CV fraud: how employers spot fake CVs and diplomas

How to spot CV fraud: fake CVs, diplomas and references

The candidate with the perfect degree, a strong track record and glowing references is exactly who you want to hire. It is also exactly what a fraudster will show you. CV fraud ranges from a stretched job title to a diploma bought online, and most of it is only found when someone checks. For example, in a 2025 YouGov survey for the UK verification service Hedd, 45% of large employers had caught an applicant giving false information about their qualifications (Prospects, July 2025).

Hence, this guide explains what counts as CV fraud, which warning signs to look for, how to verify diplomas and references, and what to do when the facts don't match the CV.

What counts as CV fraud?

CV fraud is any false or misleading claim a candidate makes to get hired. It sits on a scale. At one end is embellishment: a junior role described as a management position, or a six-month contract stretched to a year. At the other end is outright fabrication: a degree that was never earned, an employer that never existed, a referee who is really a friend.

The most common types are:

• Inflated job titles: "team lead" on the CV, "assistant" in the employer's records
• Adjusted dates: covering a gap, a dismissal or a short job that didn't work out
• Invented employers: a company that has closed, is abroad, or never existed
• False or upgraded qualifications: claiming a degree that wasn't finished, or a higher grade
• Fake diplomas: forged certificates, or degrees from diploma mills
• Rigged references: a friend or relative posing as a former manager

The line between "selling yourself well" and fraud is a factual one. If a claim can be checked and the check shows it is untrue, it is a discrepancy you need to deal with.

How common is CV fraud?

CV fraud is common enough that every employer who screens will run into it. The exact rate depends on who checks what, because fraud only shows up where someone verifies. For instance:

• More than three in four employers found candidate discrepancies in the past 12 months, and in Europe, the Middle East and Africa 47% found problems with education credentials (HireRight, 2025 Global Benchmark Report).
• Employment history is where discrepancies turn up most often: 64% of EMEA respondents found them in employment verifications (HireRight, 2025 Global Benchmark Report).
• A quarter of almost 55,000 CVs screened in the UK contained inconsistencies (Credence and Prospects, CVs Uncovered 2019).

At the same time, many employers still take CVs on trust. Only 52% of large UK businesses check all academic credentials, and 26% of small businesses don't check qualifications at all (Hedd and YouGov, 2025). Smaller firms report less fraud, but partly because they look for it less.

AI makes the problem bigger. Generative tools write a polished CV in seconds and make it easy to invent plausible experience. In the same Hedd survey, 67% of large companies had seen job application fraud rise and linked it to AI tools.

Warning signs of a fake CV

No single red flag proves fraud, and many have an innocent explanation. Treat them as prompts to ask questions and to verify, not as grounds to reject someone.

On the CV

• Dates given in years only ("2019-2021"), which can hide gaps or short jobs
• Job titles that don't fit the company's size, or a steep jump in seniority
• Employers that are hard to find online, have closed, or are based abroad with no contact details
• Degrees from institutions you have never heard of, especially ones that award degrees for "life experience"
• A CV that differs from the candidate's LinkedIn profile or an earlier application
• Vague achievements with no names, numbers or projects behind them

In the interview

• Answers stay general when you ask for details about a role, a manager or a project
• The candidate cannot explain what they actually studied or who taught them
• The story changes between interview rounds
• Reluctance to give consent for a background check, or to name a direct manager as a referee

A good tactic is to ask the same factual question twice, in different words and at different moments. Genuine experience produces consistent, detailed answers.

How to spot a fake diploma

You cannot reliably spot a fake diploma by looking at it. Forged certificates copy real university logos, seals and signatures, and a scan or photo hides most signs of tampering. The only reliable test is to confirm the qualification with the institution that issued it.

Fake diplomas come in two forms:

• Forged or altered certificates from real institutions, for example a changed name, subject, grade or graduation year.
• Degrees from diploma mills: organizations that sell degrees with little or no study.

To verify a diploma properly:

1. Ask for the full details: institution, programme, degree level, graduation date and student number if available.
2. Check that the institution is accredited in its own country, not just that it has a website.
3. Confirm the qualification at the source: the institution itself or a national register, such as DUO in the Netherlands or Hedd in the UK.
4. Don't rely on a copy, even a certified one. A notary confirms that they saw a document, not that the document is genuine.
5. For foreign diplomas, use a screening provider with access to institutions abroad, because replies can take weeks if you write to a registrar yourself.

With a qualification check, Pescheck verifies diplomas and certificates directly with the issuing institution, in the Netherlands and abroad, so you know the candidate holds the qualification they claim.

How to check references properly

A reference only protects you if the person you speak to is who they say they are. The classic trick is simple: the candidate gives a friend's number, and the friend plays the former manager. Some candidates go further and list a mobile number and a private email address for a "company" that only exists on paper.

To make a reference check hold up:

1. Find the contact yourself. Call the company's main number or use its official email domain, then ask to be put through. Don't rely only on the number on the CV.
2. Confirm the facts first. Ask for job title, start and end date and the referee's own role. These can be checked and should match the CV.
3. Then ask about performance. Ask for concrete examples: what the candidate was responsible for, how they worked with others, and whether the referee would hire them again.
4. Listen for vagueness. A real manager remembers specific projects and colleagues. A stand-in usually doesn't.
5. Check more than one referee, ideally a direct manager from each of the last two jobs.

A reference check by Pescheck follows this method in a consistent, documented way, so every candidate is checked to the same standard and you have a record of what was confirmed.

A screening process that catches CV fraud

The best defence is a standard process that checks every candidate for a role in the same way, before they start. That is fairer to candidates and much harder to game.

1. Decide per role what to check. A finance role needs different checks from a warehouse role. Check what is relevant to the job, and no more.
2. Say it in the vacancy. Mention that qualifications, work history and references will be verified. This alone puts off some dishonest applicants.
3. Inform the candidate and ask for consent where required. Explain which checks you will run, why, and how long you will keep the data. Under the GDPR, screening needs a clear purpose and must be proportionate to the role.
4. Verify at the source. Diplomas with the institution or a national register, employment with the employer, references through official channels.
5. Compare the results with the CV. Note every discrepancy, however small, and keep the evidence.
6. Give the candidate a chance to respond before you decide anything.
7. Delete what you no longer need. Keep screening data only as long as necessary.

Screening runs faster and more consistently when you don't do it by hand. Pescheck combines identity, qualification, employment and reference checks in one platform, with the candidate giving consent online.

What to do when you find a discrepancy

A discrepancy is not automatically fraud. Dates can be off by a month, companies merge and change names, and some degrees are awarded under a different title than the one people use. Start with a conversation, not a conclusion.

• Ask the candidate to explain. Share what you found and give them a fair chance to clarify or provide evidence.
• Weigh it against the role. A wrong end date is not the same as a fake medical or engineering degree. Ask whether the false claim affects the candidate's ability or right to do the job.
• Document your decision. Record what you found, what the candidate said, and why you decided as you did.
• If the fraud is serious, you can withdraw the offer. If the person already works for you, take legal advice before acting: depending on the country and the contract, deliberate CV fraud can justify dismissal, and a forged document may be a criminal offence.

Whatever you decide, apply the same standard to every candidate.

Frequently asked questions

• What is CV fraud?

CV fraud is giving false or misleading information on a CV or job application to get hired. It includes inflated job titles, changed dates, invented employers, fake diplomas and fake references.

• Is lying on a CV illegal?

It depends on the country and the lie. Exaggerating usually isn't a crime, but presenting a forged diploma or reference can be fraud or forgery. In many countries, an employer can also dismiss an employee who was hired on the basis of serious CV fraud.

• How can I check if a CV is real?

Verify the claims at the source. Confirm qualifications with the issuing institution, employment with former employers, and references through official company contact details. A background screening provider can do this for you.

• How do I know if a diploma is fake?

You usually can't tell by looking. Check that the institution is accredited, then confirm the qualification with the institution or a national register. A qualification check does this for you.

• Can I screen a candidate without their consent?

You must tell candidates in advance which checks you will run and why, and in many cases you need their consent. Only check what is relevant to the role.

• How long does a CV check take?

It depends on the checks and the countries involved. Domestic checks are often completed in days; verifying a foreign diploma can take longer because it depends on the institution's response.
