A carrier adjustment is an additional charge or credit that is applied when a shipment’s actual details differ from what was entered when booking. 


Carriers verify shipment information during transit, and adjustments are calculated by the carrier. These adjustments occur regardless of where or when shipping is purchased. 


Common reasons adjustments occur:

  • Dimensions or weight differ from those originally entered.

  • Package dropped off from a different address.

  • Address required correction prior to delivery.

  • Dimensions or weight exceed the maximum allowed.
