Mercari tracking FAQ

What shipping carriers does Mercari use?
Mercari US offers prepaid shipping labels for USPS Ground Advantage, USPS Priority Mail, UPS Ground, UPS SurePost, and FedEx Ground Economy/Home Delivery. Mercari Japan orders ship via Yamato Transport (Kuroneko), Japan Post (EMS / Registered Airmail), and DHL/FedEx.
Why is my Mercari UPS SurePost package taking longer to update after Drop-Off?
When a seller drops off a Mercari UPS SurePost label at a UPS Store or Access Point, UPS transports the parcel to the destination city before either delivering it directly or transferring it to USPS for final mailbox delivery.
How do I track a Mercari Japan item after it leaves Tokyo?
Mercari Japan parcels shipped via Japan Post EMS (EN...JP) or Registered Airmail log a Dispatch from outward office of exchange scan in Tokyo/Osaka, clear US ISC customs, and can be tracked with the same 13-character S10 barcode on both Japan Post and USPS.
