Certificate ID or tracking code: which to enter on the verification page

The public verification page at /verify.html has two separate boxes, and it helps to know which to use.

• Certificate ID — enter this in the Certificate ID field and press Verify. The certificate ID is the unique reference printed on your PDF delivery certificate.
• Tracking code — enter this in the Tracking Code field and press Track. The tracking code is also shown on the certificate and in your confirmation email.

Either will let you — or your recipient — confirm an email's delivery status. No account is needed to use the verification page, so anyone you share a reference with can check it.

A practical tip: when you send someone proof, give them the verification link together with the reference they need to type in. If you have the PDF certificate to hand, the certificate ID is the most direct thing to quote; if you are working from the confirmation email, the tracking code is just as good. Both point at the same delivery record.
