A convincing aviation document still needs a check with the organization that supposedly issued it. Find that organization through an independent official channel, then confirm which record it issued and what the record authorizes.

This is useful when receiving a regulatory clearance, training certificate or supplier document. A familiar logo helps you recognize the claimed source. It does not establish that the source created this particular file.

Start with the question the document must answer

Before checking signatures or reference numbers, identify why you need the document. Does it show that a person completed a course, that an organization holds an approval, or that an authority permitted a particular activity?

Those are different claims. A genuine certificate of course completion does not automatically authorize the holder to perform a regulated task. The document's purpose, conditions and dates need to match the decision in front of you.

Ask the person who supplied it for a readable, complete copy, including any pages that define its scope. A missing page is a question to resolve, not evidence that the supplier committed fraud.

Reach the organization independently

Use contact details or a verification service obtained from the organization's official website or an established official directory. Do not let the questioned document be your only source for the person who will confirm it.

Send a focused request through the channel's prescribed process:

  • Identify the document by its reference, recipient and issue date.
  • Ask whether the organization issued that record and whether the copy matches it.
  • Ask whether the signatory had the relevant authority and whether any limitation or later change affects the intended use.

These are suggested questions, not a universal regulatory form. The organization may use its own process and require the holder's consent. Provide the information it needs through the appropriate channel rather than circulating an entire personal file.

Keep the response with the document. Record who answered, how you reached them, when they checked and anything their answer did not cover. A confirmation that a reference exists may leave its current scope unresolved.

A short example

In this fictional example, Lee receives a supplier's approval letter for a proposed activity. The letter has an official logo, but its attachment describing the approved scope is missing.

Lee asks the supplier for the attachment and independently contacts the named authority. The authority confirms that it issued a letter with that reference, but the permitted activity in its record differs from the supplier's proposed work.

The useful finding is specific: this letter does not establish the permission Lee needs. Lee records the mismatch and asks the person responsible for approval to resolve it. There is no need to infer why the supplier sent the wrong document.

What a digital proof adds

A digital signature can help detect changes and connect a record to a signing key. You still need a trustworthy link between that key and the organization, plus a reason to accept the organization's claim for this purpose.

The W3C Verifiable Credentials Data Model 2.0, checked September 12, 2026, distinguishes technical verification from deciding whether the claims should be accepted. A successful signature check does not make every statement true or give the issuer unlimited authority.

If a document has a status service, check what it reports and when. An unavailable service leaves a question open; it is not an answer about the holder or the document.
