Universe coverage · Updated continuously

The whole universe, the working pipeline, and the receipts.

We map the universe of US Amazon FBA prep centers from public sources and classify each one. The counters below are live: total mapped, verified and listed, classified out (3PL hybrids and closed businesses), and the ones we cannot classify with confidence yet. Every verified center cleared our 4-point operator standard before listing.

Our coverage of the prep-center universe

Mapping 677 prep centers.

We map the universe of Amazon FBA prep centers from public sources and classify each one. Most are general 3PLs or fulfillment platforms; some look like pure prep and are eligible for verification; some we cannot classify with confidence yet. Only centers that independently clear our 4-point operator standard are listed. We list what we verify, not what we scrape.

All verified centers

Every verified center, A-Z

All 65 published prep centers we have verified, linked directly. Each cleared our 4-point operator standard.

How we add new centers.

  1. Source. Public business directories, operator websites, Google Places (via the official Places API), referrals from sellers in the match form. We do not buy lead lists.
  2. Pure-FBA-prep classifier. We exclude operators positioned as multi-channel 3PLs (FBM, DTC, Shopify, Walmart, WFS as primary services). Those route to our 3PL recommendations instead.
  3. 4-point operator standard. Pricing transparency, turnaround SLA, capacity claim, seller-central integration, hazmat/FDA capability where relevant. See the methodology for the full scorecard.
  4. Listing. Cleared centers move to published. Pending centers stay in queue with a visible counter above; nothing thin gets shipped to make the directory look bigger.

On the list and want off?

We list businesses by name only after they clear verification and become published. Pending and excluded entries are tracked privately and never appear by name on public pages.

If you are a published operator and want to be removed, email hello@fbaprepfinder.com from a domain that matches your listing, or sign in to your operator dashboard and use the "Request removal" flow. We honor verified removal requests within 48 hours.

The moat narrative, in plain English.

Prep-center directories go stale because operators close mid-shipment and most directories don't notice. Ours has a automated liveness check, shows staleness rather than hiding it, and keeps a visible exclusion list. We re-verify on user reports and maintain a public pipeline so what we know about the universe is auditable.
