# CreatePolicyVersion
<a name="API_CreatePolicyVersion"></a>

Creates a new version of the specified AWS IoT policy. To update a policy, create a new policy version. A managed policy can have up to five versions. If the policy has five versions, you must use [DeletePolicyVersion](API_DeletePolicyVersion.md) to delete an existing version before you create a new one.

Optionally, you can set the new version as the policy's default version. The default version is the operative version (that is, the version that is in effect for the certificates to which the policy is attached).

Requires permission to access the [CreatePolicyVersion](https://docs.aws.amazon.com/service-authorization/latest/reference/list_awsiot.html#awsiot-actions-as-permissions) action.
