# Marking an issue as blocked or unblocked
<a name="issues-mark-as-blocked"></a>

If something is preventing you from working on an issue, you might want to mark it as *blocked*. For example, your issue might be blocked if it relies on a change to another part of your code base that hasn't been merged yet.

When you mark an issue as blocked, CodeCatalyst adds a red **Blocked** label to the issue, making it highly visible in your backlog or archive, or on your board.

You can unblock the issue when outside circumstances are resolved.

**To mark an issue as blocked**

1. Open the issue you want to mark as blocked. For help with finding your issue, see [Finding and viewing issues](issues-view.md).

1. Choose **Actions**, and then choose **Mark as blocked**.

**To unblock an issue**
