Which routing list stamp is mandatory for all travel document types?

The mandatory routing list stamp for all travel document types is "APPROVED." This stamp signifies that the document has undergone the necessary review and has received official authorization for processing. It ensures that all relevant parties are aware that the document meets the required standards and is ready for further action or distribution. Having this stamp is vital for maintaining accountability and transparency in the processing of travel documents, aiding in tracking and compliance with procedural guidelines.

In contrast, other stamps like "REVIEWED," "PENDING," and "CANCELLED" serve different purposes. "REVIEWED" indicates that a document has been examined but may not yet be finalized for processing. "PENDING" suggests that a document is awaiting further action or decision before it can be approved. Meanwhile, "CANCELLED" represents a document that is no longer valid for any further action. Each of these stamps plays a distinct role in the workflow, but only the "APPROVED" stamp confirms that the document is ready to proceed.
