Hello @global16,

Thank you for contacting Amazon forums, this is Lucre it's a pleasure to assist you!

I understand you're wondering about the status of a missing shipment, from what you're mentioning I'm not certain if you refer to a shipment that hasn't been delivered or a shipment that was delivered but there's missing units.

Also know, when a fulfilment centre encounters a problem with receiving one or more of your products, we will notify you by email and flag the problem in your Shipping Queue. You can also review problems in the Inbound Performance report. You can use this information to help determine for all of your shipments within the time frame covered by the report which products have had problems and follow the coaching instructions to correct related issues.

For more information, you can visit this help page.

If you're referring to a missing delivery, I recommend you to check tha tracking number from your package to review where shipment is located and to discuss with your carrier in case you have any question.

Now, if you're referring to missing units from a shipment already delivered in the fulfillment center, please know you can use the Shipment Reconciliation tool to fix discrepancies.

Please review the below help pages to learn more about this:
