Buyers, retailers and integrators can check a sustainability certificate published on Label Registry without signing in. This guide describes the public verification flow available today. It is not legal advice.

What you can check publicly
On this product, verified live features include:
- A searchable public registry of published certificates.
- Public scheme pages for published schemes with a frozen version.
- A certificate page per published certificate (holder, scope, validity, status history).
- A verification URL opened from the QR code on a printed certificate (same content as the certificate page).
- The EmpCo check (Diagnostic EmpCo) for scheme owners assessing Article 2, point (r).
Glint publishes Label Registry. Glint is not a certification body and does not decide whether a certificate is valid in law.
Step 1: open the public registry
Go to the public registry. Search by certificate number, holder name or scheme name. Only certificates tied to a published scheme appear.
The demo seed on this site includes certificate ECOV-2026-000001. You can search for `ECOV` or `000001` to find it.
Step 2: open the certificate page
Select a result to open its certificate page, for example ECOV-2026-000001. You will see:
- Certificate number and linked scheme name.
- Holder and independent verifier name when recorded.
- Scope, validity dates and current status.
- A short status history when events were published.
Step 3: verify with a QR code
Scheme owners can print a certificate card from their workspace. The print view embeds a QR code that points to a verification URL with a public token, for example `/en/verify/seedtokenECOV2026000001` for the demo certificate.
Scanning the code or opening that URL shows the same certificate data as the numbered certificate page. Token URLs are meant for QR access; search engines are discouraged from indexing them, while the numbered certificate page remains indexable.
Integrators can also fetch the QR as SVG from `/api/public/v1/certificates/{token}/qr.svg` when they know the public token.
Step 4: read the published scheme
From the certificate page, open the linked scheme page to read the frozen version that applied when the certificate was issued. Compare scope and requirements with what the holder claims in market materials.
