How we verify FBA prep centers.

This page explains how we keep listings fresh for buyers. Every published prep center has passed five checks within the last 30 days. If a listing's most recent check falls outside that window, it shows a stale badge until we re-verify. If a check fails, the listing is flagged with the failure reason visible on the profile page.

The 5 checks

Every listing clears all five, or it doesn't get published.

  1. 01

    Business operating > 12 months

    State business registry confirms the legal entity. LinkedIn-confirmed founders. First public listing on prepcenter.com or amzprep.com no later than 12 months prior to our verification date — we want a track record, not a one-month-old shop fishing for inbound leads.

  2. 02

    Phone answered live within 2 rings

    A real person, during stated business hours, on the listed phone number. Voicemail counts as a fail. Three consecutive call-fails archives the listing. We log the call timestamp and the name of the person who answered.

  3. 03

    FDA registration confirmed via fda.gov

    Only required for centers that claim FDA registration (mandatory for supplements). We cross-check the registration number against the FDA establishment database. Unverifiable claim = listing flagged or excluded, depending on the rest of the profile.

  4. 04

    Website returns 200 + matches Amazon FBA keywords

    The domain resolves. HTTP 200 from / and at least one contact page. The site prominently mentions Amazon FBA, FNSKU, prep services, or 3PL — we don't accept centers that bury their FBA capabilities behind a contact form.

  5. 05

    Manual editor review every 30 days

    A human re-reads the listing, cross-checks the center's name against Amazon-seller forums, Reddit r/FulfillmentByAmazon complaints, and BBB. We re-confirm pricing notes and update retrieval dates. At the first credible red flag, the listing is flipped to flagged.

How exclusions work

We name names — including listings we've removed.

When we exclude a center, we don't quietly drop it. The exclusion is logged on our top-list page with the date and reason. We preserve the archived URL so the page doesn't 404 — anyone who linked to or bookmarked the listing still lands on a page explaining what happened.

The most common exclusion reasons we've seen: phone unanswered on three consecutive checks, domain expired without renewal, claimed FDA registration not verifiable, or persistent seller-forum complaints we couldn't resolve via the center's stated process.

Editorial guarantees

What you can expect.

  • Labeled featured listings. Rankings on our top-list are editorial. If we add a featured slot in the future, it will be clearly labeled on the entry itself and at the top of the page — never mixed in with editorial picks.
  • No fake ratings. Our LocalBusiness JSON-LD never includes aggregateRating unless real reviews exist. We won't pad SERP rich results with fabricated star scores.
  • Verification stays verification. The 5-check battery above is run on every published listing regardless of featured or sponsor status. Failures are visible on the profile.
  • No tax advice. Pages about tax-free states explain mechanics. They do not substitute for a CPA.
