The certificate is signed by someone nobody knows

A certificate is worth whatever its issuer is worth. Checking takes three minutes and almost nobody spends them.

Updated on 13/08/2026

A certificate arrives with a stamp, a reference number and an impeccable look. It gets filed. Months later someone asks who issued it and it turns out to be a body nobody has heard of, appearing in no register, whose website runs to three pages. The document is not fake — it simply evidences nothing.

The four grades, and only the first is fraud

What it isWhat it is worth
A forged documentNothing, and it is a serious problem besides
Genuine, from an unrecognised bodyLittle: it is one company's opinion
Genuine, but of another scopeGood for its own scope, not for yours
Genuine, recognised and currentWhat you were after

Important

**The row that shows up most in real life is the second, and it is not fraud: it is marketing.** One company pays another to review something and receives a document saying so. All true, all genuine, and worthless to whoever requires accreditation of you — because what is required is not that somebody certifies it, but that it is certified by whoever is recognised to do so. Telling those apart is exactly the work nobody does at filing time.

Three checks, three minutes

  1. 1

    Search for the issuer by name and number

    Recognised bodies appear in public, searchable registers.

  2. 2

    Read the certificate's scope, not just its title

    It is usually in the small print, and that is where cover shows.

  3. 3

    And check the date and the status

    A suspended or withdrawn certificate looks exactly the same.

Watch out

One detail separates those who check from those who file: **the certificate you need is the one for the specific product or process, not for the company**. A manufacturer holding a management certification says nothing about whether THAT model meets what you need. It is the most commercially exploited confusion and the easiest to undo: look for what you are buying inside the certificate.

Worth knowing

Which accreditation is required in each case, which bodies are recognised to issue it and how currency is verified depends on the product, the sector and the country. **Your adviser or the relevant body settles that**; here we explain how to spot the case where a genuine document evidences less than it appears to.

Is a stamped certificate valid?

The stamp is not the evidence. The issuer and the scope are.

Can I ask the supplier to justify it?

Yes, and an evasive answer is itself information.

What if the issuer is in no register?

Treat it as a supplier declaration, which is a different thing.

A real case

The situation

A supplier hands over a certificate from a body that appears in no register.

What you do

  1. Looks the issuer up before filing and treats it as a supplier declaration

What you get

The file reflects what that paper actually evidences, which is less than it seemed.

The situation

The manufacturer's management certification is filed in the belief it covers the product.

What you do

  1. Checks whether the model being bought appears in the certificate's scope

What you get

It emerges in time that the product document was missing, not the company one.

The situation

A valid-looking certificate has been withdrawn for months and the paper looks just as impeccable.

What you do

  1. Checks the status and currency, not only the printed date

What you get

The file stops resting on a document that is no longer in force.

The situation

A certificate arrives and is filed without looking at who issued it.

What you do

  1. Checks the issuer before accepting it

What you get

A certificate is worth what its signatory is worth.

The situation

The issuer cannot be found anywhere.

What you do

  1. Asks the supplier and records the answer

What you get

The doubt is settled before a client settles it.

The situation

A client asks about the issuer of one of your certificates.

What you do

  1. Checks what was recorded on receipt

What you get

You answer without phoning the supplier.
