How to Make Your Institute's Certificates Verifiable, and Why Employers Check

By Pooja Goenka · Published 2026-10-02 · Updated 2026-10-14

To make your institute's certificates verifiable, give each one a unique ID and print a link or QR code on it that opens a public page showing the name, course, date and result. Then anyone, years later, can check it in about a minute without having to reach you.

I should say first that we build an exam platform that issues verifiable certificates. Most of this applies whatever software you use, including none.

A student finishes your course, passes the exam and gets a certificate. A year later it is a PDF attached to a job application, a line on a LinkedIn profile, or a photo in a hiring manager's inbox. You are not there to vouch for it, so it comes down to whether the person reading it can tell it is real.

For most institutes they can't. A PDF with a logo and a signature can be edited in a few minutes, and the reader knows it. So the certificate, which should be the strongest proof of your teaching, ends up counting for very little.

Why do employers check certificates?

A recruiter will usually read a certificate they cannot check as something the candidate claims about themselves. If they cannot verify it in a minute, the options are to ignore it or to email you and wait, and few recruiters wait.

You rarely see what this costs. A student with your certificate gets less credit for it than they earned, and your institute's name gets less credit with them.

What are the ways to make a certificate verifiable?

1. A phone number or email on the certificate. Better than nothing, and the most common. It relies on someone at your institute answering, finding the record and replying, months or years later. In practice it is rarely used.

2. A certificate ID with a lookup page. Each certificate gets a unique ID, and your website has a page where anyone can type it and see the name, course, date and result. This is the minimum that works without you. The weakness is that the lookup page proves the ID exists, but a forger can copy a real ID onto a different name unless the page shows the details clearly.

3. A link or QR code to the record. This is the lookup page without the typing: the reader scans or clicks and lands on your record. It is faster, and a good page shows exactly what was awarded, so a mismatch with the PDF is obvious.

4. A cryptographic hash of the certificate. The certificate's details (name, course, score, date and ID) are run through a hash function such as SHA-256, defined in NIST's Secure Hash Standard, which produces a fixed string of characters. Change one letter of the name and the hash changes completely. You store the hash. Anyone checking a certificate recomputes it, or uses your verification page to do so, and compares. If they match, the details have not been altered since you issued them.

What does a certificate hash prove, and what does it not?

A hash proves the details on the certificate are exactly the ones you issued. It does not prove the person holding it is the person named on it, and it does not prove the exam was taken honestly. That is what your proctoring and identity checks are for, and the certificate is only as trustworthy as the exam behind it.

It also does not need a blockchain. Some vendors sell "blockchain certificates" as if the chain is what makes them verifiable. The hash does that work. A blockchain only adds a public timestamp of when the hash was recorded, which matters for a few use cases and not for most coaching institutes.

If you need certificates that other software can read and check automatically, there are open standards for that: the W3C's Verifiable Credentials Data Model 2.0, a W3C Recommendation since May 2025, and 1EdTech's Open Badges 3.0. Most institutes do not need either to start, and a clear public verification page covers what a recruiter actually does. In India, degree and board certificates have a government route too: DigiLocker and the National Academic Depository let issuers publish records that verifiers can check online.

What should you ask of any certificate system?

Ask these of your current setup, or of any vendor:

1. Can someone verify a certificate without contacting you?
2. Does the verification page show the name, course, date and result, so a copied ID on a different name is caught?
3. Is there a link or QR code on the certificate itself?
4. What happens if you revoke a certificate, for example after a cheating finding? Does the verification page say so?
5. Does verification keep working if you change vendors? Can you export the records and hashes?
6. Is the verification page under your institute's name and domain, or the vendor's? Students share your brand, so the page should carry it. We wrote more about what white-label actually means for an exam platform.
7. Does the certificate say what was assessed, such as "60 questions, proctored, 70% pass mark", and not just "completed"?

Institutes often skip the last one. "Certificate of completion" tells an employer the student attended. "Passed a proctored assessment" tells them the student can do something.

Is there a free certificate generator with QR verification?

Yes, several, though "free" and "QR" do not always come together. Here is what each tool's own page says, checked on 14 October 2026:

A generator makes a certificate checkable. It does not make the assessment behind it any stronger, so if the certificate is meant to show a skill, pair it with a real exam and say so on the certificate. Run any of these through the checklist above, especially questions 5 and 6 on exporting records and whose domain the verification page sits on.

Where LogicWiz Exams fits

LogicWiz Exams issues certificates with a certificate number, a short code and a QR code. The public check shows whether each one is valid, expired or revoked, and who issued it, and an employer can confirm the name a candidate gave them. The exam behind it can be multiple choice, written answers with AI-suggested marks a teacher reviews, coding, or handwritten answers photographed with a phone, with optional proctoring. If you use something else, run it through the checklist above.

Common questions

How can an employer verify a certificate?

The fastest way is a verification page run by the institute: the employer enters the certificate ID or scans a QR code and sees the name, course, date and result. If the certificate has a hash, the page can confirm the details have not been edited since issue.

What is a SHA-256 certificate hash?

It is a fixed-length fingerprint computed from the certificate's details. Changing any detail, even one letter, produces a completely different fingerprint, so a matching hash shows the certificate is unaltered.

Do verifiable certificates need a blockchain?

No. The hash makes the certificate tamper-evident. A blockchain only adds a public record of when the hash was stored, which most coaching institutes do not need.

Can a verifiable certificate still be faked?

The details cannot be changed without the check failing, but someone could try to pass off another person's real certificate. That is why the verification page should show the name clearly, and why the exam itself needs identity checks.

What should a certificate say about the assessment?

What was tested and how: the subject, the number of questions or tasks, whether it was proctored, and the pass mark. With those details an employer can see the student was tested, which a plain completion line does not show.

Is there a free certificate generator with QR verification?

Yes. Eklavvya's free bulk generator adds a unique ID and QR code to each certificate with a hosted verify page, and CertPie's free plan covers 30 certificates a month with QR verification. On Certify'em the QR code is a paid feature, and CertFusion offers a short trial. Check whether the verification page can carry your institute's name before you choose.

How are degree certificates verified in India?

Many universities and boards publish records to DigiLocker and the National Academic Depository, where an employer or verifier can check them online. For course and coaching certificates, which are usually not on DigiLocker, use the issuer's own verification page.
