Poshmark tracking FAQ

What shipping carriers does Poshmark use?
In the United States, Poshmark prepaid labels (PoshPost) ship exclusively via USPS Priority Mail and USPS Ground Advantage. In Canada, Poshmark orders ship via Canada Post Expedited Parcel and Purolator Ground.
Why does my Poshmark tracking say Pending USPS Scan after the seller marked it shipped?
Sellers often drop Poshmark packages in collection boxes or self-service kiosks after hours. Tracking updates from 'Pending USPS Scan' to 'In Transit' as soon as the parcel reaches the regional USPS origin distribution center.
How does tracking work on Posh Authenticate orders over $500?
Items priced at $500 or more first ship from the seller to Poshmark headquarters for physical authentication, and once verified, a second USPS Priority Mail tracking number is issued to your doorstep.
