and customer onboarding.

It uses ComplyCube’s OCR and decision engine to extract address details from PoA documents. It then verifies the extracted data against customer-provided information and geolocation signals.

#### Supported proof of address documents

This service supports the following PoA document types:

* Bank statements
* Utility bills
* Driving licenses
* Tax documents

We recommend running this type of check through our [Hosted Solution](https://app.gitbook.com/s/lv7UhJvTbxeq4s3KwQpn/web-integrations/hosted-solution-quick-guide), [Web SDK](https://app.gitbook.com/s/lv7UhJvTbxeq4s3KwQpn/web-integrations/web-sdk-quick-guide), or native [Mobile SDKs](https://app.gitbook.com/s/sw26JqCBnT6AEIbxAYyk/quick-guides/mobile-sdk-guide). This enables ComplyCube to perform additional analysis on the submitted proof of address document.

### Common use cases

Proof of Address Checks are typically used for:

* **Document-based address verification**: Verify a customer’s residential address using proof of address documents (for example, a utility bill or bank statement).
* **KYC onboarding and CDD**: Collect and validate address evidence to support customer due diligence (CDD) requirements.
* **Fraud risk reduction**: Detect mismatches between submitted and extracted address data, suspicious document recency, or anomalous geolocation signals.
* **Audit-ready proof of address evidence**: Capture extracted address details and document metadata to support compliance reviews.

### How the check works

1. The customer uploads a proof of address document (for example, a utility bill).
2. ComplyCube extracts address and document metadata using OCR.
3. The check validates the extracted address against customer-provided details.
4. The check evaluates geolocation signals (for example, IP proximity) to support the decision.

### Analysis performed

The PoA Check extracts and validates a customer’s address details from PoA documents.
