USPS Regional Shipping Changes 

The USPS has restructured how it deals with local and regional shipping services. Along with these changes come some pricing changes. USPS Parcel Select Ground rates remain unchanged from 2022. However, local and regional rates have been impacted. 

2023 Changes to USPS Zones

The USPS has restructured its zones slightly for 2023. While Zones 1–9 will remain, the local zone is being discontinued. This historically has been for parcels that originate and are sent through the same post office. 

USPS Restructures Pricing for Zone 1 & 2

USPS is creating distinct pricing for both zones 1 and 2. Zone 1 shipments are shipments sent to recipients within 50 miles of the origin post office. Zone 2 shipments are sent within 150 miles. Historically, these two zones shared the same pricing structure. However, Zone 2 shipments will now see a slightly increased shipping rate over Zone 1 shipments.

USPS Discontinues Regional Rate Boxes 

Another change to regional shipments is that USPS no longer supports Regional Rate Boxes. These flat-rate parcels for shipments weighing up to 15 or 20 lbs will be phased out. While these services are no longer available, the remaining stock of Regional Rate boxes may be used as standard packaging until they deplete. Keep in mind, though, that these parcels will be charged the rate of the new, applied service. Economical replacements for Regional Rate Boxes may be USPS Parcel Select Ground or other discounted USPS services available through ShipEngine Carriers

USPS Simplifies Priority Shipments to Canada 

Historically, Priority Mail International shipping rates destined for Canada were segmented into 8 different Pricing Groups. USPS has now streamlined Canadian pricing into a single group for any and all Canadian delivery locations. All Priority Mail International shipments sent to Canada will now fall into International Pricing Group 1.
