A supplier’s address can sound like a simple detail. Before you place an order, it is a question worth slowing down for.
You need to know which address belongs to the legal entity, which address is the supplier’s office, and which location is actually involved in making your product. Those can be the same place. They can also be different places for ordinary business reasons. A difference is not proof of a problem. It is a prompt to document the relationship and ask better questions.
Factory-address verification is not about finding a pin on a map and declaring the supplier approved. It is about connecting a real operational site to the product, process, and legal entity you are considering. The stronger the evidence you need, the more the review should move beyond online information toward direct, risk-appropriate verification.
Separate the three addresses from the start
Create separate fields in your supplier file for the following locations:
| Address type | What it means | What it can tell you |
|---|---|---|
| Registered address | The legal entity’s registered address | Helps identify the company behind the relationship; it may be an office rather than a factory. |
| Office or sales address | The place where commercial staff work or receive mail | Helps explain where the relationship is managed; it does not prove production capability. |
| Production address | The site or sites where the product is manufactured, assembled, packed, or otherwise handled | Relevant to capability, quality-control planning, and a possible site review. |
Ask the supplier to provide each address in Chinese and English where possible, along with the role of the location. If several sites are involved, ask which process occurs at each one. For example, one site may mould plastic parts, another may assemble the product, and a third may package or warehouse finished goods.
Do not assume that the address shown on the business license is the production site. Article 11, How to Read a Chinese Business License Before You Pay a Deposit, explains why a registered address is part of an entity check, not factory proof.
Define what you need to verify
The right question is not always “Is this a factory?” A better question is: “Which site performs the work that matters for my order, and what evidence supports that answer?”
Start with your product and order profile. If you are buying a standard item with a low-value sample order, you may only need a basic location record, clear product information, and a transparent explanation of the supplier’s role. If you are funding custom tooling, ordering a safety-sensitive product, or committing to a large first production run, your need for location and capability evidence is much higher.
Write down the processes that matter to the order. Depending on the product, that may include component production, moulding, machining, sewing, assembly, finishing, printing, testing, packing, or warehousing. Then ask the supplier where each process occurs and whether it is controlled by the same legal entity.
This shifts the discussion away from labels. A company may be a legitimate trading company, manufacturer, or group entity. What matters for your sourcing decision is knowing who controls each part of the work and what you can verify before you pay.
Ask for a production-site declaration
A short written declaration is more useful than a vague claim that the company has “its own factory.” Ask the supplier to state:
- The full production-site address in Chinese and English;
- The legal entity or entities operating at that address;
- Which product processes are performed there;
- Which processes, if any, are subcontracted and to whom;
- Whether the site makes your product directly, makes components, assembles it, or only stores it;
- The name and role of the person who can answer facility and process questions;
- Whether a video call, visit, or independent audit can be arranged if the order requires it.
These questions do not accuse the supplier of anything. They set a clear evidence standard. A capable supplier should be able to explain its role in the supply chain even when part of the work is done elsewhere.
Save the response beside the address in your supplier file. Later, if the supplier changes the production location, you can compare the new explanation with what it originally told you.
Compare address information across documents
An address is more useful when it appears consistently in documents that serve different purposes. Compare the company’s statement with the business license, registry information where available, website, product documents, quotations, invoices, and shipping records relevant to the transaction.
Do not expect every document to show the same address. A registered office, factory, and warehouse may all be legitimate locations. The comparison is designed to reveal questions, not force a false match.
| Source | Address to record | Question to ask if it differs |
|---|---|---|
| Business license | Registered legal-entity address | Is this office also a production site? If not, which entity operates the factory? |
| Supplier quotation or contract | Seller’s address and contract party | Does the contract identify the legal entity responsible for production or supply? |
| Website or catalogue | Listed office, showroom, or factory address | Which location applies to the product being quoted? |
| Video-call invitation or site-tour record | Claimed production-site address | Does the view match the process and address the supplier declared? |
| Audit or inspection report | Site visited and entity reviewed | Does the report identify the actual site and the scope it covered? |
| Shipping or packing records | Origin or warehouse location, where relevant | Is this production, consolidation, or warehouse activity? |
A mismatch may be explainable. A supplier may use a warehouse near a port, rent a separate office, or work across multiple sites. Ask for the explanation in writing and decide whether it is sufficient for your order risk.
Use remote evidence as a screening tool
Remote evidence can help you decide which suppliers deserve a deeper review. It is not the same as independently confirming a factory site.
A map search can show whether an address appears to be in a commercial, industrial, or residential setting. A company website can show how the supplier presents its locations. A live video call can allow you to ask the person on site to show a production line, equipment, material, work-in-process, quality area, and site entrance. Time-stamped photographs can document specific views.
Each item has limits. A map image may be old or ambiguous. A website can be copied or out of date. A video tour can show a real facility without proving that the supplier controls it, that it makes your product, or that the view represents current production conditions. Use remote material to generate questions and identify inconsistencies; do not let it substitute for evidence when your risk calls for more.
Ask for a live, unscripted walkthrough only when it is appropriate for the stage of the relationship. Give the supplier a short list of areas relevant to your product, rather than demanding access to sensitive areas or unrelated customer work. Record the date, participants, stated site address, and questions that remain unanswered.
Look for evidence related to your product process
The most valuable site evidence is not a large building in the background. It is evidence that the location can perform the work your product requires.
China Briefing describes operational supplier review as an examination of production facilities and whether what a supplier claims is accurate in practice. Examples it gives include facility size, production capability, machinery and operational status, material handling, inspection equipment, and personnel at each production step. [1]
Use that framework to ask product-specific questions. For a sewn bag, look for relevant cutting, sewing, inspection, and packing controls. For an injection-moulded product, ask which location has the moulding machines, where tooling is stored, and how parts move into assembly. For a product with electrical components, distinguish the final-assembly site from the component or PCB supplier if they are different operations.
You are not trying to carry out a full technical audit from a single call. You are testing whether the supplier’s address claim, process explanation, and visible evidence make sense together.
Know when a site review is the better next step
When address and capability evidence affects a material order decision, consider a factory visit or an independent manufacturing audit. This is particularly relevant for a new supplier, a complex product, a custom project, a high-value deposit, or a supplier that cannot explain multiple locations clearly.
QIMA describes manufacturing audits as on-site evaluations of a supplier’s factory, capability, quality systems, and workflows, often used before an order. Its standard audit scope includes the factory profile, production capacity, facilities and machinery, workflow, organization, and quality-assurance systems. [2]
An audit should have a clear scope. Tell the auditor which product category, process, legal entity, and specific address matter to your order. Ask the report to identify the site visited, the date of the visit, the entity being reviewed, and any limitations. An audit of one location does not automatically cover every subcontractor, warehouse, or related company in the product’s supply chain.
For some orders, an independent visit may not be proportionate. That does not mean you should skip all location work. It means you should document the evidence you have, the questions you asked, and the risks you chose to accept at that stage.
Do not use the address as a shortcut for supplier type
It is tempting to make simple rules: an industrial address means factory; an urban office means trading company; a different address means a problem. Real supply chains are not that neat.
A manufacturer can have a sales office in one city and a factory in another. A trading company can be a suitable partner when it is transparent about its role, product sources, and responsibilities. A group can have separate entities for production, sales, and export. A factory can use external finishing, testing, or packaging sites.
Address verification should clarify the structure. It should not be used to force an inaccurate label. The goal is to know which organization and site will be responsible for the work you are paying for, and which parts of the production path still need evidence.
Record questions and decision points
Create a short address-verification record for each serious supplier. Include the legal entity, registered address, claimed production address, process at each location, evidence reviewed, unanswered questions, and required next step.
| Item | Example record |
|---|---|
| Legal entity | Exact Chinese name and unified social credit code from the entity review |
| Registered address | Record as shown on the license or registry result |
| Claimed production site | Full address, site contact, and process carried out there |
| Evidence reviewed | Supplier declaration, video call date, product photos, audit report, or other record |
| Process match | Which relevant production steps were evidenced and which remain unconfirmed |
| Open questions | Ownership or control of site, subcontracting, machinery, capacity, inspection, or warehouse role |
| Next step | Clarification request, sample review, site audit, hold, or remove from shortlist |
This record makes it easier to compare candidates fairly. It also makes it harder for an unanswered question to disappear once a supplier sends an attractive quotation.
Sourcing All’s guide to building a China supplier shortlist provides the earlier framework for documenting candidates before the address-review stage.
Pause when the story keeps changing
A changing address is not automatically a red flag. Factories move, add capacity, open a second site, or reorganize their operations. The concern is not change itself; it is unexplained change or an inability to connect the location with the work.
Pause and request clarification when a supplier will not provide a full production address, gives a different location each time you ask, cannot explain which entity operates the site, refuses to state where key production occurs, or asks you to pay before basic entity and site questions are answered.
The correct response is not to declare the supplier fraudulent. It is to avoid making a larger commitment until the evidence matches the order risk. You can hold the supplier on your shortlist, request specific documentation, or shift your attention to candidates that can provide a clearer production picture.
Treat address verification as one control in a wider decision
Factory-address work is strongest when it connects to the rest of your supplier review: the business-license check, the product specification, the sample process, the quotation scope, the quality plan, the payment path, and the agreement.
An address can confirm where to look. It cannot by itself confirm the product you will receive. A site visit can show equipment and processes. It cannot replace a detailed product brief or sample approval. A supplier can explain a multi-site structure. You still need to know which legal entity will accept the contractual obligation.
Verify the address with the level of evidence your order deserves. Keep the legal entity, office, and production sites separate in your records. Ask which location performs the work that matters. Then use direct evidence or an independent site review when the risk of being wrong is too high to leave the question open.
