# Address Verification

> Submit a customer's address for verification against government and financial records.

The Address Verification endpoint initiates a verification of a customer's residential address. It cross-references the provided details against identity records and returns an initial verification status with a reference ID for tracking.

<Note>
  Address verification is asynchronous. You will receive a `reference` in the response — use the webhook or the [Digital Address Confirmation](/v3/kyc/nigeria/Digital_Address_Verification_Confirmation) endpoint to get the final result.
</Note>
