Checking a ZOLB Circuit Lab certificate

To check a certificate yourself:scan the QR code on the PDF, or open the verification link the holder shared with you. The page shows whether the certificate is valid and what it was awarded for. The holder's name is partly hidden on purpose.
If the page says “Certificate not found”: the holder may have switched verification off or made a new link. Ask them for the current link.
For anything else(a certificate you can't verify, a correction, or a concern about a certificate), contact us here and include the certificate ID if you have it. We never confirm personal details beyond what the verification page shows.
