A Breakdown of Vendor Central Advance Shipment Notification Trainings: December 2021


On December 13, Amazon announced that new Advance Shipment Notification (ASN) trainings are available in Vendor Central, and that they are “strongly recommending” Vendors to review this information.

It’s not always easy to keep up with each training that Amazon rolls out, so we decided to put together this update to help break it down for you.

What is an ASN?

An ASN is a virtual record of your shipment, and they are a requirement. Vendors send ASN’s to communicate the contents of each shipment, the tracking number, and any carrier information. ASN’s increase the speed at which Amazon can get the shipment contents live for sale on Amazon.com. You should submit your ASN as soon as the shipment leaves your facility.

There can only be one ASN per shipment/truckload (if your shipment is more than a truckload you must create a separate shipment, therefore getting a separate ASN). You cannot cancel ASN’s, however, they can be edited for a brief period (one week). You must be sure that the ASN content matches the actual shipment contents. Be sure to carefully fill out all the details - it is good practice to double-check to be sure.

How to Create an ASN

In Vendor Central, navigate to Orders > Shipments. In the top right corner, click “Create a Prepaid ASN.”


Here, you can create an ASN by filling out the form.


Or, if you prefer, you can use a spreadsheet instead, which is available for download at the top right corner of the page.

To gain a deeper understanding of how ASN’s work, why they are necessary, as well as the entire Vendor Central shipment process in general, we recommend utilizing the Training Centre - which covers topics from Getting Started to Safety and Compliance. If you have specific questions regarding ASN’s, please feel free to contact our team of experts.
