The State of FBA Prep 2026.
We tracked, deduplicated, and adjudicated 715 distinct entities that present themselves as Amazon FBA prep services, an estimated 92% of the web-visible population (~777 by mark-recapture). 50% are actually 3PLs or fulfillment platforms wearing the prep label, and 21% are dead. 107 cleared our verification standard and are listed, each typed for what it actually is.
Most of the FBA prep market is not what it says it is.

How many Amazon FBA prep centers are there in 2026?
As of 2026-07-15, fbaprepfinder estimates roughly 777 web-visible entities worldwide present themselves as Amazon FBA prep services (mark-recapture estimate; 715 individually tracked, 85% US). Only 131 of the tracked entities look like genuine prep specialists: 72 verified and listed plus 59 candidates in vetting. 50% are general 3PLs or fulfillment platforms where prep is a side offering, and 21% are dead.
Every tracked entity, in exactly one bucket.
Buckets partition the 715 tracked entities and sum exactly. No survivor funnels: machine verdicts appear as counts only, and unclassifiable entities stay in their own bucket.
Prep-specialist candidates in vetting
59
Look like genuine prep specialists; awaiting verification or on dated holds (most commonly the 12-month operating minimum).
Rejected at verification
15
Presented as prep centers but failed human verification: fabricated tenure, recycled testimonials, cloned sites, unverifiable identity.
3PL or fulfillment platform wearing the prep label
356
General third-party logistics or multi-channel fulfillment where FBA prep is a sub-page, not the productized core.
Dead
148
Site unreachable or business defunct at last check. Dead is re-checked, not permanent; a July 2026 re-sweep found 13 previously dead sites back online.
Not yet classifiable
30
Too thin or ambiguous to classify with confidence. An honest bucket, never counted as classified out.
We type every listing for what it actually is.
As of July 2026, every listed operator carries an explicit type, because "prep center" turned out to be a label half the market borrows rather than a business model:
Prep specialist
72
Inbound FBA prep is the productized core: per-unit receiving, inspection, FNSKU labeling, polybagging, bundling, forwarding.
Multi-service
28
Prep-primary positioning with a real co-primary line: DTC or B2B fulfillment, contract packaging, sourcing, storage divisions. Disclosed on every profile.
Full 3PL
7
General fulfillment operations with a confirmed, substantive FBA prep service. Never ranked and never counted in specialist stats.
What stays pure: our ranked list and headline counts are prep-specialist territory. Directory inclusion is not ranking, and a paid tier never changes a type or a rank.
How we counted, and how we know what we missed.
Discovery. Entities enter the census from multi-modal sweeps: search queries in four languages, competitor directory mining, seller community mentions, and inbound applications. Every entity is deduplicated by domain before counting.
Classification. A machine first-pass proposes a label; every published, rejected, or held verdict is human adjudication against primary sources (state registries, Companies House, Impressum/VAT records, archived snapshots, third-party reviews). Machine labels alone never publish anything and appear here as counts only.
Coverage estimate (mark-recapture). On 2026-07-14, with 691 entities tracked, we ran three independent discovery agents that surfaced 136 candidates. Of those, 121 were already in our database, a 89% recapture rate. The Lincoln-Petersen estimator (691 x 136 / 121) puts the web-visible population at roughly 777. Operators with no web presence at all (cottage shops recruited inside seller communities) are invisible to this method and not counted.
Churn. Dead is a timestamped observation, not a tombstone: sites are re-swept, and recovered operators re-enter vetting. Published listings are re-verified on an ongoing cadence and flagged visibly when checks fail.
The named integrity exclusions (fabricated tenure, AI-generated storefronts, recycled testimonials) are published with reasons in our verification study. The full census dataset is downloadable as JSON under CC BY 4.0.
