policyid

PolicyId (policy identifier) is a term used across domains to refer to a stable reference for a defined policy or policy-based rule set. The exact meaning varies by context, but in general it denotes a unique identifier used to locate, reference, or enforce a specific policy within a system.

In insurance, a policy ID is a unique alphanumeric code assigned to an individual insurance contract. It is used to locate policy records, manage claims, and verify coverage. Policy IDs are typically generated by the insurer’s systems and may differ from customer-facing policy numbers, serving as an internal reference for policy administration.

In blockchain, policyId most commonly refers to Cardano’s minting policy identifier. It is the hash of the monetary policy script that governs minting and burning of a group of native tokens. The policy ID, together with the token’s asset name, uniquely identifies a token under that policy. The ID remains fixed while the policy script is unchanged; creating a new policy script yields a new policy ID. Wallets and explorers display the policy ID to help users verify token provenance.

In information technology and regulatory contexts, a policy ID may denote a reference to a specific policy document or rule within an organization’s governance framework. Because policy IDs function as keys to policy data, they support auditing, searchability, and interoperability across systems.
