# DeletePolicyVersion
<a name="API_DeletePolicyVersion"></a>

Deletes the specified version from the specified managed policy.

You cannot delete the default version from a policy using this operation. To delete the default version from a policy, use [DeletePolicy](https://docs.aws.amazon.com/IAM/latest/APIReference/API_DeletePolicy.html). To find out which version of a policy is marked as the default version, use [ListPolicyVersions](https://docs.aws.amazon.com/IAM/latest/APIReference/API_ListPolicyVersions.html).

For information about versions for managed policies, see [Versioning for managed policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/policies-managed-versions.html) in the *IAM User Guide*.
