# Claiming a Component

Components with a match state of `Similar` or `Unknown` may be manually identified by claiming them. Claiming the component stores the identity information against that component's hash to avoid triggering the Component-Unknown policy.

The claim is applied globally so any other application being analysed will benefit from the claim. The component will have a match state of `Exact`, and the Identification Source will be `Manual` in future scans or re-evaluations.

Claiming components may also be done using the [Component Claim REST API](https://help.sonatype.com/en/component-claim-rest-api.html "Component Claim REST API").

- All unknown components may be claimed from any ecosystem. However, the claimed coordinates are limited to the Maven format.

- Security information is matched against the component hash. Claiming a component does not pull security vulnerability data against a public component with that same namespace. However, it may pull in license information from the public component. When license data is not found for that namespace in the next scan, the newly claimed component will violate the `License-None` policy.

To resolve this violation, you can select override or choose any other option as needed. Refer to [Selecting, Overriding, and Editing Licenses](https://help.sonatype.com/en/component-license-information.html#selecting--overriding--and-editing-licenses) for more details.

- You will receive an error when claiming a component with coordinates already in use by another component.
