Official lookup
Use the certificate ID and holder details requested by the Linux Foundation verification form. Confirm the credential title and validity. Provider form checks are performed on their website.
If your award has a public Credly badge, you can import its URL. CertSprout automatically checks supported Credly and Microsoft Learn records. Provider-site lookups and manually attached links do not automatically mark a credential verified. A public record confirms the award; it does not prove the signed-in user owns it.
