Can I change the delivery address or
recipient for my international express shipment?

It depends on the carrier and the stage of the shipment. In most cases, it's possible to change the delivery address or recipient for an international express shipment, but it may not be possible once the shipment has already left the origin country or is in transit.
If you need to change the delivery address or recipient, it's best to contact the carrier (or CFM) as soon as possible. They will be able to tell you if a change can be made and what the process and fees, if any, will be.
Keep in mind that changing the delivery address or recipient can impact the customs clearance process and may result in additional fees or delays. It's a good idea to check with your carrier (or CFM) and/or a customs broker for specific information on the requirements and regulations that may apply.
