Poshmark offers free item authentication and free shipping (limited time*) on all items $500 or more.

How does Posh Authenticate work?

When you purchase a luxury item valued at $500 or more, the order is authenticated directly through Poshmark HQ or via our trusted independent suppliers/resellers that source and pre-authenticate their items prior to shipment.

If an order is shipped to Poshmark HQ for authentication, our team of luxury experts carefully inspect the item’s authenticity by checking logos, tags, materials, hardware, quality, and more. Once we’ve confirmed authenticity, we’ll package it with care and ship it to you. If an item’s authenticity cannot be verified, we will refund you immediately.

Most pre-authenticated items are sourced and shipped directly from verified independent suppliers/resellers who have been carefully vetted by the Poshmark team. We stand by the authenticity of these items and the steps taken by the seller to ensure a safe, secure, and timely delivery to you.

Select pre-authenticated items will still be shipped to HQ for authentication, regardless of seller status, at Poshmark's discretion.
