Woocommerce Usps Shipping Method - All Versions & Changelog

v5.6.0

LatestVerified Safe

Released June 30, 2026248.2 KB

Added

Optional shipping insurance and signature confirmation, offered to customers as selectable rates at checkout and priced by USPS.
New filters woocommerce_shipping_usps_skip_item_box_packing and woocommerce_shipping_usps_package_requests to let developers customise box packing and package requests.

Fixed

Service commitment delivery time shown in USPS rate labels is now scoped to the selected rate, fixing inconsistent visibility when a per-rate woocommerce_shipping_usps_should_show_service_commitment filter is used.
Round lbs-to-oz weight conversion in letter-rates requests to prevent USPS error 030004 on integer-oz boundary weights.

v5.5.4

File unavailableVerified Safe

Released April 14, 2026231.4 KB

Fixed

Correct large envelope (flat) classification to match USPS standards — items that exceed any (previously all) of letter dimension now qualify as flats.
