An address can validate as commercial in Shipstore but still get a FedEx residential-delivery surcharge. Shipstore's result is a local match. FedEx decides residential or commercial from its own records, so it can still charge residential.

Problem

Shipments get a FedEx residential-delivery surcharge even though the address validated as commercial in Shipstore (shown at 100%). FedEx may return "residential status unknown" for the address, and an address that validated commercial can turn out to be an apartment complex.

Cause

FedEx does not return a binding commercial-or-residential answer to the validation request. FedEx classifies each address on its own side as business, residential, mixed, or unknown, and it stays unknown until FedEx's data reclassifies it. Shipstore's commercial result is a local match only, so it does not stop FedEx from billing residential. FedEx can apply the surcharge from its own records or a driver's on-site flag, and FedEx says it cannot certify an address as 100% accurate.

What you can do

  1. Understand that the Shipstore validation result is a local match, not a FedEx billing guarantee. FedEx decides residential or commercial on its own side.
  2. Expect that FedEx may still bill a residential surcharge on an address that validated commercial, especially apartment or multi-tenant locations.
  3. Dispute a specific surcharge with FedEx when it is not correct, since the residential classification lives in FedEx's records, not in Shipstore.
  4. If you need tighter address matching, email support@shipstore.com to ask about optional custom logic that checks addresses against a CASS-certified USPS provider. This is optional and billable, it is not required to ship FedEx normally, and it still does not override FedEx's own classification.

What you should see

You understand why a locally commercial address can still be billed residential, and you know how to dispute a charge or ask about tighter matching.
