UPDATE: The launch date has changed from April 5, 2021 to April 19, 2021.
What is changing?
Today, sellers are required to provide the carrier name when confirming shipment through the Manage Orders page on Seller Central. We are making the following changes to the shipment confirmation process:
April 5,April 19, 2021, sellers will be required to provide a value for the CarrierCode field (carrier name) when confirming shipments via bulk feeds, APIs, or integrations.
Note: If the seller is using an unlisted carrier, they can use the CarrierCode value of ‘Other’ and then provide the carrier name in the CarrierName field.
- POST_ORDER_FULFILLMENT_DATA will change the CarrierCode field from optional to required. The CarrierName field changes to optionally required when CarrierCode is set to ‘Other’.
Flat file template:
- POST_FLAT_FILE_FULFILLMENT_DATA will change the carrier-code field from optional to required. The carrier-name field changes to optionally required when carrier-code is set to ‘Other’.
April 5, April 19, 2021, Sellers who do not provide this information will not be able to confirm shipments and can experience an increase in their late shipment rate (LSR) and an increase in automatically canceled orders due to unconfirmed shipments.
This change does not apply to Buy Shipping. Amazon automatically collects data on the carrier and ship method used via Buy Shipping.
Which marketplaces are affected?
This change applies to the Canada, US,
Japan, India, Australia, Singapore, Brazil, and Mexico marketplaces.
Note: This change takes effect April 15, 2021 for the Japan marketplace.
Who is affected?
Developers with applications that confirm shipments are affected.
What action is required?
If you have an application affected by this change, be sure to update your application workflow to require the CarrierCode value. If the CarrierCode value is set to ‘Other’, then conditionally require the CarrierName value.
