How to verify a certificate of origin
By the Vanguard Verify desk · Published 2026-10-24 · Updated 2026-11-04
Short answer: verify a certificate of origin (CoO) with whoever issued it. For non-preferential certificates issued by chambers of commerce, use the issuing chamber’s own verification (often a QR code or certificate number lookup) or the ICC World Chambers Federation (WCF) system, which checks the certificate number against the chamber’s accreditation number. For preferential certificates under trade agreements, the customs or designated authority of the exporting country is the issuer to contact.
Two kinds of certificate
| Non-preferential CoO | Preferential CoO | |
|---|---|---|
| Purpose | Proves origin for import rules, LCs, statistics | Claims reduced duty under a trade agreement |
| Usually issued by | Chamber of commerce | Customs or authority named in the agreement (sometimes chambers, or self-declaration) |
| How to verify | Issuing chamber, ICC WCF verification | Exporting country’s competent authority, via your customs |
Step-by-step check
- Read the certificate: issuing body, certificate number, date, exporter, consignee, goods description, HS code, quantity and origin country.
- Match it to the deal. Exporter, consignee, goods and quantity must agree with the invoice, packing list and bill of lading. Check the B/L separately (see how to verify a bill of lading).
- Use the issuer’s verification. Scan the QR code or enter the number on the issuing chamber’s official website — reached by searching for the chamber yourself, not from a link on the document.
- Use the ICC WCF route where it applies. Chambers in the ICC WCF International Certificate of Origin Accreditation Chain issue certificates that can be checked with the unique CO number and the chamber’s accreditation number. The check shows basic details, the issue date and applicant name, and whether that chamber issued that number.
- Contact the chamber by email or phone found on its official site and ask it to confirm the certificate.
- Check the exporter exists and is active in its company registry.
Red flags
- The QR code or link goes to a site that is not the chamber’s official domain.
- The exporter on the CoO is a different company from the seller on your contract, with no explanation.
- Origin is a producing country the exporter has no visible link to.
- Goods description or quantity differs from the invoice or inspection report (see how to verify an SGS report).
- The certificate is dated before the contract or long after shipment.
- The seller refuses to let you contact the issuing chamber.
A genuine CoO confirms origin declared for a shipment. It does not prove the goods were loaded or that the seller can perform — check the company too.

FAQ
Who issues a certificate of origin?
Non-preferential certificates are usually issued by chambers of commerce. Preferential certificates are issued by the customs or other authority named in the trade agreement, and some agreements allow exporter self-declarations.
What is the ICC WCF certificate of origin verification?
A system for certificates issued by chambers in the ICC World Chambers Federation accreditation chain. Entering the unique CO number and the chamber's accreditation number shows basic certificate details and whether that chamber issued it.
Does a valid CoO prove the cargo exists?
No. It confirms the declared origin for a shipment. Verify the bill of lading, inspection report and the seller company separately.
How do I check if a certificate of origin is genuine?
Contact the issuing chamber or customs authority directly, using contact details you find yourself, and quote the certificate number. If the chamber is in the ICC WCF accreditation chain, enter the certificate number and the chamber's accreditation number in the WCF verification system. Then match the exporter, consignee, goods and quantity to your invoice and bill of lading.
Can I do a certificate of origin verification online?
Often, yes. Many chambers and e-certificate platforms print a QR code or verification link on the certificate, and WCF-accredited chambers can be checked through the ICC WCF system. A QR code or website link supplied only by the seller is not proof on its own: reach the issuer through its official website.
