In today’s global supply chain, verifying suppliers isn’t just a smart move, it’s essential. Whether you’re sourcing raw materials, finished goods, or components, one wrong decision can cost your business time, money, and trust.
Working with unverified suppliers comes with serious risks: counterfeit goods, late shipments, poor product quality, or worse, being ghosted after a payment. For small and midsize businesses, even one bad transaction can be a major setback.
This guide shows you how to verify suppliers effectively, and how VALO Vietnam helps buyers connect only with trusted partners in Vietnam, so you can skip the uncertainty and get straight to business.
Step-by-Step: How You Can Verify a Supplier Yourself
1. Check Business Registration & Licenses
Before placing an order or even negotiating, make sure the company is legally registered. Every legitimate supplier should be able to provide their business license and tax registration.
How to do a company registration lookup:
- In Vietnam, you can search the National Business Registration Portal to confirm company status.
- Look for the business name, registration number, legal representative, and business scope.
A valid license should:
- Match the supplier’s name and address
- Be current (not expired or recently changed ownership)
- Show authorized business activities related to your product
If the documents feel off, don’t proceed, it’s a red flag.
2. Run a Supplier Background Check
Once you confirm the license, the next step in how to verify suppliers is to dig deeper into their history and reputation.
How to run a background check:
- Google the company name along with words like “scam”, “fraud”, or “review”.
- Check platforms like Trustpilot, Alibaba reviews (if applicable), or regional forums.
- Look for any patterns: complaints, delivery delays, or lawsuits.
Also, scan blacklist databases or ask trade associations if the supplier has been flagged.
3. Ask for References and Past Clients
A credible supplier won’t hesitate to give references. If they dodge the request or say “We can’t share due to confidentiality,” proceed with caution. This is an important step in how to check verified suppliers, as authentic references help confirm the supplier’s reliability and history.
What to ask:
- Which companies have you worked with in the past 12 months?
- Can I contact a recent buyer?
- Have you done similar products before?
Then, verify those references. A quick email or call can reveal a lot, including if the supplier delivered what they promised.
4. Evaluate Certifications and Compliance
Certifications matter, but only if they’re real and up to date.
Ask for certifications like:
- ISO 9001 for quality management
- CE/ROHS for electronics
- GMP or HACCP for food or health-related products
Then, verify them. Contact the issuing body or check online databases to make sure the certificates are legitimate, not Photoshop fakes.
5. Conduct a Factory Visit or Use Third-Party Inspections
Seeing is believing. If possible, visit the factory yourself, especially if the order is large or high-risk.
What to inspect:
- Factory size and real capabilities (do they match what they claim?)
- Machinery and worker conditions
- Packaging and quality control process
If you can’t go in person, hire a third-party inspection company to visit and report.
6. Analyze Financial Stability
You want a supplier who can deliver today and still be around tomorrow, that’s why knowing how to verify suppliers is so important.
How to assess:
- Ask for bank references or credit reports (especially for long-term partners).
- Check how long they’ve been in business and whether they’ve had payment issues.
A financially unstable supplier might take your deposit, then go bankrupt or disappear. Don’t gamble with your supply chain.
7. Use Online Tools and Databases
There are tools that make supplier verification easier and faster.
Try:
- Alibaba’s Verified Supplier badge
- Vietnam Chamber of Commerce & Industry (VCCI)
- VALO Vietnam’s own verified supplier listings
These platforms often include company registration, product range, past performance, and inspection reports, saving you hours of manual checking.
How VALO Vietnam Verifies and Approves Trusted Suppliers
Choosing the right supplier can make or break a deal, but verifying one from another country? That’s a minefield. At VALO Vietnam, we don’t just connect buyers with suppliers. We carefully curate trusted partnerships through how VALO verifies suppliers, a multi-step process that weeds out unreliable players before they even reach our platform.
VALO’s Supplier Verification Process
Every supplier listed on VALO Vietnam goes through a rigorous screening process designed to protect buyers from fraud, delays, and poor quality.
Here’s how we do it:
- Business License Verification
We confirm the supplier’s registration through official government databases. No valid license? No listing. - Background Checks
We dig into the supplier’s reputation, including legal disputes, online feedback, and known affiliations. - Document and Compliance Review
We check for key certifications (like ISO, CE, GMP) and validate that documents are not fake or expired. - Sample and Product Validation (when applicable)
In select cases, we work with buyers or inspectors to confirm product quality before the first major order. - Communication and Responsiveness Evaluation
We monitor how the supplier handles communication. Vague answers, slow replies, or evasive behavior? That’s a hard no.
What Makes a Supplier VALO-Approved?
We don’t list just anyone. Suppliers must meet clear, non-negotiable criteria to be considered pre-screened. This is how we ensure you can confidently verify suppliers on VALO Vietnam, knowing they meet high standards for reliability, transparency, and quality.
- Legitimate documentation: licenses, tax ID, ownership info
- Operational capacity: proven ability to handle volume and quality standards
- Verified product range: we confirm they can actually supply what they claim
- Positive buyer feedback: we look for patterns of consistency, transparency, and satisfaction
- Willingness to comply with third-party checks: honesty and openness are key
What This Means for You as a Buyer
When you source through VALO, you’re not going in blind. You’re partnering with pre-vetted, credible suppliers who are ready to deliver, no shady surprises, no guesswork.
This means:
- Peace of mind: every supplier has passed multiple layers of checks
- Secure sourcing: fewer risks of fraud or non-performance

Common Red Flags in Supplier Verification
No matter how convincing a supplier may seem, certain behaviors should immediately raise concern. Whether you’re learning how to verify suppliers on your own or working with a sourcing partner, watch for these red flags:
- Vague or incomplete answers to basic questions about licensing, clients, or capabilities
- Unverifiable certifications or missing compliance documents
- Pushy sales tactics rushing you to place orders or make fast payments
- Use of personal bank accounts for payments (always a bad sign)
- Refusal to allow third-party inspections or audits
- Inconsistent product samples, especially if they differ from catalog claims
If you notice one of these signs, dig deeper or walk away.
Why Supplier Verification Is Not a One-Time Task
Verifying a supplier isn’t just something you do before the first deal, it’s a process that should continue throughout your partnership.
Things can change quickly:
- A factory may change ownership
- Compliance certifications might expire
- Financial troubles can hit even previously reliable suppliers

- Rechecking registration status and documents
- Collecting and reviewing buyer feedback
- Updating supplier profiles when changes occur
- Facilitating post-deal reporting and dispute resolution, if needed
This means you’re not just protected before a deal, you’re supported throughout the relationship.
