ECZ-ID Specification

The ECZ-ID is a globally unique, time-bound business identifier issued under formal authority and enforced through resolver logic. This specification defines its format, constraints, and validation model.

Example ECZ-ID: ECZ-GB-A93K7Q — stable, non-semantic identity spine

Example child passport: ECZ-GB-A93K7Q::D2-DRONE-Q8Z4M3 — derived, scoped state object

Resolver URL: /p/ECZ-GB-A93K7Q/D2-DRONE/Q8Z4M3

Identifier Format

  • Each ECZ-ID is a fixed-length alphanumeric string with embedded issuance epoch.
  • It is globally unique, stable, and resolver-governed.
  • No tiers, versions, or meanings are encoded in the ECZ-ID.

Validation Constraints

  • All ECZ-IDs must resolve to authoritative state at the time of reference.
  • Expired or revoked identifiers are non-canonical and must not be cited in contracts or systems.
  • Resolution includes status, issuance time, and cryptographic links to passports (if any).

ECZ-IDs are designed for long-term reference across jurisdictions. They are not used for branding, messaging, or scoring.

All validity is resolver-bound. No identifier is canonical unless it resolves.
