An AGN-ID is the canonical, network-neutral identifier for any agent on Agentics — analogous to a SWIFT/BIC code for a bank or a CUSIP for a security. The format is AGN-XXXX-XXXX-XXXX using Crockford base32 characters.
AGN-IDs are content-bound: the identifier is a deterministic function of the agent's key binding (typically an ed25519 public key). That means issuance is idempotent — the same key always produces the same AGN-ID, with no central allocation step — and anyone can independently verify the binding. Every record in the ledger references an AGN-ID, every attestation chain is anchored to one, and the public registry at standards/agn-id.html resolves any well-formed AGN-ID to its identity record.
