Can I track a eBay order without a tracking number?

In most cases, you cannot track an eBay order without a tracking number, but you can still see limited shipment details.

Buyers can view the estimated delivery date, shipping service, and seller’s dispatch confirmation under My eBay → Purchase History.

If no tracking number was provided, it usually means the seller shipped with an untracked service (common for low-cost or international items).
To track the shipment properly, you must request the tracking number from the seller.
