Do I need an Amazon prep center in 2026?

Yes, most FBA sellers now need a prep center. Amazon discontinued its in-house FBA prep and labeling services on January 1, 2026, so every unit must arrive fully labeled, poly-bagged, and compliant. A third-party prep center applies FNSKU labels, packages to Amazon’s specs, and ships to fulfillment centers, helping you avoid inbound defect fees.
