Why certificate verification matters
A language certificate printed at home costs nothing to fake. Candidates know this, and a small number take advantage of it. Research from the Society for Human Resource Management found that 85% of employers caught applicants lying on their CV at least once, and language skills are among the easiest claims to embellish.
Verification removes the doubt in under 60 seconds. That time investment is negligible compared to the cost of hiring someone whose actual proficiency falls short of the role's requirements, particularly in client-facing or regulated positions.
How to verify a CEFR certificate
Most modern language certificates reference the CEFR levels framework, which runs from A1 (beginner) to C2 (mastery). Knowing the level alone is not enough. You need to confirm that the specific certificate in your hand was issued to the person sitting in front of you.
For Examinizer certificates, the process takes three steps. Go to examinizer.net/verify/, enter the certificate ID printed on the document, or scan the QR code with any smartphone camera. The page immediately returns the candidate's full name, the language tested, the CEFR level awarded, and the exact test date.
If a candidate hands you a certificate showing B2 English issued on 14 March 2025, you enter the ID or scan the code, and the record either matches those details exactly or it does not. There is no grey area. A mismatch is a red flag worth exploring before the hire proceeds.
Red flags: signs of a fake certificate
Fraudulent certificates tend to share predictable weaknesses. Knowing what to look for lets you catch problems before you run a formal check.
- No verification code or QR code. A legitimate certificate from any reputable provider includes a unique credential identifier. A document that shows only a logo and a level, with nothing to verify against, cannot be confirmed as genuine.
- A verification link that leads nowhere. Test the URL printed on the certificate. If it returns a 404 error, redirects to a generic homepage, or produces an "ID not found" message for a certificate that supposedly exists, treat the document as suspect.
- Inconsistent formatting or spelling. Compare the document against samples published on the issuer's official website. Font mismatches, incorrect logos, spelling errors in the provider's own name, and off-center layouts are common signs of a home-printed forgery.
- A level that does not match interview performance. A candidate who holds a C1 certificate but struggles to follow simple questions in that language during the interview warrants a closer look. You can ask them to take a free language test on the spot to cross-check the claim.

How Examinizer's QR verification works
Each Examinizer certificate carries a QR code that encodes a unique credential ID. That ID is tied directly to the original test record stored in Examinizer's database, not to anything printed on the paper itself.
When you scan the code, your device sends that credential ID to Examinizer's servers and retrieves the stored record in real time. The system returns only what the database holds. Because the record lives server-side and the recruiter queries it directly, there is nothing on the certificate that a candidate can alter to produce a different result.
This architecture means a doctored certificate, where someone has changed the name or the level before printing, will either return the original unmodified data or fail to return any record at all. Either outcome tells you what you need to know.
What information the verification page shows
The verification page displays five data points for every valid certificate.
- Candidate name. The full name of the person who sat the test, as registered at the time of the assessment.
- Language tested. The specific language the certificate covers, for example English, French, or German.
- CEFR level. The official level awarded, from A1 to C2.
- Score. The numeric or percentage score underlying the level, giving you a precise measure rather than a broad band.
- Issue date. The date the certificate was generated, which lets you judge how current the qualification is.
Cross-reference the name against the candidate's ID and the level against the role's requirements. If both match, you have confirmation. If either differs from what the candidate presented, you have a discrepancy to address before moving forward.
Verification methods compared
| Verification method | What it confirms | Time needed |
|---|---|---|
| QR code scan (Examinizer) | Name, language, CEFR level, score, issue date, against live database record | Under 10 seconds |
| Manual ID entry at examinizer.net/verify/ | Same as QR scan, useful if camera is unavailable | Under 30 seconds |
| Contacting the issuing body directly | Confirms authenticity, but depends on the provider's response process | 1 to 5 business days |
| Live interview assessment | Observed proficiency in context, not documentary authenticity | 15 to 30 minutes |
| Asking the candidate to take a new test | Current demonstrated level, independent of the original certificate | 20 to 45 minutes |
For high-stakes roles, combine at least two methods. A QR scan confirms the document, and a live test or interview confirms the person. Using both together removes any remaining ambiguity.
Building verification into your hiring process
The most reliable approach is to treat language certificate verification as a standard pre-offer step, the same way you would check references or confirm qualifications. Designate one person in the HR team to run the check for every role that lists a language requirement.
If your organisation screens large volumes of candidates, corporate plans for teams let you centralise testing and verification so HR has access to results directly, without relying on documents submitted by candidates at all. That removes the forgery risk at source.
For individual candidates who have not yet been tested, you can ask them to take a free language test before the interview. The result is an independently verified record you control from the start.
It is also worth knowing that employers who verify language certificates before making an offer report fewer post-hire performance gaps related to communication. The check is quick, it is free for Examinizer certificates, and it sets a clear standard that candidates are aware of from the outset.
FAQ
Is certificate verification free?
Yes. Verifying an Examinizer certificate at examinizer.net/verify/ costs nothing. You enter the certificate ID or scan the QR code, and the result appears immediately at no charge. There are no subscription fees or pay-per-check costs for the employer running the verification. The service is designed to be accessible to any recruiter or HR professional.
Do I need an account to verify a certificate?
No account is required. The verification page is publicly accessible. Any employer, recruiter, or HR staff member can go to examinizer.net/verify/, enter the credential ID or scan the QR code from the certificate, and see the result without logging in or registering. The process is intentionally straightforward so that verification becomes a routine step rather than a barrier.
What should I do if a certificate fails to verify?
A failed verification means the ID entered does not match any record in the database. First, confirm the ID was entered correctly, including any hyphens or capitalisation. If the check still fails, treat the certificate as unverified and ask the candidate for an explanation. You can also ask them to sit a new test to establish their actual level independently before you make a decision.
Does verification work for certificates from other providers?
The examinizer.net/verify/ tool confirms only Examinizer certificates. For certificates from other providers, such as Cambridge, IELTS, DELF, or Goethe-Institut, you need to use that provider's own verification portal. Each major awarding body publishes a verification URL on its official website. If a certificate from another provider carries no verification mechanism at all, that absence is itself a red flag.
How recent does a certificate need to be to be considered valid?
There is no single universal rule, but most employers treat certificates older than two years with some caution, particularly for roles where communication is central. Language proficiency can change with practice or disuse. The verification page shows the issue date, so you can factor recency into your decision. For roles with strict language requirements, asking for a fresh test is a reasonable standard to apply consistently.
