Define your own certificate-numbering scheme — your prefix, your course symbols, your sequence. Numbers increment automatically, stay sequential per course and company, and never repeat.
Locked on first download so re-issues keep the same number
A scheme that scales
Compose numbers from a prefix, a course symbol and a running sequence so any certificate number tells you at a glance what it is and where it came from — consistently across every batch you ever issue.
Stable for the life of the credential
A certificate number is locked the first time it is issued. Re-downloads and corrections reuse it, so the number on a printed certificate always matches the record and its verification link.
