DOCUMENT DATA · VALIDATION GUIDE

Passport validation API

Plan passport data checks with explicit capture, consistency, and verification boundaries. A machine-readable result should still be understandable to people.

Read the signals. Respect the limits.

ILLUSTRATIVE SIGNALS · NOT A LIVE RESULT

WHAT TO MAKE EXPLICIT

Design around the evidence.

A result becomes useful when its method, limits, and next action are visible together.

01 / SIGNAL DESIGN

Capture context

A supported layout and known input source. Make the method and any unresolved context visible to the consumer.

02 / SIGNAL DESIGN

MRZ consistency

Explicit field and check-digit outcomes. Make the method and any unresolved context visible to the consumer.

03 / SIGNAL DESIGN

Evidence boundary

Authenticity and holder linkage kept separate. Make the method and any unresolved context visible to the consumer.

What this does not establish

A matching MRZ check digit is a consistency signal—not proof that a passport is genuine or belongs to the person presenting it.

Reference: ICAO Doc 9303, Part 3. Reference links explain the underlying distinction; they do not imply a partnership or an enabled source connection.

A CONTRACT YOU CAN DISCUSS

Read the example.
Review the assumptions.

Switch between the fictional request and response. The example records structure separately and leaves real-world verification unperformed.

Proposed route: POST /v1/validate/passport. This is a design example, not an available network endpoint.

PLAN THE NEXT STEP

Keep the workflow human.

Ask for correction.

Point to the missing context or affected field. Preserve the person’s intended value until a meaningful change is reviewed.

Make review explicit.

Separate incomplete evidence from negative findings. Assign ownership and provide a real path for resolving uncertainty.

Prepare for unavailability.

A dependency problem needs an operational route. Do not ask users to keep editing information that was never checked.

Explore another data family.
