No MRZ extracted

With API version 2024-11-30 (GA) and the prebuilt-idDocument model, European ID cards and driver licenses are supported as document types, but the documentation does not list MRZ (machine-readable zone) lines on EU ID cards as dedicated, structured fields.

The behavior observed—no MRZ extracted for new European ID cards, even when tested directly in Document Intelligence Studio across multiple countries—is consistent with the currently documented capabilities. The ID model has expanded support for EU IDs (as noted in the February 2024 updates), but this expansion is described in terms of document and field coverage in general, not MRZ-specific extraction.

Given the available information, MRZ on European ID cards is not exposed as a specific field in the prebuilt-idDocument model output in v4.0 (2024-11-30 GA).

To work with MRZ data in this scenario:

1. Confirm current behavior
   • Use Document Intelligence Studio with Model ID: prebuilt-idDocument and inspect the full JSON result to verify that MRZ is not present as a named field. This matches current documentation.
2. Use generic text extraction as a workaround
   • If the MRZ is visually present on the card, process the same image with a general text/structure model (for example, a layout/read-style model from Document Intelligence) and then parse the MRZ in custom code.
3. Track feature evolution and submit feedback
   • The ID document model is actively evolving (for example, “expanded field support for European Union identification cards and driver licenses” in the February 2024 release notes). Monitor the ID document model and What’s new pages for any future announcement that adds explicit MRZ extraction for EU IDs.
   • If MRZ extraction for European ID cards is a key requirement, submit it as a feature request through Azure support/feedback channels so it can be considered for future updates.
