# ID Pass validation strategies

ID Pass is Global Data's Australian KYC identity verification service. You create a one-time verification link, your customer completes a guided online check, and you retrieve a clear pass/fail result plus the verified identity details. For a full overview of how ID Pass works - including liveness, biometric face match, configuration options, and the customer experience - see the [ID Pass Overview](/docs/guides/idpass).

When you create an ID Pass, you choose a document verification strategy via the `document_verification` parameter. The strategy determines how each identity document is checked and what is returned in the response. ID Pass supports three strategies:

- [**ID Pass - DVS mode**](id-pass---dvs-mode) (default) - Full verification via the Australian Document Verification Service (DVS), with the DVS result codes and details returned to you.
- [**ID Pass - IDSP mode**](id-pass---idsp-mode) - DVS verification performed by Global Data on your behalf. An opaque identity opinion (valid / not valid) is returned; DVS result codes and details are not exposed.
- [**ID Pass - Basic mode**](id-pass---basic-mode) - Format and checksum validation only. No DVS call is made.

Each section below is a self-contained quick start for that strategy.
