What Is a Policy ID?
A Policy ID is a unique identifier assigned to a set of assets minted on the Cardano blockchain. Every NFT or fungible token on Cardano is associated with a Policy ID, which defines its minting rules and ensures its authenticity.
Why Are Policy IDs Important?
Authenticity & Verification – A Policy ID helps buyers confirm that an asset belongs to a legitimate collection.
Minting Rules & Supply Control – A Policy ID can enforce rules, such as whether new assets can be minted under the same policy.
Marketplace Recognition – NFT marketplaces, including JPG Store, use Policy IDs to identify collections and prevent fakes.
You can check a collection’s Policy ID on JPG Store by visiting the collection page, where it is displayed near the collection details.
How Are Policy IDs Created?
A Policy ID is generated when a user mints assets on the Cardano blockchain. The process involves setting specific minting policies, which can define whether the policy remains open (allowing future minting) or when it becomes locked (preventing any new assets from being added).
Ways to Get a Policy ID
There are several ways to obtain a Policy ID depending on your skill level and needs:
1. Using JPG Store’s Minting Platform (Recommended)

2. Using Other Minting Platforms
Many third-party Cardano NFT minting platforms also provide Policy IDs when you create a collection. Some platforms allow you to set custom minting rules or provide other features.
3. Generating Your Own Policy ID as a Developer
For users with technical knowledge, you can generate your own Policy ID by interacting with the Cardano blockchain via command-line tools or smart contract development platforms like Plutus.
Requires familiarity with Cardano CLI, Plutus, or other developer tools.
Gives full control over policy rules (e.g., time-locked policies or open-ended minting).
Typically used by advanced creators or developers managing custom minting solutions.
If you generate your own Policy ID, you’ll need to ensure it is properly registered and recognized when submitting your collection for verification on NFT marketplaces like JPG Store.
How to Verify a Policy ID?
To verify an NFT’s authenticity, always check its Policy ID against the official collection page on JPG Store or by using a Cardano blockchain explorer like:
This helps confirm that the NFT was minted under the correct Policy ID and is not a counterfeit.
