Amazon Empowers Sellers to Link Multiple Carrier Accounts on Buy Shipping
New update offers greater flexibility, access to negotiated rates, and streamlined fulfillment for merchants.
An important update recently appeared on the Amazon Seller Central platform that could significantly benefit many sellers. Amazon is now allowing sellers to link their own FedEx and UPS accounts directly to the Amazon Buy Shipping service.
This change means you are no longer limited to using Amazon's standard shipping rates through Buy Shipping for these carriers. Instead, you can leverage the specific rates and terms you have negotiated directly with FedEx and UPS.

Previously, while Buy Shipping offered convenience and certain protections, sellers with favorable negotiated rates with FedEx or UPS often had to purchase labels outside of Buy Shipping to utilize those rates. This new feature bridges that gap. By linking your accounts, you get the best of both worlds: your negotiated rates and the advantages of using Amazon Buy Shipping.
Step-by-Step Guide to Linking Your Carrier Accounts
1. Navigate to Buy Shipping Preferences
Go to your Seller Central dashboard, select “Preferences” under Buy Shipping, then click “Manage your carrier accounts.”
2. Choose and Link an Account
Select the FedEx or UPS account you wish to integrate and click “Link account.”
3. Enter Required Information
Fill in your carrier account credentials, negotiated rate details and any warehouse assignments.
4. Submit and Verify
Hit “Submit” and confirm that Amazon can now retrieve your rates and shipping labels automatically.

Key Benefits of Linking Your Carrier Accounts
Linking your existing FedEx and UPS accounts to Amazon Buy Shipping offers several valuable advantages:
1. Use Your Negotiated Rates: The primary benefit is access to your specific, negotiated shipping rates with FedEx and UPS. This can lead to potential cost savings on your shipping expenses.
2. Account Health and Claims Protection: Using your linked account through Buy Shipping can contribute to your account health and potentially help you avoid "Package didn’t arrive" claims under Amazon's policies, similar to using Amazon's default Buy Shipping options.
3. Streamlined Fulfillment: Link one or more accounts for each carrier. If you operate multiple warehouses, you can assign specific linked carrier accounts to each location. This streamlines your logistics by ensuring the correct account (and rates) are used depending on the shipping origin.
4. Flexible Workflow: Access and use your linked carrier accounts when purchasing labels through your preferred channels, including directly in Seller Central, via the Amazon API, and through multichannel integrators that support Buy Shipping.
Additional Tips for a Smooth Setup
• Ensure your FedEx and UPS accounts are active and in good standing before linking.
• Review any rate changes periodically in Seller Central to keep your negotiations up to date.
• If you use multiple warehouses, assign carrier accounts strategically to balance cost and delivery speed.
• Consult Amazon’s “Manage your carrier accounts” help page for troubleshooting or carrier-specific requirements.
By linking your own carrier accounts on Buy Shipping, you gain greater control over your shipping costs and customer experience. This Seller Central announcement marks a significant step toward more flexible, seller-driven fulfillment—empowering you to optimize every shipment with the carriers you trust.
