A proforma invoice says "factory." The physical reality can be a three-bedroom condo. Buyers get a polished invoice, a wire request for tens of thousands of dollars, and an address that turns out to be an apartment or a shared desk in a downtown office tower. Digital storefronts are cheap. Real production lines are expensive. Most buyers learn the difference too late, after they've paid a middleman markup to someone working from a kitchen table.
This is how to verify a Chinese factory address before you click send: read the business license against GSXT, run digital reconnaissance on Baidu Maps the right way, spot faked photos, and (the only step that fully settles it) send someone to the building.
Why a website address is not a factory location
A website showing 50,000 square feet of clean rooms, with a "Contact Us" address in a city's financial district, can resolve to a gleaming glass tower with a kid and a laptop in a shared office. That's the virtual-office trap, built to make a small trading operation look like a manufacturing titan. The English website is usually the first lie you'll meet; it's built for your eyes, not for the truth. The real story is in the Chinese business registration.
Registered office vs. production site. Chinese law lets a company register its domicile in one place and run assembly lines elsewhere, and trading companies exploit this: a prestigious office address to look bigger than they are. If the address ends in a room number on the 40th floor of a commercial skyscraper, that's a middleman, not a factory. Real manufacturers sit in industrial parks and manufacturing zones. A Supplier Reality Check™ bridges the gap between the address on paper and the machines on site.
On the "Verified" badge. A Gold Supplier badge is a paid marketing feature, not a technical audit. Traders have rented a corner of a legitimate factory for a single afternoon, hung a banner, filmed the "staff," passed a basic video inspection, then vanished. They have no control over quality or lead times. A digital badge is not verification; eyes on site are.
Step 1: deconstruct the business license (营业执照)
Never accept a photo of a computer screen or a low-res thumbnail. A slightly blurred patch around the address is a digital hack job. Demand a high-resolution scan of the original. Hesitation there usually means they're hiding a mismatch between their legal registration and their marketing claims.
Then read three fields:
Domicile (住所): the legal anchor of the company. Cross-reference it with the 18-digit Unified Social Credit Code (USCC), the company's DNA. If the address on the proforma invoice doesn't match the domicile exactly, stop. A common scam uses a real factory's license but swaps in the scammer's own bank details and a different "office" address on the invoice, to intercept your wire.
Business Scope (经营范围): look for "manufacturing" (制造). If the scope only lists sales, consulting, or import/export, you're dealing with a trader who doesn't own the machines and doesn't control the line.
Legal Representative: must be the same person signing your bilingual OEM agreement. If the names don't match, the contract may be worthless.
Verify on GSXT. The official source of truth is the National Enterprise Credit Information Publicity System at gsxt.gov.cn, a Chinese-only interface where the government tracks every legal change, including whether a company has been flagged for "abnormal operations." If it shows a residential address for a supposed industrial manufacturer, walk away.
Match address to bank account. A factory's location should align with its corporate bank branch. Manufacturer in Ningbo but the account is in another province, or a "virtual" branch offshore? Big red flag: money should stay in the jurisdiction where the goods are made. For complex cases, Due Diligence bridges paper records and physical reality.
Step 2: digital reconnaissance with Baidu Maps
Close the Google Maps tab. Google is blocked in China and its data here is years stale; you'll see empty fields where factories now stand. Use Baidu Maps (百度地图) instead.
Take the Chinese address string from the license, not the English translation, and paste the characters into Baidu. If the pin drops in a lake or a mountainside, the address is likely fake. If it lands on a building, switch to street view and look for the factory name in large Chinese characters on the exterior. If the sign on the gate doesn't match the name on your contract, you're probably dealing with a subcontractor or a trader pretending to own the factory.
Read the surroundings. A real factory needs infrastructure: loading docks, freight elevators, wide roads for container trucks, a power substation nearby. If street view shows a shopping district or a residential neighborhood, that's not a production line. Factories don't run on the 20th floor of a glass tower.
Check the satellite footprint. Suppliers love to claim a "50,000 square meter facility." Use Baidu's measurement tools on the roof. If the building is 2,000 square meters, they've inflated their scale 25x. Look at the roofline: one continuous building, or a multi-tenant block shared by ten small workshops? Check for recent construction too. Some "factories" on marketplace listing sites are demolished lots or empty fields.
Step 3: the smoke and mirrors of fake photos
A "live" walkthrough video can be a loop: a recording playing while they pretend to walk the line. (A three-year-old calendar on the wall is how these get caught.) The same 200-ton injection molding machine shows up in the brochures of five different companies across three provinces, all having stolen the same image from a defunct manufacturer.
Inspect signage in their photos. Zoom in. If the edges of the Chinese characters are too sharp against the building's texture, it's a digital overlay. Real signs are weathered and cast sensible shadows; a fake sign is just a layer in a photo editor.
Watch for the "borrowed factory." A trader walks you through a real factory, greets the workers, points at stock, but he's a middleman with a good relationship with the real owner. He doesn't control the schedule or the quality, and the moment you pay he loses all leverage over that line. You think you're buying from the source; you're buying from a guy with a visitor badge.
Reverse image search every facility shot: TinEye or Google Lens. If the same workshop appears on five sites, run. Look for other agents' or competitors' watermarks they forgot to crop.
Ask for the specific photo. A real factory complies with a specific request in minutes: the original business license held up in front of the main gate, or a specific machine on the line next to a paper showing today's date and your name. A scammer makes excuses: "safety regulations," "proprietary secrets," "the boss is away." Those excuses are the only red flag you need. When a supplier starts stalling, our Fixer service gets the ground truth.
The final verdict: a physical visit
A facility can pass every digital test (valid license, accurate Baidu pin) and still be a dead operation: cold machines, an inch of dust on the line, a "production manager" who's a cousin hired for the day, no output in six months, just waiting for a deposit to pay off old debts. Paper records tell you what the government thinks happened last year. They don't tell you what's happening on the line today.
A physical visit is the only way to confirm a factory isn't borrowing a neighbor's space. Suppliers have led buyers through a side door into an entirely different company's workshop. On site, you count the workers, look for subcontracting signs like boxes from other factories in the corner, and check raw-material inventory. If they claim they can start tomorrow but have zero materials in stock, they're planning to buy them with your deposit, and your lead time just doubled.
And never let an agent who takes factory commissions do your verification. His paycheck depends on you ordering, so he has every reason to overlook a dusty line or a missing business scope. Our fixed-fee model means the report is blunt because we don't care whether you buy. For Monthly Support clients, that visit runs every time a container loads. Or book a short call and we'll walk the address file before you wire.
What this looks like when the address is a lie
Two of our documented cases live exactly here. In one, a supplier's factory was registered in Shaoxing while every container quietly loaded in Xinjiang. The address said one thing, the shipping records said another, and it took a US customs detention to surface it: Case File #5. In another, the registered "factory" was a real building with production long since stopped, a few workers relabeling goods bought on the domestic wholesale market: Case File #2. In both, the paper looked fine. The site told the truth.
Secure your supply chain before the wire
A digital footprint is marketing. A paper record only shows what was legal on the day of registration. Verifying a factory address for real means an eyes-on-site approach that catches the staged workshops and borrowed production lines, the ones that pass every screen test.

Frequently Asked Questions
Can I verify a Chinese factory address for free? Yes. The government's official GSXT database (gsxt.gov.cn) is free. The catch is that the interface is entirely in Chinese and you need the company's exact Chinese name to get a result. Without the characters, you're guessing.
What is a Unified Social Credit Code? An 18-digit identifier that acts as a company's tax and legal ID. Every legitimate business has one, listed on the business license, linking the company to its legal representative and registered address. A supplier who won't provide it isn't a legal business.
Why does my supplier have two different addresses? One is the registered domicile, the other the production site, common and often legitimate. The risk starts when the two are in different provinces, which usually means your order is being subcontracted to a third party.
Is a business license enough to prove a factory is real? No. It proves a legal entity exists on paper, not that they own a single machine. Factories with perfect licenses have turned out to be empty warehouses. Paper is easy to doctor; physical production is not.
How do I know if a supplier is a trader or a manufacturer? Check the business scope for "manufacturing" (制造). If you only see wholesale, retail, or consulting, they're a trader: a markup and a layer of risk with no control over the line. Confirm it on-site.
What if the factory address is a residential building? Walk away. Factories don't run out of apartments. They need industrial power and loading docks. A residential registered address means a middleman working from home, pretending to be a factory to capture your deposit.
Does a Google Maps search work for Chinese factory addresses? No. Google is blocked in China and its data is stale. You'll see empty fields where factories now stand. Use Baidu Maps for a current street-level view.
