Verification discipline

A valid number is only the beginning.

Certification lookup confirms what an issuer recorded. It does not prove that the object in front of you is the same object, that the holder is genuine or that nothing has changed since evaluation.

Verify the record, match the object, inspect the holder and preserve the evidence.
01

Use the official source

Enter the certification or report number only on the issuing organization's official website. Search advertisements and screenshots are not authoritative.

  • Type the official domain directly
  • Confirm issuer, number and status
  • Treat unavailable or mismatched records as a stop signal
02

Match every detail

Date, denomination, variety, grade, measurements, weight and comments should agree with the physical object.

  • Compare label text character by character
  • Match photographs when available
  • Investigate any discrepancy before proceeding
03

Inspect security and integrity

Holder construction, seams, holograms, fonts, labels and tamper evidence can reveal substitution or counterfeit packaging.

  • Study current issuer security features
  • Check for opening or resealing
  • Do not rely on a copied certification number
04

Document chain of custody

Invoices, prior listings, high-resolution photographs and ownership records strengthen provenance and help resolve later questions.

  • Save original purchase documentation
  • Photograph identifying marks
  • Record transfers, services and repairs

Decision checklist

Before you assign confidence—or value.

  1. Use the issuing organization's official lookup.
  2. Match all recorded attributes to the object.
  3. Compare issuer images when available.
  4. Inspect holder integrity and security features.
  5. Retain provenance and transaction documentation.

Primary references

Continue with authoritative sources.

Use original records and recognized standards. Third-party summaries should never replace the issuing organization.

NCF perspective

Evidence first. Judgment second. Decision last.
