Amazon Improves Shipping Settings Automation Delivery Promises for Seller-Fulfilled Orders — Sellers No Longer Need to Set a Shipping Service Priority
Effective: August 28, 2026
Seller-fulfilled (FBM) sellers in the US store who use Shipping Settings Automation, and sellers who have been holding off on SSA because of the shipping service priority setup step. FBA sellers are unaffected.
On August 28, 2026 Amazon announced that delivery promises for seller-fulfilled orders are now more accurate, following an improvement to how Shipping Settings Automation (SSA) calculates them. The practical change for sellers is that SSA no longer requires you to set a shipping service priority — Amazon derives the promise itself rather than relying on a seller-ranked list of shipping services. SSA already calculates ZIP-code-level transit time from the seller's warehouse to the buyer's address using carrier data, and Amazon has consistently said more accurate promises tend to produce faster displayed delivery dates.
Key Points
- Announced August 28, 2026: Amazon improved how Shipping Settings Automation sets delivery promises for seller-fulfilled orders, making those promises more accurate
- Sellers using SSA no longer need to set a shipping service priority — that configuration step is removed from the delivery-promise calculation
- SSA dynamically calculates ZIP-code-level transit time from your warehouse to the buyer's address using up-to-date carrier data, instead of manual region-by-region estimates
- Amazon periodically refreshes SSA-managed shipping templates to reflect current shipping-service delivery capability; sellers who are not comfortable with a recommended transit time can switch back to manual templates
- SSA is one of the tools tied to other seller-fulfilled protections and requirements — it is part of the Automated Handling Time + SSA + Amazon Buy Shipping combination Amazon points to for OTDR protection and for meeting the Business Hour Delivery Rate requirement
What You Should Do Now
- 1Open Settings > Shipping Settings in Seller Central and check whether Shipping Settings Automation is enabled on your shipping templates
- 2If you previously maintained a shipping service priority list for SSA, confirm it is no longer required and review the transit times Amazon is now applying
- 3Compare the delivery dates now displayed on your seller-fulfilled offers against what you were promising before, and sanity-check a few destination ZIP codes
- 4If a recommended transit time looks wrong for your operation, switch that template back to manual rather than absorbing late-delivery risk
- 5Pair SSA with Automated Handling Time and Amazon Buy Shipping ahead of the September 30, 2026 Business Hour Delivery Rate requirement and Q4 peak
