Summary
How to verify factory certification: locate the certificate number, search the certifying body’s public database (GOTS, OEKO-TEX, and most major schemes maintain one), confirm the validity dates haven’t lapsed, confirm the certified entity name matches the facility actually producing your goods, and confirm the scope covers your specific product category. A certificate can be entirely genuine and still not protect you if it’s expired, covers a different facility, or if part of your order is subcontracted to an uncertified site the paperwork never mentions.
The Logo Proves Almost Nothing

A supplier’s website shows a row of certification logos: GOTS, OEKO-TEX, and WRAP. Take your pick. It looks credible. It looks like due diligence has already been done for you, and most buyers stop right there, satisfied.
Here’s what almost no buyer knows: every one of those schemes maintains a public, searchable database, and almost none of them advertise it to buyers. The certifying bodies built the verification tool. They just never told you it existed, and neither did the supplier holding up the logo for entirely understandable reasons that have nothing to do with dishonesty and everything to do with incentives.
This matters because a logo, on its own, tells you nothing. It could be genuine and current. It could be genuine and expired eight months ago, quietly outliving its own validity while still sitting proudly on a homepage nobody’s updated. It could be entirely real, for the right company, at the wrong facility, issued to a sister factory three provinces away that has nothing to do with the building actually cutting and sewing your order. This guide is the fifteen-minute process that tells you which one you’re actually looking at, and we’re inviting you to run it on us specifically, because that’s the entire point of publishing it.
Why This Guide Doesn’t Exist Anywhere Else
There’s a structural reason nobody teaches this. Certifying bodies host the databases but have little incentive to market self-service verification tools to buyers; their paying customer is the supplier getting certified, not the brand checking up on them. And manufacturers, understandably, don’t publish guides encouraging their own customers to interrogate their paperwork.
That silence is exactly why doing the opposite works. A supplier confident enough to say “here’s how to check us” is telling you something no logo ever could.
The Fifteen-Minute Verification Workflow

Here’s the full process, in order. Run it once and it becomes second nature.
Step 1: Locate the Certificate Number
Every legitimate certificate carries a unique identifying number, a license number, a certificate number, or both, depending on the scheme. This should appear directly on the certificate itself and often on the product label alongside the logo. If a supplier can only show you the logo and not a specific number. Stop here; there’s nothing yet to verify.
Step 2: Find the Scheme’s Public Database
Each major certification scheme runs its own lookup tool:
- GOTS maintains a public database at global-standard.org, searchable by license number or company name, and GOTS is explicit that this database is the only way to independently confirm a claim, since anyone can put an organic label on a product regardless of whether it’s true.
- OEKO-TEX runs a Label Check tool where you enter the certificate number directly.
- WRAP allows verification of certificate status and tier (Silver, Gold, Platinum) through its own compliance site.
- Sedex/SMETA, amfori BSCI, and other audit-based schemes typically require going through the buyer relationship or requesting the report directly, since SMETA and BSCI are audits rather than public certifications, but the underlying platform accounts (Sedex membership, amfori membership) can often be checked for status.
Bookmark whichever scheme applies to your supplier’s claim before you need it urgently.
Step 3: Confirm the Validity Dates
Certificates expire; GOTS, OEKO-TEX, and most Textile Exchange standards require annual renewal. A certificate that was completely genuine when issued tells you nothing about current conditions if the validity window has closed. This is one of the two traps flagged at the start of this article, and it’s the easier one to catch: the database entry will simply show an expired status, or the certificate itself will show a lapsed date range.
Step 4: Confirm the Certified Entity Matches the Facility Quoted
This is where it gets more specific than “check the logo.” The certificate names a certified entity, a specific company, at a specific registered address. That name and address need to match the actual facility making your goods, not a parent company, a sister factory, or a trading company selling on that factory’s behalf.
GOTS is direct about this: the license number “should always be the number of the company that produced the textile product last,” meaning for a printed garment, that’s the printer, not the fabric mill or the original grower. A certificate for the wrong link in the chain doesn’t cover your product, however legitimate it is for whoever it was actually issued to.
Step 5: Confirm the Scope Covers Your Specific Product Category
The final and most commonly skipped check: the certificates list the scope of certification, the specific product categories, processes, or article types the certification actually covers. A facility certified for knit fabric processing isn’t automatically certified for woven goods. A certificate covering apparel may explicitly exclude accessories or trims. Read the scope, not just the logo, and confirm it names your actual product.
Scope Certificate vs. Transaction Certificate, One More Time
This distinction is worth restating in this specific context, because it’s the second trap flagged at the outset, a certificate that’s genuine, current, and still doesn’t protect you.
A scope certificate confirms a facility is certified to process a given standard’s requirements. It’s proof of capability, checked against the public database exactly as described above. What it is explicitly not: GOTS states this outright on its own certificates: “This scope certificate provides no proof that any goods delivered by its holder are GOTS certified.” “Proof of that requires a transaction certificate.
A transaction certificate (TC) is issued for one specific shipment, a defined quantity of certified material, moving from one certified party to the next, listing the actual product and shipment details of that delivery. It’s the only document that ties certification to the literal goods in your order, rather than to the facility’s general capability.
The rule to carry forward: the public database tells you the facility is certified. Only a transaction certificate tells you your specific order was made from certified material. Request both, but understand they answer different questions, and a supplier who only ever offers the first one hasn’t actually proven anything about your shipment.
The Question Almost Nobody Asks: Is Any Part of This Subcontracted?
Here’s the failure mode that undoes an otherwise perfect verification: your supplier holds a genuine, current, correctly scoped certificate, and then quietly subcontracts part of your order to a facility that holds none of that.
Subcontracting disclosure matters because certification databases generally only list entities holding their own certificate directly. GOTS notes this explicitly: facilities “occasionally subcontracted by certified entities to perform specific processing steps” are “not displayed in this database.” “A certified company can legitimately send part of a job to an uncertified subcontractor for a specific process step, and unless you ask, you’d never know from the paperwork alone.
Ask directly: “Is any part of this order, cutting, printing, embellishment, or packing, performed by a subcontractor? If so, is that subcontractor covered under the same certification, and can I see their certificate too?”
A supplier with nothing to hide will answer this without hesitation. One who hesitates, or claims not to know, has just told you something important.
Audit Reports and Corrective Action Plans: The Same Logic Applies

For audit-based schemes (Sedex/SMETA, amfori BSCI, WRAP), the same verification instinct applies to the audit report itself. Ask for the report date, not just the fact that “an audit happened.” Ask whether any findings were raised, and if so, whether a corrective action plan exists and has actually been closed out. A documented plan to fix something is not the same as it being fixed.
Ask, too, whether the audit was announced or unannounced in advance. An unannounced audit, where the facility doesn’t know the exact date ahead of time, generally carries more weight than a scheduled visit a factory has had weeks to prepare for, since conditions observed without advance notice more plausibly reflect normal operating conditions rather than an audit-day performance.

The Fifteen Minutes That Change the Whole Relationship

A certification logo is a claim, not proof. Proof is a certificate number you can independently check, a validity date that hasn’t lapsed, a certified entity that matches your actual factory, a scope that names your actual product, and a straight answer about subcontracting.
None of this requires special access or an enterprise compliance budget. It requires fifteen minutes, a web browser, and a willingness to ask the question most buyers never think to ask. And it changes the shape of the relationship going forward; a supplier who’s already been through this process with you once tends to have their documentation in order the next time, unprompted, because they know it’s coming.
Suppliers who can survive that question, calmly and with the paperwork ready, are exactly the ones worth building a long-term sourcing relationship with. The ones who can’t are telling you something just as clearly, even if they never say a word.
Frequently Asked Questions
How do I check if a factory certificate is real?
Locate the certificate or license number, then search the certifying body’s own public database. GOTS and OEKO-TEX both maintain free, searchable verification tools. Confirm the certificate status is active, the certified entity name matches the actual facility, and the scope covers your specific product category.
Do certification bodies have public databases?
Yes, most major schemes do, including GOTS and OEKO-TEX, though they rarely promote these tools directly to buyers. Audit-based schemes like Sedex/SMETA and amfori BSCI work differently, since they’re verifications rather than public certifications, so obtaining the actual audit report typically requires requesting it from the supplier directly.
What does “scope of certification” mean?
Scope refers to the specific product categories, processes, or article types a certificate actually covers. A facility certified for one product type or process isn’t automatically certified for another, even under the same standard; always confirm the listed scope names for your specific product before relying on the certificate.
Can a certificate be valid but not cover my product?
Yes, and this is one of the most common verification gaps. A scope certificate proves a facility is certified to process a standard’s requirements generally; it does not prove your specific shipment was made from certified material. Only a transaction certificate, issued for your specific order, provides that proof.
What if my factory subcontracts my order?
Ask directly whether any part of your order, cutting, printing, embellishment, or another process, is subcontracted, and request certification for that subcontractor separately. Certification databases generally only list entities holding their own certificate directly, so a subcontractor performing part of your order may not appear in any verification you’ve already done on the primary facility.
