USPS Plans 2026 Holiday Price Increases: What Ecommerce Sellers Should Know

The United States Postal Service (USPS) plans to temporarily increase prices for several package services during the 2026 holiday shipping season. The changes are intended to help cover additional handling costs during peak demand.

Pending favorable review by the Postal Regulatory Commission, the increases would apply from October 4, 2026, through January 17, 2027. Priority Mail Express, Priority Mail, USPS Ground Advantage, and Parcel Select would be affected, while other USPS products and services would remain unchanged.

For ecommerce sellers, the impact will depend on package weight, shipping zone, and service. Commercial USPS Ground Advantage increases, for example, range from $0.40 for packages up to three pounds shipped within Zones 1-4 to $7.70 for packages weighing 26-70 pounds or oversized shipments to Zones 5-9. Priority Mail and Priority Mail Express would also see varying increases.

Ecommerce sellers can prepare by reviewing their expected holiday order profiles, comparing carrier rates, and checking whether current shipping charges and free-shipping thresholds still support their margins. Multi-carrier rate shopping can also help businesses select the most suitable service for each order as seasonal rates change.
