At a glance

Average EasyPost label cost broken out by shipping zone (the distance band between your despatch origin and the destination) over the trailing 30 days. Carrier pricing is zone-based, so this horizontal bar chart shows where your parcels are expensive: a heavy tail in the far zones points at distant customers, a missing warehouse, or a rate-shop rule that is not picking the cheapest carrier for that lane.

​
What it tracks

Grounded in the card’s detail (“Cost by Zone.”): the card reads the bought rate on every EasyPost shipment (GET /v2/shipments, the selected_rate plus surcharges and the per-label fee) and groups it by the zone derived from origin and destination postcodes. For US carriers this is the USPS / UPS / FedEx zone (Zone 1 nearby through Zone 8 furthest); for international it groups by destination region. Each bar is the average cost per parcel in that zone over the 30-day window, so a longer bar means a more expensive lane, not necessarily more volume. Read it next to Shipments by Destination to weight cost by where your parcels actually go, and next to Avg Shipping Cost for the blended headline. A persistent far-zone cost bulge is the classic signal to evaluate a second despatch location or a regional carrier for that band. This card carries no alert; it is a diagnostic surface, not a pager.

​
Reconciling against the source

Cross-check against the EasyPost dashboard billing view (filter shipments by date and group by zone) and against each underlying carrier’s own zone-rate chart in the carrier portal. Small differences come from surcharge timing and the EasyPost per-label fee; large gaps usually mean a rate-shop rule is overriding the cheapest carrier for that zone. For a like-for-like comparison against direct carrier contracts see Cost per Parcel by Zone vs Direct-Carrier Pricing.
