Driver’s license validation: a developer’s guide to clear signals
Compare structure, field consistency, source checks, and jurisdiction coverage without overclaiming.
Read the guideBe precise about the relationship you are establishing.
Document structure, field agreement, and a source comparison are not interchangeable with linking an applicant to evidence. These articles help identify the method behind a finding and the questions that remain unanswered. Start with the conceptual guide, then follow the document-specific review relevant to your workflow.
Use a written method and coverage matrix rather than a broad verified label. Include unsupported contexts, incomplete evidence, and operational failures. Each unresolved state needs a defined route, and none should be turned into a claim about intent merely because the application lacks another status.
Each guide includes a primary reference and links to related documentation. Use the articles as a review starting point, then align the recommendations with the actual methods, data, and policies of your implementation.
