It&#x27;s very important to use accurate classifications, because they&#x27;re used to route your cases to specialists who can help you. A classification always has an ID that is its unique identifier. A valid ID is required when creating a case.

To retrieve valid classification IDs for case creation, use `caseClassifications.search`. Classification IDs returned by `caseClassifications.search` are guaranteed to be valid for at least 6 months. If a given classification is deactiveated, it will immediately stop being returned. After 6 months, `case.create` requests using the classification ID will fail.
