How to verify a certificate's authenticity

A certificate is only as useful as it is trusted. If a credential can't be checked, it carries no weight; if yours can be checked easily, it carries more. Here's both sides: how to verify a certificate you've received, and how to make the ones you issue verifiable.

If you're checking a certificate

Most verification is common sense applied carefully:

• Confirm the issuer: is the organization named real, and do they actually run the event or program claimed?
• Look for a reference or accreditation ID: a unique code you can quote back to the issuer.
• Contact the issuer directly using details you find independently, not ones printed on the certificate.
• Inspect for tampering: mismatched fonts, misaligned text, or a name that looks pasted in are red flags.

If you're issuing certificates

You make verification easy by being consistent and keeping records:

• Use a unique reference ID per certificate so any single one can be looked up.
• Keep your template consistent so genuine certificates share a recognizable look.
• Maintain an issuance log of who received what, and when.
• Publish a simple way to confirm a certificate, even an email address people can write to.

Why an issuance log matters

The single most useful thing an issuer can keep is a record of every certificate issued. When someone asks 'is this real?', you check the log. Certificatory logs every certificate generated (recipient name, timestamp, and download count) and lets you export the full record as CSV, so you always have the receipts.
