eBay warns sellers of USPS rate hikes effective September 19, 2026 with one day's notice
eBay announced on September 18, 2026 that USPS shipping rates available through eBay Labels will increase effective September 19, 2026, giving sellers just one day's notice. Ground Advantage rates will rise $0.10 for packages weighing 0‑2 pounds and from $0.27 to $2.28 for 3‑5‑pound parcels across Zones 1‑8, while Priority Mail flat‑rate packages will go up $0.30 for the same zones.
The adjustments do not apply to rural ZIP Codes, which keep a separate USPS rate structure that has been in place since 2024. eBay’s shipping calculator will automatically update to reflect the new rates when they take effect on September 19. USPS temporary peak‑season pricing is scheduled to start October 4 and run through January 17, adding another round of changes shortly after the September update. eBay reported double‑digit year‑over‑year growth in shipping revenue for Q2 2026 and cited shipping, advertising and payments as positive contributors to its take rate.
eBay sellers have been dealing with frequent USPS rate changes since a surprise discount in June lowered Ground Advantage costs for 3‑5‑pound shipments. That was followed by revisions to ounce‑based tier pricing for Ground Advantage, the regular annual USPS rate update in July, and several adjustments to specific weights and zones throughout August. USPS temporary peak‑season pricing is set to begin October 4 and run through January 17, meaning another rate shift is due just over two weeks after the September 19 update.
