What is the estimated transportation time?
Estimated transportation time is generally 3–7 business days after dispatch.

Does the 3–7 business day period include preparation?
No.
Preparation takes place before dispatch.
The transportation estimate refers specifically to the period after the parcel has been dispatched.

Transportation may be affected by destination, carrier conditions, public holidays, severe weather, regional disruption, customs procedures where applicable, incorrect recipient information, or other circumstances outside reasonable operational control.
When should tracking information appear?

Carrier systems may require additional time before displaying their first tracking event.

What if tracking says delivered but I cannot find the parcel?

-
Household members;

Reception desk;
-
Building management;
-
Parcel locker;

Carrier notices;

Other reasonable secure delivery locations.
