Quick answer
Yes, with serious consequences: reviewers compare originals, QR codes and system records via verification channels. Changing validity, number, scope or address is document fraud; the proof becomes invalid, the whole filing loses credibility, and it may be returned or revoked. A Kunming mushroom processor had its whole material chain rejected after the expiry date was edited out. Request the newest original, or change supplier or material; doubtful files must be reissued.
Detailed explanation
Common edits and detection points
- Changed validity, certificate number or issue date, with mismatched fonts or background tone.
- Scope enlarged, turning a company-level certificate into grade-level coverage.
- Another factory's address spliced in, while the QR code resolves to different text.
Consequences after fraud is found
- The proof is voided and all related materials count as source-unverified.
- The current filing is returned or halted, and other files receive stricter checks.
- If discovered after issuance, suspension or revocation procedures may follow.
What to do with an expired or mismatched certificate
Ask the supplier for the newest original immediately and keep the communication record; if it cannot be supplied quickly, switch to an alternative material with valid proof. The Kunming company files the verification screenshot with date in the supplier record and presents it in the audit, which carries more weight than verbal explanations.
