Asking a supplier for client references is Sourcing 101. But what happens when the references themselves are fake? A growing number of fraudulent suppliers have moved beyond fake product photos — they now fabricate entire client relationships. Here are seven investigation techniques to separate real references from invented ones, based on patterns we've observed across hundreds of supplier audits.
Before we get into detection techniques, understand what you're looking for. Fake references typically fall into one of four patterns:
The supplier gives you the contact of a real business — owned by their cousin, former classmate, or business partner. The reference will give a glowing review because they have a personal relationship with the supplier, not because the supplier actually delivered for them.
The supplier registers a simple LLC in the US or UK, creates a basic website, and uses it as a "satisfied client." When you call, you're talking to the same person who runs the supplier's sales operation — using a different name and accent. The shell company has no real business activity.
The reference is a real buyer who did one small order three years ago. The supplier continues to use them as a reference long after the relationship ended — and the reference doesn't even know they're being used. When called, they might say "Yeah, we bought from them once" — which isn't a lie, but it's also not a meaningful endorsement.
In the most sophisticated cases, the supplier pays someone — often a freelance English speaker on Fiverr or Upwork — to pose as a satisfied buyer during a reference call. They are given a script, a backstory, and product details. It's a small investment for the supplier to close a deal worth tens of thousands of dollars.
Don't just visit the website the supplier gives you. Search for the reference's company on LinkedIn, check their business registration in their home country, look for press mentions, and find their physical address. A real company leaves a trail. A shell company has a one-page website and nothing else. If the "company" has no employees on LinkedIn, no Google reviews, and no independent web presence outside the domain they gave you — it's probably not a real operating business.
A genuine buyer who has done business with a Chinese factory knows the factory's real Chinese name — because it appears on contracts, invoices, and shipping documents. Call the reference and ask: "What's the supplier's full Chinese company name?" If they hesitate, can't produce it, or give you a different name than what the supplier told you, you have caught a fake. This single question exposes more fake references than any other technique.
Instead of "How was your experience?", ask: "What was the SKU number of the product you ordered?" or "What was the PO number on your last shipment?" A real buyer can pull this up. A fake reference will say "I'd need to check my records" — and then never produce the information.
Ask the reference if they'd be willing to share a redacted bill of lading or shipping invoice from their last order with the supplier. Explain that you want to confirm shipping timelines. A real buyer may or may not share it (some consider it confidential), but they'll at least engage with the request. A fake reference will get defensive, change the subject, or disappear entirely.
Cross-reference dates. If the reference claims they've been buying from the supplier "since 2018," but the supplier's business license shows the company was established in 2020 — someone is lying. Similarly, if the reference mentions product categories the supplier's business scope doesn't cover, that's a discrepancy worth investigating.
If a supplier gives you three references, call all three and compare their answers. Do they use the same unusual phrases? Do they describe the supplier's strengths in identical language? Do they all mention the same "minor issue that was quickly resolved"? Scripted references often share a script. Real buyers describe different experiences with different words.
Commercial import/export databases like Panjiva, ImportGenius, and Descartes Datamyne track US customs records. Search for shipments from the supplier's name to the reference's company name. If the reference claims to have done "multiple containers per quarter" but there's zero customs record of shipments between those entities, the relationship may not exist. Note: this works for US-bound shipments; EU and other destinations may require different databases.
A single fake reference should kill the deal — period. Do not give the supplier a chance to explain. Do not accept "I gave you the wrong contact by mistake." A supplier willing to fabricate client references is willing to fabricate anything: certifications, production capacity, product specifications, and shipping documents. Walk away. There are tens of thousands of legitimate suppliers in China. You don't need to gamble on one who has already been caught lying.
References — even real ones — are a limited signal. A supplier can give you their three happiest clients and hide the ten who had a terrible experience. Independent verification doesn't rely on curated information from the supplier. It pulls from government databases, legal records, and on-the-ground inspection — sources the supplier cannot control or filter. If you're placing an order large enough that you're asking for references, you should also be verifying the supplier independently. References tell you what the supplier wants you to hear. Verification tells you what the supplier might not want you to know.
Our Safety Shield report cross-references government databases, legal records, and business registration details to confirm who you're really dealing with — no supplier-provided information required. Combine it with a Reality View factory visit for a complete picture.
