ID formats
Use ID format references safely
A format can help a UI explain expected input, but it cannot establish that a value belongs to a person or was issued by an authority.
Use sources at the country page
Public identity formats vary by country and program. Review the source links on the relevant country page before using a reference in documentation or a test fixture.
Never turn a reference into an identity workflow
g3n-data intentionally avoids validation and usable ID generation. Keep examples masked, avoid collecting real IDs in test systems, and use an authorized verification service when a product genuinely requires identity proofing.
