# BVN Verification

> Verify Bank Verification Numbers instantly.

The BVN Verification API allows you to validate the bank records of individuals. This is a critical step for KYC (Know Your Customer) in fintech applications.

### Modes

* **Basic**: Essential profile data.
* **Advanced**: Full profile data including residential address and more.

<Tip>
  Identity services can be tested using the Sandbox environment with your `test_...` key. Test requests will return mock data and won't charge your wallet.
