Step-by-step checklist
- Enter the company name or certificate number in the VerifyISO lookup.
- Compare the company name with legal registration and supplier documents.
- Check the ISO standard and scope against the product or service being supplied.
- Confirm current validity dates and watch for expired, suspended, or withdrawn certificates.
- Review the certification body and accreditation evidence where applicable.
- Save the verification evidence with date, source, and reviewer notes.
Why verification matters globally
International procurement teams frequently receive certificates from different countries, languages, certification bodies, and accreditation systems. A structured verification process reduces the risk of accepting outdated, irrelevant, or unsupported certification evidence.
When to escalate
Escalate when certificate data does not match the supplier, the certificate number cannot be found, the certification body cannot confirm the record, or the scope does not cover the goods or services being purchased.
